u-boot 2022.07 successfully finds and loads kernel (5.18.3) on my
Pinebook Pro however boot process fails when loading rk808 module:
rk3x-i2c ff3c0000.i2c: timeout, ipd: 0x00, state: 1
rk808 0-001b: failed to read the chip id at 0x17
rk808: probe of 0-001b failed with error -110

power: pmic: rk8xx: Support sysreset shutdown method
Add support for sysreset shutdown for this PMIC. The values were pulled
from the various datasheets, but for now it has only been tested on
the rk817 (for an Odroid Go Advance).
