+ property
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This property specifies slot power limit in mW unit. It is a form-factor
+and board specific value and must be initialized by hardware.
+
+Some PCIe controllers delegate this work to software to allow hardware
+flexibility and therefore this property basically specifies what should
+host bridge program into PCIe Slot Capabilities registers.
+
+The property needs to be specified in mW unit instead of the special format
+defined by Slot Capabilities (which encodes scaling factor or different
+unit). Host drivers should convert the value from mW to needed format.

+ to real HW value
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+mvebu and aardvark HW have PCIe capabilities on different offset in PCI
+config space. Extend pci-bridge-emul.c code to allow setting custom driver
+custom value where PCIe capabilities starts.
+
+With this change PCIe capabilities of both drivers are reported at the same
+location as where they are reported by U-Boot - in their real HW offset.

+ interrupt handler
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Same as in commit a3b69dd0ad62 ("Revert "PCI: aardvark: Rewrite IRQ code to
+chained IRQ handler"") for pci-aardvark driver, use devm_request_irq()
+instead of chained IRQ handler in pci-mvebu.c driver.
+
+This change fixes affinity support and allows to pin interrupts from
+different PCIe controllers to different CPU cores.
+
+Fixes: ec075262648f ("PCI: mvebu: Implement support for legacy INTx interrupts")

+
+Documentation for irq_domain_remove() says that all mapping within the
+domain must be disposed prior to domain remove.
+
+Currently INTx irqs are not disposed in pci-mvebu.c device unbind callback
+which cause that kernel crashes after unloading driver and trying to read
+/sys/kernel/debug/irq/irqs/<num> or /proc/interrupts.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Replace assignment of PCI domain from atomic_inc_return() to ida_alloc().
+
+Use two IDAs, one for static domain allocations (those which are defined in
+device tree) and second for dynamic allocations (all other).
+
+During removal of root bus / host bridge release also allocated domain id.
+So released id can be reused again, for example in situation when
+dynamically loading and unloading native PCI host bridge drivers.
+
+This change also allows to mix static device tree assignment and dynamic by
+kernel as all static allocations are reserved in dynamic pool.

-Subject: [PATCH 08/10] ARM: dts: mvebu: armada-385-turris-omnia: separate dts
- for SFP and PHY
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The Turris Omnia board contains dual-personality ethernet NIC eth2 with
-two operation modes: 1) SFP cage and 2) metalic 1000BASE-X PHY.
-The differential pair carrying SGMII/1000BASE-X of eth2 is wired through
-a multiplexor driven by the module-detect signal from the SFP cage.
-The pin status can be read through I2C GPIO expander chip in userspace
-when the sfp driver module is unloaded and / or in U-Boot prior to the
-start of the kernel and the proper DTS file can be selected for the
-(floolowing) boot.
-
-Split DTS for Turris Omnia (that does not have any support for SFP cage)
-into three files:
- armada-385-turris-omnia.dtsi - common base
- armada-385-turris-omnia-sfp.dts - DT with the SFP configuration and
-PHY disabled
- armada-385-turris-omnia-phy.dts - DT with the PHY configuration and
-SFP disabled
-
-Current DSA driver does not allow multiple CPU ports and Turris Omnia
-has two RGMII iterfaces wired between CPU and DSA switch.
-Disable the second CPU port until there is a suitable driver to use it.

+ emulated bridge
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This adds support for PME and ERR interrupts reported by emulated bridge
+(for PME and AER kernel drivers) via new Root Port irq chip as these
+interrupts from PCIe Root Ports are handled by mvebu hardware completely
+separately from INTx and MSI interrupts send by real PCIe devices.
+
+With this change, kernel PME and AER drivers start working as they can
+acquire required interrupt lines (provided by mvebu rp virtual irq chip).
+
+Note that for this support, device tree files has to be properly adjusted
+to provide "interrupts" or "interrupts-extended" property with error
+interrupt source and "interrupt-names" property with "error" string.
+
+If device tree files do not provide these properties then driver would work
+as before and would not provide interrupts on emulated bridge, like before.

