[PATCH v3 6/6] drm/rockchip: cdn-dp: remove the DP phy switch

2018-02-16 Thread Enric Balletbo i Serra
From: Chris Zhong There are 2 Type-c PHYs in RK3399, but only one DP controller. Hence only one PHY can connect to DP controller at one time, the other should be disconnected. The GRF_SOC_CON26 register has a switch bit to do it, set this bit means enable PHY 1, clear this bit means enable PHY 0.
