Subject: [PATCH v2 1/3] ARM: dts: stm32: Enable LVDS panel on i.Core STM32MP1 EDIMM2.2
Date: Fri, 12 Nov 2021 11:08:54 +0530	[thread overview]
Message-ID: <20211112053856.18412-1-jagan@amarulasolutions.com> (raw)

Engicam i.Core STM32MP1 EDIMM2.2 Starter Kit has plugged with
7" LVDS panel.

Engicam i.Core STM32MP1 SoM has SN65DSI84 DSI to LVDS bridge.

This patch adds a display pipeline to connect DSI to SN65DSI84
to 7" LVDS panel.
