Subject: [PATCH v2 1/2] arm64: dts/ti: am65x: Add Rocktech OLDI panel DT overlay
Date: Wed, 26 Apr 2023 11:36:11 +0530 [thread overview]
Message-ID: <20230426060612.19271-2-a-bhatia1@ti.com> (raw)
In-Reply-To: <20230426060612.19271-1-a-bhatia1@ti.com>
From: Jyri Sarha <jsarha@ti.com>
The OLDI-LCD1EVM add on board has Rocktech RK101II01D-CT panel[1] with
integrated touch screen. The integrated touch screen is Goodix GT928.
Add DT nodes for these and connect the endpoint nodes with DSS.
