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I didn't get any reply for my comments and unfortunately the mail of Thierry Escande, who submitted that patchset is no longer valid, so I decided to resend the minimal patchset that fixes the issue with Chromebook2 Peach-Pit board, which was broken since v4.10 kernel release.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