+ hot plug interrupt
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+If link up/down state is changed in mvebu_pcie_link_up() then trigger
+hot plug interrupt with DLLSC state change.
+
+Also triggers hot plug interrupt when mvebu triggers Link Failure interrupt
+which indicates that link was changed from active state or when mvebu
+triggers TxReq No Link interrupt which indicates that link is down while
+trying to transmit PCIe transaction.
+
+And this hot plug interrupt also when explicit Link Disable or PCIe Host
+Reset is issued as mvebu does not trigger Link Failure when dropping to
+Detect via Hot Reset or Link Disable.

+Subject: [PATCH 19/96] PCI: aardvark: Add support for AER registers on
+ emulated bridge
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Aardvark controller supports Advanced Error Reporting configuration
+registers.
+
+Export these registers on the emulated root bridge via new .read_ext() and
+.write_ext() methods.
+
+Note that in the Advanced Error Reporting Capability header the offset to
+the next Extended Capability header is set, but it is not documented in
+Armada 3700 Functional Specification. Since this change adds support only
+for Advanced Error Reporting, explicitly clear PCI_EXT_CAP_NEXT bits in AER
+capability header.
+
+Now the pcieport driver correctly detects AER support and allows PCIe AER
+driver to start receiving ERR interrupts. Kernel log now says:
+
+ pcieport 0000:00:00.0: AER: enabled with IRQ 52

+ interrupt
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add support for Data Link Layer State Change in the emulated slot
+registers and hotplug interrupt via the emulated root bridge.
+
+This is mainly useful for when an error causes link down event. With
+this change, drivers can try recovery.
+
+Link down state change can be implemented because Aardvark supports Link
+Down event interrupt. Use it for signaling that Data Link Layer Link is
+not active anymore via Hot-Plug Interrupt on emulated root bridge.
+
+Link up interrupt is not available on Aardvark, but we check for whether
+link is up in the advk_pcie_link_up() function. By triggering Hot-Plug
+Interrupt from this function we achieve Link up event, so long as the
+function is called (which it is after probe and when rescanning).
+Although it is not ideal, it is better than nothing.
+
+Since advk_pcie_link_up() is not called from interrupt handler, we
+cannot call generic_handle_domain_irq() from it directly. Instead create
+a TIMER_IRQSAFE timer and trigger it from advk_pcie_link_up().
+
+(We haven't been able to find any documentation for a Link Up interrupt
+ on Aardvark, but it is possible there is one, in some undocumented
+ register. If we manage to find this information, this can be
+ rewritten.)

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Emulate Slot PowerLimit Scale and Value bits in the Slot Capabilities
+register of the emulated bridge and if slot power limit value is
+defined, send that Set_Slot_Power_Limit message via Message Generation
+Control Register in Link Up handler on link up event.
+
+Slot power limit value is read from device-tree property
+'slot-power-limit-milliwatt'. If this property is not specified, we
+treat it as "Slot Capabilities register has not yet been initialized".
+
+According to PCIe Base specification 3.0, when transitioning from a
+non-DL_Up Status to a DL_Up Status, the Port must initiate the
+transmission of a Set_Slot_Power_Limit Message to the other component
+on the Link to convey the value programmed in the Slot Power Limit
+Scale and Value fields of the Slot Capabilities register. This
+transmission is optional if the Slot Capabilities register has not
+yet been initialized.

