[PATCH v2 1/5] drm/bridge: samsung-dsim: add more mipi-dsi device debug information

From: Michael Tretter
Date: Fri Oct 06 2023 - 11:07:33 EST


From: Marco Felsch <m.felsch@xxxxxxxxxxxxxx>

Since the MIPI configuration can be changed on demand it is very useful
to print more MIPI settings during the MIPI device attach step.
