[PATCH v12 4/5] ARM: dts: add main Thermal info to rk3288

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

 




This patch is depend on rk3288-thermal.dtsi,or
it will compile error.

If the temperature over a period of time High,over 120C
the resulting TSHUT gave CRU module,let it reset
the entire chip,or via GPIO give PMIC.
