Mark yao efd11cc8fa drm/rockchip: Correct vop out_mode configure
Force vop output mode on encoder driver seem not a good idea,

EDP, HDMI, DisplayPort all have 10bit input on rk3399,
On non-10bit vop, vop 8bit output bit[0-7] connect to the
encoder high 8bit [2-9].

So force RGB10 to RGB888 on vop driver would be better.

And another problem, EDP check crtc id on atomic_check,
but encoder maybe NULL, so out_mode configure would fail,
it cause edp no display.

Rob Herring ebc9446135 drm: convert drivers to use drm_of_find_panel_or_bridge
Similar to the previous commit, convert drivers open coding OF graph
parsing to use drm_of_find_panel_or_bridge instead.

This changes some error messages to debug messages (in the graph core).
Graph connections are often "no connects" depending on the particular
board, so we want to avoid spurious messages. Plus the kernel is not a
DT validator.

Tomeu Vizoso 0546d685f0 drm/rockchip: analogix_dp: Refuse to enable PSR if panel doesn't support it
There's no point in enabling PSR when the panel doesn't support it.

This also avoids a problem when PSR gets enabled when a CRTC is being
disabled, because sometimes in that situation the DSP_HOLD_VALID_INTR
interrupt on which we wait will never arrive. This was observed on
RK3288 with a panel without PSR (veyron-jaq Chromebook).

It's very easy to reproduce by running the kms_rmfb test in IGT a few
times.
