Subject: [PATCH] arm64: dts: imx8mp-evk: Add MX8-DLVDS-LCD1 display module support
Date: Wed, 8 May 2024 18:00:13 +0800 [thread overview]
Message-ID: <20240508100013.2693440-1-victor.liu@nxp.com> (raw)
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.MX8MP EVK.
Specify 148.5MHz clock frequency in panel-timing node to accommodate
3.5-fold 519.75MHz media_ldb clock which is derived from 1.0395GHz
video_pll1 clock.
