Pull more ARM SoC updates from Olof Johansson:
"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"

dt-bindings: serial: 8250: Add rate limit for serial port input overruns

2018-12-17T15:02:57+00:00

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.

&serial0{
	overrun-throttle-ms = <500>;
};

Documentation: Use "while" instead of "whilst"

2018-11-20T16:30:43+00:00

Whilst making an unrelated change to some Documentation, Linus sayeth:

  | Afaik, even in Britain, "whilst" is unusual and considered more
  | formal, and "while" is the common word.
  |
  | [...]
  |
  | Can we just admit that we work with computers, and we don't need to
  | use þe eald Englisc spelling of words that most of the world never
  | uses?

dictionary.com refers to the word as "Chiefly British", which is
probably an undesirable attribute for technical documentation.

Replace all occurrences under Documentation/ with "while".
