Subject: MIPS: cmdline: Clean up boot_command_line initialization
Our current code to initialize boot_command_line is a mess. Some of this
is due to the addition of too many options over the years, and some of
this is due to workarounds for early_init_dt_scan_chosen() performing
actions specific to options from other architectures that probably
shouldn't be in generic code.
Clean this up by introducing a new bootcmdline_init() function that
simplifies the initialization somewhat. The major changes are:
- Because bootcmdline_init() is a function it can return early in the
CONFIG_CMDLINE_OVERRIDE case.
- We clear boot_command_line rather than inheriting whatever
early_init_dt_scan_chosen() may have left us. This means we no longer
need to set boot_command_line to a space character in an attempt to
prevent early_init_dt_scan_chosen() from copying CONFIG_CMDLINE into
boot_command_line without us knowing about it.
- Indirection via USE_PROM_CMDLINE, USE_DTB_CMDLINE, EXTEND_WITH_PROM &
BUILTIN_EXTEND_WITH_PROM macros is removed; they seemingly served only
to obfuscate the code.
- The logic is cleaner, clearer & commented.
Two minor drawbacks of this approach are:
1) We call of_scan_flat_dt(), which means we scan through the DT again.
The overhead is fairly minimal & shouldn't be noticeable.
2) cmdline_scan_chosen() duplicates a small amount of the logic from
early_init_dt_scan_chosen(). Alternatives might be to allow the
generic FDT code to keep & expose a copy of the arguments taken from
the /chosen node's bootargs property, or to introduce a function like
early_init_dt_scan_chosen() that retrieves them without modification
to handle CONFIG_CMDLINE. Neither of these sounds particularly
cleaner though, and this way we at least keep the extra work in
arch/mips.

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

Subject: [PATCH 33/33] spi: ath79: drop pdata support
The target is being converted to pure OF. We can therefore drop all of the
platform data code from the driver.

From 7e161c423a232ef7ddf6c11b09ebe471dd5a23cf Mon Sep 17 00:00:00 2001
From: Chuanhong Guo <gch981213@gmail.com>
Date: Wed, 5 Feb 2020 18:25:37 +0800
Subject: [PATCH v4 1/2] spi: add driver for ar934x spi controller
This patch adds driver for SPI controller found in Qualcomm Atheros
AR934x/QCA95xx SoCs.
This controller is a superset of the already supported qca,ar7100-spi.
Besides the bit-bang mode in spi-ath79.c, this new controller added
a new "shift register" mode, allowing faster spi operations.

Emulate half-duplex operation and use mctrl_gpio to add support for
RS485 tranceiver with transmit/receive switch hooked to RTS GPIO line.
This is needed to make use of the RS485 port found on Teltonika RUT955.

v2: use bool to indicate ongoing half-duplex send, use it afterwards
to decide whether we've just been in a send operation.

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: fix block protection clearing
The block protection bits of macronix do not match the implementation.
The chip has 3 BP bits. Bit 5 is actually the third BP but here the
5th bit is SR_TB. Therefore the patch adds SR_TB to the mask. In the
4.19er kernel the whole register was simply set to 0.
The wrong implementation did not remove the block protection. This led
to jffs2 errors in the form of:
"jffs2: Newly-erased block contained word 0x19852003 at offset 0x..."
This caused inconsistent memory and other errors.

From 66e584435ac0de6e0abeb6d7166fe4fe25d6bb73 Mon Sep 17 00:00:00 2001
From: Jonas Gorski <jogo@openwrt.org>
Date: Tue, 16 Jun 2015 13:15:08 +0200
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.
Signed-off-by: Jonas Gorski <jogo@openwrt.org>

From b3797d1a92afe97c173b00fdb7824cedba24eef0 Mon Sep 17 00:00:00 2001

Date: Sun, 20 Sep 2020 01:00:45 +0800
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.
