[PATCH v3 7/7] drm/vc4: dpi: Fix format mapping for RGB565

From: Maxime Ripard
Date: Thu Dec 01 2022 - 03:45:22 EST


From: Dave Stevenson <dave.stevenson@xxxxxxxxxxxxxxx>

The mapping is incorrect for RGB565_1X16 as it should be
DPI_FORMAT_18BIT_666_RGB_1 instead of DPI_FORMAT_18BIT_666_RGB_3.

Fixes: 08302c35b59d ("drm/vc4: Add DPI driver")
