Hello,
The patch series "[PATCH v4 0/9] DRM panel drivers for omapdrm" added new DRM panel drivers for a set of panels used on OMAP platforms, with the omapdrm and omapfb2 drivers. Both those drivers contain omap-specific panel drivers, which the new DRM panel drivers aims to replace for omapdrm. The new drivers use the same module name as the old ones (with one exception), resulting in module name clashes.
This needs to be fixed separately for omapfb2 and omapdrm.
For omapfb2, we can disable the omapfb2-specific panel drivers in Kconfig when the standard drivers are enabled. As omapfb2 and omapdrm are mutually exclusive, the DRM panel drivers are not useful with omapfb2 in any case. This is done in patch 1/2.
For omapdrm, we can simply drop the omapdrm-specific panel drivers, as the new drivers replace them. This is done in patch 2/2, which was already part of the larger omapdrm patch series "[PATCH 00/60] drm/omap: Replace custom display drivers with drm_bridge and drm_panel".

Standard DRM panel drivers for several panels used by omapfb2 are now available. Their module name clashes with the modules from drivers/gpu/drm/omapdrm/displays/, part of the deprecated omapfb2 fbdev driver. As omapfb2 can only be compiled when the omapdrm driver is disabled, and the DRM panel drivers are useless in that case, make the omapfb2 panels depend on the standard DRM panels being disabled to fix the name clash.

I failed to convince myself they are equivalent.
From kconfig-languae.rst:
" '!' <expr> (6) (6) Returns the result of (2-/expr/).
An expression can have a value of 'n', 'm' or 'y' (or 0, 1, 2 respectively for calculations). A menu entry becomes visible when its expression evaluates to 'm' or 'y'. "
So !<SYMBOL> equals 1 for m and 0 for y. If I get it right.
My testing was not fully conclusive.
So I left it as is. Added a few Fixes: etc. tags. Applied and pushed to drm-misc-next.
Ohh, and dim came to my rescue. My Fixes: syntax was wrong but it was caught in my "dim push" - nice.

Hi Daniel
Ohh, and dim came to my rescue. My Fixes: syntax was wrong but it was caught in my "dim push" - nice.
Aside: dim fixes and dim cite should generate conformant commit citations.
Maybe I should invest more time in the wonders of dim. So far my use is limited to:
dim update-branches dim push dim apply dim add-missing-cc
But I can see dim has a bit more possibilities. Well, time to read some of the documentation.

Hello,
The patch series "[PATCH v4 0/9] DRM panel drivers for omapdrm" added new DRM panel drivers for a set of panels used on OMAP platforms, with the omapdrm and omapfb2 drivers. Both those drivers contain omap-specific panel drivers, which the new DRM panel drivers aims to replace for omapdrm. The new drivers use the same module name as the old ones (with one exception), resulting in module name clashes.
This needs to be fixed separately for omapfb2 and omapdrm.
For omapfb2, we can disable the omapfb2-specific panel drivers in Kconfig when the standard drivers are enabled. As omapfb2 and omapdrm are mutually exclusive, the DRM panel drivers are not useful with omapfb2 in any case. This is done in patch 1/2.
For omapdrm, we can simply drop the omapdrm-specific panel drivers, as the new drivers replace them. This is done in patch 2/2, which was already part of the larger omapdrm patch series "[PATCH 00/60] drm/omap: Replace custom display drivers with drm_bridge and drm_panel".
Laurent Pinchart (2): video: omapfb2: Make standard and custom panel drivers mutually exclusive drm/omap: displays: Remove unused panel drivers
Applied and pushed to drm-misc-next.
