Add support for vadc and adc-tm channels which are used for monitoring thermistors present on the platform. - Add the necessary includes for qcom,spmi-adc7-pm7325 and qcom,spmi-adc7-pmk8350. - Add thermal zones for quiet-thermal, sdm-skin-thermal, and xo-thermal, and define their polling delays and thermal sensors. - Configure the pm7325_temp_alarm node to use the pmk8350_vadc channel for thermal monitoring. - Configure the pmk8350_adc_tm node to enable its thermal sensors and define their registers and settings. - Configure the pmk8350_vadc node to define its channels and settings Signed-off-by: Rakesh Kota <quic_kotarake@quicinc.com> --- Changes from V2: - As per Konrad Dybcio’s suggestion, removed all default polling values. Changes from V1: - Update the Die temp name to Channel as per Documentation. - As per Konrad Dybcio’s suggestion, I have sorted the pmk8350_adc_tm channels by unit address instead of alphabetically. --- arch/arm64/boot/dts/qcom/qcs6490-rb3gen2.dts | 108 +++++++++++++++++++ 1 file changed, 108 insertions(+)
