Subject: [PATCH 0/4] RK3588 and Rock 5B dts additions: thermal, OPP, rfkill
 and fan

This is an assortment of device tree additions for RK3588(s) and their
enablement on Radxa Rock5B.

Thermal zone information and cooling maps is the follow-up to feedback
received on v2 patch version [1] - thanks a lot to Dragan, Heiko and
Daniel for review and comments. The patch adds passive cooling maps
for the three separate CPU clusters found in RK3588, as well as
critical trips for all TSADC channels. Enablement on Rock 5B was
split out to a separate patch, where I also add active cooling via
the PWM fan optionally available there. Other changes from v2:
 - Zero hysteresis for critical trips, per Daniel's guidance
 - Zero 'polling-delay' for zones having no active cooling maps,
   given that the driver supports interrupts for crossing trip
   temperature and thus doesn't need polling there, per Daniel's
   guidance
 - Zero 'polling-delay-passive' for zones having no passive cooling,
   per Daniel's guidance
 - Extra passive cooling alerts before the control temperature
   to enable power allocation governor's PID parameters
   initialization, per Daniel's guidance
 - Renamed the thermal zone tracking the middle of the chip
   to package_thermal, per Dragan's guidance

OPPs help actually scale CPU frequencies up and down for both cooling
and performance - tested on Rock 5B under varied loads.

RFKILL patch is the same one sent earlier just before the merge window
opened [2]. It didn't get any feedback back then, so I'm just
resending it here for ease of reference. Tested on Rock 5B with an
Intel AX210 card.
