[PATCH] arm64: rk3399: adjust vdd power layout

xiaobo peterwillcn at gmail.com
Thu Jul 1 09:17:52 CEST 2021


1. R4S passive silent heat dissipation based on metal housing,
   no active heat dissipation by fan, so PWM-Fan and CPU_Thermal are removed
2. Modify Ethernet1 interface of PCIE0
3. Modify the VCC VDD power layout
