Subject: [RESEND PATCH] drm/tilcdc: fix raster control register setting
Date: Tue, 16 Feb 2021 21:22:25 +0100	[thread overview]
Message-ID: <20210216202225.12861-1-dariobin@libero.it> (raw)

The fdd property of the tilcdc_panel_info structure must set the reqdly
bit field  (bit 12 to 19) of the raster control register. The previous
statement set the least significant bit instead.
