[PATCH 1/1] arm: dts: owl-s500-roseapplepi: Add ATC2603C PMIC

2021-03-12T10:32:12Z

Add device tree node for ATC2603C PMIC and remove the 'fixed-3.1V'
dummy regulator used for the uSD supply.

Additionally, add 'SYSPWR' fixed regulator and provide cpu0 supply.

Please note the patch depends on the ATC260x PMIC support which is queued
for merging in v5.13:
