[PATCH 07/10] drm/msm/dsi: Switch the QCM2290-specific compatible to index autodetection

Konrad Dybcio konrad.dybcio at linaro.org
Sat Feb 11 11:51:07 UTC 2023


Now that the logic can handle multiple sets of registers, move
the QCM2290 to the common logic and mark it deprecated. This allows us
to remove a couple of structs, saving some memory.

Fixes: ee1f09678f14 ("drm/msm/dsi: Add support for qcm2290 dsi controller")
