Subject: [PATCH] arm64: dts: imx8mp: Enable HDMI on i.MX8MP DHCOM PDK2 and PDK3
Date: Tue, 14 May 2024 03:06:42 +0200
Message-ID: <20240514010706.245874-1-marex@denx.de>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Enable HDMI output on i.MX8MP DHCOM PDK2 and PDK3. The I2C5 on PDK2 and
I2C mux port 1 on PDK3 respectively are used in regular I2C mode instead
of HDMI DDC mode to permit connection of other I2C devices on those buses.
The pinctrl_hdmi node is part of the SoM DTSI already.
