Subject: [PATCH v2 09/18] ARM: dts: imx6q-apalis: Add LVDS panel support
Date:   Wed, 15 Jun 2022 13:49:57 +0200

From: Oleksandr Suvorov <oleksandr.suvorov@toradex.com>

Add LVDS panel and endpoint linkage support but keep the inherited
disabled state. This allows to enable it in an overlay per the current
system configuration.
