Subject: [PATCH 2/4] drivers/video/rockchip/rk_edp.c: Add rk3399 support Subject: [PATCH 2/7] drivers/video/rockchip/rk_edp.c: Add rk3399 support
According to linux commit 82872e42bb1501dd9e60ca430f4bae45a469aa64, According to linux commit "drm/rockchip: analogix_dp: add rk3399 eDP
rk3288 and rk3399 eDP IPs are nearly the same, the difference is in the grf register support" (82872e42bb1501dd9e60ca430f4bae45a469aa64), rk3288 and rk3399
eDP IPs are nearly the same, the difference is in the grf register
(SOC_CON6 versus SOC_CON20). So, change the code to use the right (SOC_CON6 versus SOC_CON20). So, change the code to use the right
register on each IP. register on each IP.
The clocks don't seem to be the same, the eDP clock is not at index 1 on rk3399, The clocks don't seem to be the same, the eDP clock is not at index 1
so don't try changing the clock at index 1 to rate 0 on rk399. Also, enable all on rk3399, so don't try changing the clock at index 1 to rate 0 on
clocks, in case it's needed. rk3399.

has to be reserved, otherwise it may leads to kernel memory
overwrite.
