[PATCH v2 1/2] arm64: dts: imx8mm-evk: Add HDMI support

[Fabio Estevam]

From: Fabio Estevam <festevam@denx.de>

imx8mm-evk has a MIPI DSI port that can be used with a ADV7535 MIPI
DSI to HDMI bridge.

Add support for it.

[PATCH v2 2/2] arm64: defconfig: Enable the TI SN65DSI83 driver

[Fabio Estevam]

From: Fabio Estevam <festevam@denx.de>

There are some imx8mm-based boards that contain an SN65DSI83 MIPI
DSI to LVDS bridge chip.

Add support for it so that the LVDS output can be functional by default.
