This patch add ADC(Analog to Digital Converter)'s dt data to get raw data
with IIO subsystem. Usually, ADC is used to check temperature, jack type, and
so on.
Register map
- <0x126C0000 0x100> : ADC register's base address
- <0x10020718 0x4> : ADC_PHY_CONTROL, TS-ADC control register address
Clock
- <&clock 326> : ADC clock (clock name :'tsadc')
Interrupt
- INTG10[3] : ADC for General ADC
