[PATCH v2 2/3] arm64: dts: amlogic: a1: introduce cpu temperature sensor

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The A1 SoC family has only one thermal sensor for CPU temperature
measurement. It is required to set the TS clock rate to 500kHz to make
it workable.
