Subject: [PATCH] reset: ath79: read back reset register
Read back the reset register in order to flush the cache. This fixes
spurious reboot hangs on TP-Link TL-WDR3600 and TL-WDR4300 with Zentel
DRAM chips.
This issue was fixed in the past, but switching to the reset-driver
specific implementation removed the old fix.

Subject: [PATCH 18/33] MIPS: pci-ar71xx: convert to OF
With the ath79 target getting converted to pure OF, we can drop all the
platform data code and add the missing OF bits to the driver. We also add
a irq domain for the PCI/e controllers cascade, thus making it usable from
dts files.

With the driver being converted from platform_data to pure OF, we need to

Subject: [PATCH 20/33] MIPS: pci-ar724x: convert to OF
With the ath79 target getting converted to pure OF, we can drop all the
platform data code and add the missing OF bits to the driver. We also add
a irq domain for the PCI/e controllers cascade, thus making it usable from
dts files.

Subject: MIPS: pci-ar724x: add QCA9550 reset sequence
The QCA9550 family of SoCs have a slightly different reset
sequence compared to older chips.
Normally the bootloader performs this sequence, however
some bootloader implementation expect the operating system
to clear the reset.
Also get the resets from OF to support handling of the second
PCIe root-complex on the QCA9558.

Subject: [PATCH] ath79: force SGMII SerDes mode to MAC operation
The mode on the SGMII SerDes on the QCA9563 is 1000 Base-X by default.
This only allows for 1000 Mbit/s links, however when used with an SGMII
PHY in 100 Mbit/s link mode, the link remains dead.
This strictly has nothing to do with the SerDes calibration, however it
is done at the same point in the QCA reference U-Boot which is the
blueprint for everything happening here. As the current state is more or
less a hack, this should be fine.
This fixes the issues outlined above on a TP-Link EAP-225 Outdoor.

From: Christian Lamparter <chunkeey@gmail.com>
Subject: [PATCH] ath79: port cybertan_part from ar71xx
This patch ports the cybertan_part code from ar71xx and converts the
driver to a DT-supported mtd parser. As a result, it will no longer
add the u-boot, nvram and art partitions, which were never part of
the special Cybertan header.
Instead these partitions have to be specified in the DT, which has the
upside of making it possible to add properties (i.e.: read-only), labels
and references to these important partitions.

Subject: [PATCH] phy/mdio-bitbang: prevent rescheduling during command
It seems some phys have some maximum timings for accessing the MDIO line,
resulting in bit errors under cpu stress. Prevent this from happening by
disabling interrupts when sending commands.

Subject: [PATCH] ath79: ar8216: make switch register access atomic
due to some unknown reason these register accesses sometimes fail
on the integrated switch without this patch.
THIS ONLY WORKS ON ATH79 AND MAY BREAK THE DRIVER ON OTHER PLATFORMS!
The mdio bus on ath79 works in polling mode and doesn't rely on
any interrupt. This patch breaks the driver on any mdio master
with interrupts used.

Subject: [PATCH] ath79: ignore the abused interrupt-map on pcie node
ath79 PCIe interrupt controller has stopped working correctly. This
is because the DT exposing a non-sensical interrupt-map property,
and their drivers relying on the kernel ignoring this property[1].
This patch fix the pcie init error:
ath9k 0000:00:00.0: of_irq_parse_pci: failed with rc=-14
Notice:
This is just a workaround, not a fix. PCIe driver and related dts
node need to be rewritten.

Subject: [PATCH] ath79: add Mikrotik rb4xx series drivers
This adds 3 Mikrotik rb4xx series drivers as follows:
rb4xx-cpld: This is in the mfd subsystem, and is the parent CPLD device
that interfaces between the SoC SPI bus and its two children below.
rb4xx-gpio: This is the GPIO expander.
rb4xx-nand: This is the NAND driver.
The history of this code comes in three phases.
1. The first is a May 2015 attempt to push the equivalient ar71xx rb4xx
drivers upstream. See https://lore.kernel.org/patchwork/patch/940880/.
Module-author: Gabor Juhos <juhosg@openwrt.org>
Module-author: Imre Kaloz <kaloz@openwrt.org>
Module-author: Bert Vermeulen <bert@biot.com>
2. Next several ar71xx patches were applied bringing the code current.

commit 7c09fa4a7492ca436f2c94bd9a465b7c5bbeed6f
Submitted-by: Felix Fietkau <nbd@nbd.name>
3. Finally a heavy refactor to split the driver into the three new
subsystems, and updated to work with the device tree configuration, plus
updates and review feedback incorporated

From: Denis Kalashnikov <denis281089@gmail.com>
Subject: [PATCH] ath79: add support for reset key on MikroTik RB912UAG-2HPnD
On MikroTik RB91x board series a reset key shares SoC gpio
line #15 with NAND ALE and NAND IO7. So we need a custom
gpio driver to manage this non-trivial connection schema.
Also rb91x-nand needs to have an ability to disable a polling
of the key while it works with NAND.
While we've been integrating rb91x-key into a firmware, we've
figured out that:
* In the gpio-latch driver we need to add a "cansleep" suffix to
several gpiolib calls,
* When gpio-latch and rb91x-nand fail to get a gpio and an error
is -EPROBE_DEFER, they shouldn't report about this, since this
actually is not an error and occurs when the gpio-latch probe
function is called before the rb91x-key probe.
We fix these related things here too.

From 81889eb2b37bc21df4ff259441e8fc12d4f27cd9 Mon Sep 17 00:00:00 2001
From: Linus Walleij <linus.walleij@linaro.org>
Date: Thu, 9 May 2024 08:48:31 +0200
Subject: [PATCH] net: ethernet: cortina: Locking fixes
This fixes a probably long standing problem in the Cortina
Gemini ethernet driver: there are some paths in the code
where the IRQ registers are written without taking the proper
locks.
Fixes: 4d5ae32f5e1e ("net: ethernet: Add a driver for Gemini gigabit ethernet")

Subject: [PATCH 1/2] compiler_types.h: Define __retain for
__attribute__((__retain__))
Some code includes the __used macro to prevent functions and data from
being optimized out. This macro implements __attribute__((__used__)), which
operates at the compiler and IR-level, and so still allows a linker to
remove objects intended to be kept.
Compilers supporting __attribute__((__retain__)) can address this gap by
setting the flag SHF_GNU_RETAIN on the section of a function/variable,
indicating to the linker the object should be retained. This attribute is
available since gcc 11, clang 13, and binutils 2.36.
Provide a __retain macro implementing __attribute__((__retain__)), whose
first user will be the '__bpf_kfunc' tag.

Subject: [PATCH 2/2] bpf: Harden __bpf_kfunc tag against linker kfunc removal
BPF kfuncs are often not directly referenced and may be inadvertently
removed by optimization steps during kernel builds, thus the __bpf_kfunc
tag mitigates against this removal by including the __used macro. However,
this macro alone does not prevent removal during linking, and may still
yield build warnings (e.g. on mips64el):
LD vmlinux
BTFIDS vmlinux

WARN: resolve_btfids: unresolved symbol bpf_lookup_user_key

NM System.map
SORTTAB vmlinux
OBJCOPY vmlinux.32
Update the __bpf_kfunc tag to better guard against linker optimization by
including the new __retain compiler macro, which fixes the warnings above.
Verify the __retain macro with readelf by checking object flags for 'R':