+
+This fix for ARM does not account ARCH_PFN_OFFSET for mem_map as later used by
+page_to_pfn anymore.
+
+The following output was generated with two hacked in printk statements:
+
+printk("before %p vs. %p or %p\n", mem_map, mem_map - offset, mem_map -
+(pgdat->node_start_pfn - ARCH_PFN_OFFSET));
+ if (page_to_pfn(mem_map) != pgdat->node_start_pfn)
+ mem_map -= offset + (pgdat->node_start_pfn - ARCH_PFN_OFFSET);
+printk("after %p\n", mem_map);
+
+Output:
+
+[ 0.000000] before 8861b280 vs. 8861b280 or 8851b280
+[ 0.000000] after 8851b280
+
+As seen in the first line mem_map with subtraction of offset does not equal the
+mem_map after subtraction of ARCH_PFN_OFFSET.
+
+After adding the offset of ARCH_PFN_OFFSET as well to mem_map as the
+previously calculated offset is zero for the named platform it is able to boot
+4.4 and 4.9-rc7 again.

+
+Currently there is no use for the interrupts on the rs5c372 RTC and the
+wakealarm isn't enabled. There are some devices like NASes which use this
+RTC to wake up from the power off state when the INTR pin is activated by
+the alarm clock.
+
+Enable the alarm and let to be used as a wakeup source.

+Tested on a Buffalo LS421DE NAS.

+Subject: [PATCH 45/96] mtd: spi-nor: write support for minor aligned
+ partitions
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Do not prevent writing to mtd partitions where a partition boundary sits
+on a minor erasesize boundary.
+This addresses a FIXME that has been present since the start of the
+linux git history:
+/* Doesn't start on a boundary of major erase size */
+/* FIXME: Let it be writable if it is on a boundary of
+ * _minor_ erase size though */
+
+Allow a uniform erase region spi-nor device to be configured
+to use the non-uniform erase regions code path for an erase with:
+CONFIG_MTD_SPI_NOR_USE_VARIABLE_ERASE=y
+
+On supporting hardware (SECT_4K: majority of current SPI-NOR device)
+provide the facility for an erase to use the least number
+of SPI-NOR operations, as well as access to 4K erase without
+requiring CONFIG_MTD_SPI_NOR_USE_4K_SECTORS
+
+Introduce erasesize_minor to the mtd struct,
+the smallest erasesize supported by the device
+
+On existing devices, this is useful where write support is wanted
+for data on a 4K partition, such as some u-boot-env partitions,
+or RouterBoot soft_config, while still netting the performance
+benefits of using 64K sectors
+
+Performance:
+time mtd erase firmware
+OpenWrt 5.10 ramips MT7621 w25q128jv 0xfc0000 partition length

++ MyLoader is a bootloader which allows the user to define partitions
++ in flash devices, by putting a table in the second erase block
++ on the device, similar to a partition table. This table gives the

++
++ If you need code which can detect and parse these tables, and
++ register MTD 'partitions' corresponding to each image detected,
++ enable this option.
++
++ You will still need the parsing functions to be called by the driver
++ for your particular device. It won't happen automatically.

+Subject: [PATCH 50/96] kernel: disable cfi cmdset 0002 erase suspend
+
+on some platforms, erase suspend leads to data corruption and lockups when write
+ops collide with erase ops. this has been observed on the buffalo wzr-hp-g300nh.
+rather than play whack-a-mole with a hard to reproduce issue on a variety of devices,
+simply disable erase suspend, as it will usually not produce any useful gain on
+the small filesystems used on embedded hardware.

+
+This patch adds support for ESMT F50L1G41LB and F50D1G41LB.
+It seems that ESMT likes to use random JEDEC ID from other vendors.
+Their 1G chips uses 0xc8 from GigaDevice and 2G/4G chips uses 0x2c from
+Micron. For this reason, the ESMT entry is named esmt_c8 with explicit
+JEDEC ID in variable name.
+
+Datasheets:

+Subject: [PATCH 56/96] mtd: mtdconcat: add dt driver for concat devices
+
+Some mtd drivers like physmap variants have support for concatenating
+multiple mtd devices, but there is no generic way to define such a
+concat device from within the device tree.
+
+This is useful for some SoC boards that use multiple flash chips as
+memory banks of a single mtd device, with partitions spanning chip
+borders.
+
+This commit adds a driver for creating virtual mtd-concat devices. They
+must have a compatible = "mtd-concat" line, and define a list of devices
+to concat in the 'devices' property, for example:
+
+flash {
+ compatible = "mtd-concat";
+
+ devices = <&flash0 &flash1>;
+
+ partitions {
+ ...
+ };
+};
+
+The driver is added to the very end of the mtd Makefile to increase the
+likelyhood of all child devices already being loaded at the time of
+probing, preventing unnecessary deferred probes.

