[PATCH v6 00/10] rockchip: kevin: Enable edp display

[PATCH v6 00/10] rockchip: kevin: Enable edp display

[Jeffy Chen]

Make edp display works on chromebook kevin(at least for boot animation).

Also solve some issues i meet during the bringup.

Changes in v6:
Don't change order of rockchip_drm_psr_register().

Changes in v5:
Call the destroy hook in the error handling path like in unbind().
Call the destroy hook in the error handling path like in unbind().
Update cleanup order in unbind().
Add disable to unbind(), and inline clk_prepare_enable() with bind().

Jeffy Chen (10):
  arm64: dts: rockchip: Enable edp disaplay on kevin
  drm/rockchip: analogix_dp: Remove unnecessary init code
  drm/bridge: analogix: Do not use device's drvdata

applied for 4.16 with Enric's Tested-tag and after also
seeing a bit of output on the edp.

Hi Jeffy,
I've pushed 2/10. Once you fix 3/10, I can push 3-7. I'd like someone familiar
with synopsys to review 8-9 before pushing those. Since 10 depends on 9, it'll
be blocked on synopsys review.

As I was just looking at the edp dts change in patch1 again, does this
series also contain a fix for the issue below [0] ?

I'm still seeing this on 4.14-rc6 with the most recent drm tree merged in.

There is a patch in the ML sent by Emil [1], similar to the Sean
patch, that solves the issue.

And I can confirm that the Jeffy's patches + Emil patch makes the
display work on kevin or current rc8
