Subject: [PATCH 1/7] drivers/video/rockchip/rk_vop.c: Use endpoint compatible
string to find VOP mode
The current code is using an hard coded enum and the of node reg value of
endpoint to find out if the endpoint is mipi/hdmi/lvds/edp/dp. The order
is different between rk3288, rk3399 vop little, rk3399 vop big.
A possible solution would be to make sure that the rk3288.dtsi and
rk3399.dtsi files have "expected" reg value or an other solution is
to find the kind of endpoint by comparing the endpoint compatible value.
This patch is implementing the more flexible second solution.

Subject: [PATCH 2/7] drivers/video/rockchip/rk_edp.c: Add rk3399 support
According to linux commit "drm/rockchip: analogix_dp: add rk3399 eDP
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
register on each IP.
The clocks don't seem to be the same, the eDP clock is not at index 1
on rk3399, so don't try changing the clock at index 1 to rate 0 on
rk3399.

Subject: [PATCH 4/7] PBP: Fix panel reset
On warm reset, the pinebook pro panel is not working correctly.
The issue is not yet debugged so, for now, this hack seems to be
enough. It toggles the GPIO1_C6 gpio [ LCDVCC_EN signal in the
schematics ] used by the vcc3v3_panel regulator.
There's no gpio_request, since the gpio is already in use at this
stage, so it can only fail.
