Subject: [PATCH v3 0/4] arm64: dts: imx8mm-kontron: Add HDMI and LVDS display support

This add support for the display bridges (DSI->LVDS and DSI->HDMI)
on the BL i.MX8MM and the 7" LVDS panel in a separate overlay.

Only one of the interfaces (HDMI or LVDS) is supported at the same

* Patch 4: Add the LVDS panel overlay

Changes for v3:
* Add A-b tag from Krzysztof
* Fix LVDS bridge input port reference

Changes for v2:
* Patch 1: Add link to commit message
* Patch 2: Add Conors A-b tag
* Patch 3: Remove blank lines from hdmi node
* Patch 3: Fix order of lvds and hdmi nodes within i2c
* Patch 3: Remove the unneeded deletion of samsung,pll-clock-frequency
* Patch 3: Use the existing MIPI DSI output port from imx8mm.dtsi
* Patch 4: Update copyright year
* Patch 4: Use exisitng MIPI DSI output port from imx8mm.dtsi
* Patch 4: Fix pinctrl for GPIO hogs
* Patch 4: Fix property order in i2c2 node
* Patch 4: Use generic node name for touchscreen
