We continue to see a lot of new material. I've highlighted some of it
below, but there's been more beyond that as well.
One of the sweeping changes is that many boards have seen their ARM Mali
GPU devices added to device trees, since the DRM drivers have now been
merged.
So, with the caveat that I have surely missed several great
contributions, here's a collection of the material this time around:
New SoCs:
- Mediatek mt8183 (4x Cortex-A73 + 4x Cortex-A53)
- TI J721E (2x Cortex-A72 + 3x Cortex-R5F + 3 DSPs + MMA)
- Amlogic G12B (4x Cortex-A73 + 2x Cortex-A53)
New Boards / platforms:
- Aspeed BMC support for a number of new server platforms
- Kontron SMARC SoM (several i.MX6 versions)
- Novtech's Meerkat96 (i.MX7)
- ST Micro Avenger96 board
- Hardkernel ODROID-N2 (Amlogic G12B)
- Purism Librem5 devkit (i.MX8MQ)
- Google Cheza (Qualcomm SDM845)
- Qualcomm Dragonboard 845c (Qualcomm SDM845)
- Hugsun X99 TV Box (Rockchip RK3399)
- Khadas Edge/Edge-V/Captain (Rockchip RK3399)
Updated / expanded boards and platforms:
- Renesas r7s9210 has a lot of new peripherals added
- Polish and fixes for Rockchip-based Chromebooks
- Amlogic G12A has a lot of peripherals added
- Nvidia Jetson Nano sees various fixes and improvements, and is now at
feature parity with TX1

To support Rx in-band wakeup, one must create an interrupt specifier with
edge sensitivity on Rx pin and an addtional pinctrl to reconfigure Rx pin
to normal GPIO in sleep state. Driver will switch to sleep mode pinctrl and
enable irq wake before suspend and restore to default settings when
resuming.

Changed by Stefan:
Only call mctrl_gpio_init(), if the device has no ACPI companion device
to not break existing ACPI based systems. Also only use the mctrl_gpio_
functions when "gpios" is available.
Use MSR / MCR <-> TIOCM wrapper functions.

Convert the arm,pl011 binding to DT schema using json-schema.
The zte,zx296702-uart binding appears to be broken as the dts files are
missing 'arm,primecell'. That's included in the schema here to throw a
warning.

A few updates that we merged late but are low risk for regressions for
other platforms (and a few other straggling patches):
- I mis-tagged the 'drivers' branch, and missed 3 patches. Merged in
here. They're for a driver for the PL353 SRAM controller and a build
fix for the qualcomm scm driver.
- A new platform, RDA Micro RDA8810PL (Cortex-A5 w/ integrated Vivante
GPU, 256MB RAM, Wifi). This includes some acked platform-specific
drivers (serial, etc). This also include DTs for two boards with this
SoC, OrangePi 2G and OrangePi i86.
- i.MX8 is another new platform (NXP, 4x Cortex-A53 + Cortex-M4, 4K
video playback offload). This is the first i.MX 64-bit SoC.
- Some minor updates to Samsung boards (adding a few peripherals in
DTs).
- Small rework for SMP bootup on STi platforms.
- A couple of TEE driver fixes.
- A couple of new config options (bcm2835 thermal, Uniphier MDMAC)
enabled in defconfigs.

When a serial port continuously experiences input overrun from
(1) continuous receive characters from remote and or (2) hardware
issues, its interrupt handler can preempt other tasks especially
when the system is busy (ie. boot up period). This can cause other
tasks to get starved of processing time from the CPU.
When this dts binding is enabled and input overrun on the serial port
is detected, serial port receive will be throttled to give some breathing
room for processing other tasks. Value provided will be in milliseconds.

overrun-throttle-ms = <500>;

dictionary.com refers to the word as "Chiefly British", which is

The FIFO size of the UART devices is 64 on almost all UniPhier SoCs
with the exception Pro4TV SoC (MN2WS0235), which used 128 FIFO size.
However, Pro4TV SoC was never upstreamed, and out of production.
So, this property has never been used in a useful way.
Let's remove old unused code.
