Subject: [PATCH v2] ARM: dts: imx: Add missing LVDS decoder on M53Menlo
Date: Sun, 6 Feb 2022 23:11:23 +0100 [thread overview]
Message-ID: <20220206221123.284313-1-marex@denx.de> (raw)
The M53Menlo display unit uses an LVDS-to-DPI bridge, TI DS90CF364A.
Describe this bridge in DT, otherwise the DT incorrectly describes
DPI panel attached directly to LVDS source.
Fixes: 716be61d1869 ("ARM: dts: imx53: Add Menlosystems M53 board")
