Subject: [PATCH v1] arm64: dts: freescale: imx8mp-verdin: add HDMI support
From: Francesco Dolcini <francesco.dolcini@...adex.com>
Enable HDMI output on Verdin iMX8MP on all the supported carrier boards
(dev, dahlia, mallow and yavia).
HDMI DDC I2C is used in regular I2C mode, see link on the related
dt-bindings patch.
Fix CEC and HPD pinctrl, having a pull-down on HPD and a pull-up on CEC.
