Subject: [DO NOT MERGE PATCH v2 16/16] arm64: dts: imx8qxp-mek: Add MX8-DLVDS-LCD1 display module support
MX8-DLVDS-LCD1 display module integrates a KOE TX26D202VM0BWA LCD panel
and a touch IC. Add an overlay to support the LCD panel on i.MX8qxp
MEK. mipi_lvds_0_ldb channel0 and mipi_lvds_1_ldb channel1 send odd
and even pixels to the panel respectively.
Signed-off-by: Liu Ying <victor.liu@....com>
