Hi!

Last week I was asked to comment a patch "[PATCH v3 05/43] drm/bridge:
analogix_dp: Don't power bridge in analogix_dp_bind":
https://patchwork.kernel.org/patch/10193493/

That patch does almost the opposite to my initial fix "[PATCH v2]
drm/bridge: analogix_dp: Keep PHY powered between driver bind/unbind":
https://patchwork.kernel.org/patch/10242493/

I did some further investigation based on the proposed "[PATCH v3 00/43] DRM
Rockchip rk3399 (Kevin)" patchset:
https://lists.freedesktop.org/archives/dri-devel/2018-March/167775.html

Those patches seems to solve also some issues with analogix_dp driver on
Exynos5420 based Chromebook2 Peach-PIT board.

I didn't get any reply for my comments and unfortunately the mail of
Thierry Escande, who submitted that patchset is no longer valid, so I
decided to resend the minimal patchset that fixes the issue with
Chromebook2 Peach-Pit board, which was broken since v4.10 kernel release.

If possible, please apply them as fixes for v4.16-rc.

This patchset replaces my previous fix:
https://patchwork.kernel.org/patch/10242493/

Applied to drm-misc-next.

Could not apply to drm-misc-fixes since patchset depends on patches from
drm-misc-next.
