Sorry, I forgot to add that the description above could be reworded
a bit, e.g. not to repeat what's already visible in the patch itself.

For example:

     Designate the RK806 PMIC on the Radxa ROCK 5A as the system power
     controller, so the board shuts down properly on poweroff(8).

The patch subject could also be tweaked a bit, e.g. to refer to the
board as "Radxa ROCK 5A".