+Subject: [PATCH 64/96] net_sched/codel: do not defer queue length update
+
+When codel wants to drop last packet in ->dequeue() it cannot call
+qdisc_tree_reduce_backlog() right away - it will notify parent qdisc
+about zero qlen and HTB/HFSC will deactivate class. The same class will
+be deactivated second time by caller of ->dequeue(). Currently codel and
+fq_codel defer update. This triggers warning in HFSC when it's qlen != 0
+but there is no active classes.
+
+This patch update parent queue length immediately: just temporary increase
+qlen around qdisc_tree_reduce_backlog() to prevent first class deactivation
+if we have skb to return.
+
+This might open another problem in HFSC - now operation peek could fail and
+deactivate parent class.

+Subject: [PATCH 67/96] Add support for MAP-E FMRs (mesh mode)
+
+MAP-E FMRs (draft-ietf-softwire-map-10) are rules for IPv4-communication
+between MAP CEs (mesh mode) without the need to forward such data to a
+border relay. This is similar to how 6rd works but for IPv4 over IPv6.

+Subject: [PATCH 68/96] ipv6: allow rejecting with "source address failed
+ policy"
+
+RFC6204 L-14 requires rejecting traffic from invalid addresses with
+ICMPv6 Destination Unreachable, Code 5 (Source address failed ingress/
+egress policy) on the LAN side, so add an appropriate rule for that.

+Subject: [PATCH 70/96] of_net: add mac-address-increment support
+
+Lots of embedded devices use the mac-address of other interface
+extracted from nvmem cells and increments it by one or two. Add two
+bindings to integrate this and directly use the right mac-address for
+the interface. Some example are some routers that use the gmac
+mac-address stored in the art partition and increments it by one for the
+wifi. mac-address-increment-byte bindings is used to tell what byte of
+the mac-address has to be increased (if not defined the last byte is
+increased) and mac-address-increment tells how much the byte decided
+early has to be increased.

+Subject: [PATCH 71/96] of/of_net: write back netdev MAC-address to device-tree
+
+The label-mac logic relies on the mac-address property of a netdev
+devices of-node. However, the mac address can also be stored as a
+different property or read from e.g. an mtd device.
+
+Create this node when reading a mac-address from OF if it does not
+already exist and copy the mac-address used for the device to this
+property. This way, the MAC address can be accessed using procfs.

+ the subdevices
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+For bus devices to be fully usable it's required to set their DMA
+parameters.
+
+For years it has been missing and remained unnoticed because of
+mips_dma_alloc_coherent() silently handling the empty coherent_dma_mask.
+Kernel 4.19 came with a lot of DMA changes and caused a regression on
+the bcm47xx. Starting with the commit f8c55dc6e828 ("MIPS: use generic
+dma noncoherent ops for simple noncoherent platforms") DMA coherent
+allocations just fail. Example:
+[ 1.114914] bgmac_bcma bcma0:2: Allocation of TX ring 0x200 failed
+[ 1.121215] bgmac_bcma bcma0:2: Unable to alloc memory for DMA
+[ 1.127626] bgmac_bcma: probe of bcma0:2 failed with error -12
+[ 1.133838] bgmac_bcma: Broadcom 47xx GBit MAC driver loaded
+
+This change fixes above regression in addition to the MIPS bcm47xx
+commit 321c46b91550 ("MIPS: BCM47XX: Setup struct device for the SoC").
+
+It also fixes another *old* GPIO regression caused by a parent pointing
+to the NULL:
+[ 0.157054] missing gpiochip .dev parent pointer
+[ 0.157287] bcma: bus0: Error registering GPIO driver: -22
+introduced by the commit 74f4e0cc6108 ("bcma: switch GPIO portions to
+use GPIOLIB_IRQCHIP").
+
+Fixes: f8c55dc6e828 ("MIPS: use generic dma noncoherent ops for simple noncoherent platforms")

