Rocky,

å 2017å08æ24æ 18:27, Rocky Hao åé:
Add tsadc needed main information for RV1108 SoC.
750000Hz is the max clock rate supported by tsadc module.

From the Patch[4/5], you set the critial temperature is 95 degree. I will suggest the Tshut temperature is 100 degree.
Think about the the peripherial devices, the 120 degree will damage some chips.
