Merge tag 'arm-fixes-6.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull SoC fixes from Arnd Bergmann:
"A number of devicetree fixes came in for the rockchip platforms,
correcting some of the address information, and reverting a change to
the MMC controller configuration that caused regressions.
Four drivers have one code change each, addressing minor build issues
for the optee firmware driver, the litex SoC platform driver and two
reset drivers.
The riscv fixes as also simple, mainly turning off device nodes in the
canaan dts files unless they are actually usable on a particular
board.
Finally, Drew takes over maintaining the THEAD RISC-V SoC platform"

- The addressing uses DEVNAME of the physical serial port
- device, followed by the serial core controller instance,
- and the serial port instance. The options are the same
- as documented for the ttyS addressing above.
-
- The mapping of the serial ports to the tty instances
- can be viewed with:
-
- $ ls -d /sys/bus/serial-base/devices/*:*.*/tty/*
- /sys/bus/serial-base/devices/00:04:0.0/tty/ttyS0
-
- In the above example, the console can be addressed with
- console=00:04:0.0. Note that a console addressed this
- way will only get added when the related device driver
- is ready. The use of an earlycon parameter in addition to
- the console may be desired for console output early on.
