Subject: [PATCH 2/7] ARM: dts: qcom: Add PM8941 functions device nodes
Add configuration nodes for following devices:
* GPIO block, with 36 pins
* MPP block, with 8 pins
* Current ADC (IADC)
* Volatage ADC (VADC), with multiple inputs
* Thermal sensor device, which is using on chip VADC
channel report PMIC die temperature
* Power key device, which is responsible for clean system
reboot or shutdown
* White LED device
* RTC device
