Subject: [PATCH v9 3/8] dt-bindings: display: Add ingenic,jz4780-dw-hdmi DT Schema
Date: Wed, 24 Nov 2021 22:29:09 +0100	[thread overview]
Message-ID: <d678e785d95487202ac0660eb66796e9fb5beb50.1637789354.git.hns@goldelico.com> (raw)
In-Reply-To: <cover.1637789354.git.hns@goldelico.com>

From: Sam Ravnborg <sam@ravnborg.org>

Add DT bindings for the hdmi driver for the Ingenic JZ4780 SoC.
Based on .txt binding from Zubair Lutfullah Kakakhel

We also add generic ddc-i2c-bus to synopsys,dw-hdmi.yaml
