-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
-dts files.

-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: [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.

-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.

-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.
