| |
Downstream defines four ADC channels related to thermal sensors external to the PM8998 and two channels for internal voltage measurements.
Add these to the upstream SDM845 MTP, describe the thermal monitor channels and add thermal_zones for these.
Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> ---
In addition to the iio channels exposed by v1, Daniel wanted thermal_zones...
Changes since v1: - Enable the pm8998_adc_tm and describe the ADC channels - Add thermal-zones for the new channels
