-
-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 24/33] MIPS: ath79: make specifying the reference clock in DT
- optional
-
-It can be autodetected for many SoCs using the strapping options.
-If the clock is specified in DT, the autodetected value is ignored

-On AR934x, the MDIO reference clock can be configured to a fixed 100 MHz
-clock. If that feature is not used, it defaults to the main reference
-clock, like on all other SoC.

-Subject: [PATCH 29/33] MIPS: ath79: drop legacy pci code
-
-With the target now being fully OF based, we can drop the legacy pci
-platform code. The only bits that we need to keep is the fixup code
-which we move to its own code file.

-Subject: [PATCH 30/33] MIPS: ath79: drop platform device registration code
-
-With the target now being fully OF based, we can drop the legacy platform
-device registration code. All devices and their drivers are now probed
-via OF.

-Subject: [PATCH 31/33] MIPS: ath79: drop !OF clock code
-
-With the target now being fully OF based, we can drop the legacy clock
-registration code. All clocks are now probed via devicetree.

-Until upstream commit 6d4cd041f0af("net: phy: at803x: disable delay

-In addition, the TX delay setting is retained on soft-reset.

-This patch disables both delays on config init to align the behavior

-
-There are currently 1200+ instances of using platform_get_resource()
-and devm_ioremap_resource() together in the kernel tree.
-
-This patch wraps these two calls in a single helper. Thanks to that
-we don't have to declare a local variable for struct resource * and can
-omit the redundant argument for resource type. We also have one
-function call less.

-
-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.

-On AR934x this UART is usually not initialized by the bootloader
-as it is only used as a secondary serial port while the primary
-UART is a newly introduced NS16550-compatible.
-In order to make use of the ar933x-uart on AR934x without RTS/CTS
-hardware flow control, one needs to set the
-UART_CS_{RX,TX}_READY_ORIDE bits as other than on AR933x where this
-UART is used as primary/console, the bootloader on AR934x typically
-doesn't set those bits.
-Setting them explicitely on AR933x should not do any harm, so just
-set them unconditionally.

-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] mdio_bus: don't use managed reset-controller
-
-Geert Uytterhoeven reported that using devm_reset_controller_get leads
-to a WARNING when probing a reset-controlled PHY. This is because the
-device devm_reset_controller_get gets supplied is not actually the
-one being probed.
-
-Acquire an unmanaged reset-control as well as free the reset_control on
-unregister to fix this.

-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.

-From: Hauke Mehrtens <hauke@hauke-m.de>
-Date: Tue, 10 Nov 2015 22:18:39 +0100
-Subject: [RFC] serial: core: add support for boot console with arbitrary
- baud rates
-
-The Arduino Yun uses a baud rate of 250000 by default. The serial is
-going over the Atmel ATmega and is used to connect to this chip.
-Without this patch Linux wants to switch the console to 9600 Baud.
-
-With this patch Linux will use the configured baud rate and not a
-default one specified in uart_register_driver().
-
-Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
-[rebased to 4.14, slightly reworded commit message]
-Signed-off-by: Sungbo Eo <mans0n@gorani.run>
