Subject: [PATCH] drm/msm/dsi: remove bpc > 8 entries from allow list
Date: Fri, 6 Mar 2026 17:25:00 +0800 [thread overview]
Message-ID: <20260306092518.37849-1-mitltlatltl@gmail.com> (raw)
In upstream the msm, for bpc greater than 8 are not supported yet,
although the hardware block supports this. Remove them until we
support them.
Fixes: b0e71c2637d1 ("drm/msm/dsi: Allow values of 10 and 12 for bits per component")
