X-Git-Tag: v6.3-rc1~202^2~45^2~290
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=582e7c1026fa848a918a1db159bcae7c5fa7f0ce;p=thirdparty%2Fkernel%2Flinux.git

arm64: dts: qcom: sm7225-fairphone-fp4: Add pmk8350 PMIC

The PMK8350 (which is actually a PMK8003) is used for the RTC and has
ADC for thermals.

Since the adc_tm compatible used in PMK8350 is not yet supported, skip
configuring that and the associated thermal zone for now.
