[PATCH v2 8/8] drm/ssd130x: Switch preferred_bpp/depth to 1

From: Geert Uytterhoeven
Date: Thu Aug 24 2023 - 11:09:38 EST


The native display format is R1. Hence change the preferred_depth and
preferred_bpp to 1, to avoid the overhead of using XR24 and the
associated conversions when using fbdev emulation and its text console.