+Subject: [PATCH 77/96] gpio: gpio-cascade: add generic GPIO cascade
+
+Adds support for building cascades of GPIO lines. That is, it allows
+setups when there is one upstream line and multiple cascaded lines, out
+of which one can be chosen at a time. The status of the upstream line
+can be conveyed to the selected cascaded line or, vice versa, the status
+of the cascaded line can be conveyed to the upstream line.
+
+A multiplexer is being used to select, which cascaded GPIO line is being
+used at any given time.
+
+At the moment only input direction is supported. In future it should be
+possible to add support for output direction, too.

+Subject: [PATCH 82/96] PCI: aardvark: Make main irq_chip structure a static
+ driver structure
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Marc Zyngier says [1] that we should use struct irq_chip as a global
+static struct in the driver. Even though the structure currently
+contains a dynamic member (parent_device), Marc says [2] that he plans
+to kill it and make the structure completely static.
+
+We have already converted others irq_chip structures in this driver in
+this way, but we omitted this one because the .name member is
+dynamically created from device's name, and the name is displayed in
+sysfs, so changing it would break sysfs ABI.
+
+The rationale for changing the name (to "advk-INT") in spite of sysfs
+ABI, and thus allowing to convert to a static structure, is that after
+the other changes we made in this series, the IRQ chip is basically
+something different: it no logner generates ERR and PME interrupts (they
+are generated by emulated bridge's rp_irq_chip).

+Subject: [PATCH 85/96] PCI: aardvark: Implement workaround for PCIe Completion
+ Timeout
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Marvell Armada 3700 Functional Errata, Guidelines, and Restrictions
+document describes in erratum 3.12 PCIe Completion Timeout (Ref #: 251),
+that PCIe IP does not support a strong-ordered model for inbound posted vs.
+outbound completion.
+
+As a workaround for this erratum, DIS_ORD_CHK flag in Debug Mux Control
+register must be set. It disables the ordering check in the core between
+Completions and Posted requests received from the link.
+
+Marvell also suggests to do full memory barrier at the beginning of
+aardvark summary interrupt handler before calling interrupt handlers of
+endpoint drivers in order to minimize the risk for the race condition
+documented in the Erratum between the DMA done status reading and the
+completion of writing to the host memory.
+
+More details about this issue and suggested workarounds are in discussion:
+https://lore.kernel.org/linux-pci/BN9PR18MB425154FE5019DCAF2028A1D5DB8D9@BN9PR18MB4251.namprd18.prod.outlook.com/t/#u
+
+It was reported that enabling this workaround fixes instability issues and
+"Unhandled fault" errors when using 60 GHz WiFi 802.11ad card with Qualcomm
+QCA6335 chip under significant load which were caused by interrupt status
+stuck in the outbound CMPLT queue traced back to this erratum.
+
+This workaround fixes also kernel panic triggered after some minutes of
+usage 5 GHz WiFi 802.11ax card with Mediatek MT7915 chip:
+
+ Internal error: synchronous external abort: 96000210 [#1] SMP
+ Kernel panic - not syncing: Fatal exception in interrupt

+ to link/activity
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The marvell PHY driver changes the LED[0] pin function to "On - 1000
+Mbps Link, Off - Else".
+
+Turris Omnia expects that the function is "On - Link, Blink - Activity,
+Off - No link".
+
+Use the `marvell,reg-init` DT property to change the function.
+
+In the future, once netdev trigger will support HW offloading, we will
+be able to have this configured via the combination of PHY driver and
+leds-turris-omnia driver.
