The tcpc power domain will try to power up/down the power of Type-C PHY. Hence, we need control it in Type-C PHY driver with the pm_runtime helper. Signed-off-by: Chris Zhong <zyw@rock-chips.com> --- Changes in v2: None arch/arm64/boot/dts/rockchip/rk3399.dtsi | 2 ++ 1 file changed, 2 insertions(+)
