Hi Sebastian,

This updates the existing omapdrm DSI code, so that it uses common drm_mipi_dsi API and drm_panel.

The patchset has been tested with Droid 4 using Linux console, X.org and Weston. The patchset is based on Laurent Pinchartl's patch series [0] and removes the last custom panel driver, so quite a few cleanups on the omapdrm codebase were possible.

[0] [PATCH v7 00/54] drm/omap: Replace custom display drivers with drm_bridge and drm_panel https://lore.kernel.org/dri-devel/20200222150106.22919-1-laurent.pinchart@id... git://linuxtv.org/pinchartl/media.git omapdrm/bridge/devel

I pushed this patchset into the following branch:

git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-n900.git omapdrm/bridge/devel-with-dsi

The previous version of this patchset has been sent quite some time ago. This version has been rebased and required cleaning up most of the hacks. I do not have a detailed changelog, but quite a few things changed. I decided against doing anything special for the DT change (adding DSI channel number), since only 3 devices are affected. It is quite likely, that all developers of those devices update DT together with kernel for those devices. My suggestion is to merge the first two patches ASAP and backport to stable, since it does not affect old kernels and the change is rather small.

RFCv1: https://lore.kernel.org/dri-devel/20191117023946.VjCC3yE08DMx7JIKxNagPoT5et7...

is there something new for this series? Is there a repo where it has been rebased to v5.8-rc1 (and tested)?

Our Pyra MIPI/DSI omap5 panel setup is broken by upstream changes since v5.7-rc1 and I am not sure if it is better to search in the old omapdrm code what is missing now. Or to wait for your DSI code and just update/fix our panel driver (and have a chance to get that one upstream).

BR and thanks, Nikolaus
