[PATCH 1/2] arm64: dts: imx8mp-tqma8mpql-mba8mp-ras314: Add LVDS device tree overlay

[Alexander Stein]

From: Martin Schmiedel <Martin.Schmiedel@tq-group.com>

This adds an overlay for the supported LVDS display tianma tm070jvhg33.
The LVDS interface is the same as for MBa8MPxL so the already existing
overlay can be reused on this platform.

[PATCH 2/2] arm64: dts: imx8mp-tqma8mpql-mba8mp-ras314: Add Raspberry Pi Camera V2 overlay

[Alexander Stein]

This overlay configures IMX219 MIPI-CSI-2 camera attached to ISP1.
Also add additional overlay both using LVDS display and camera.

Can we name the node clock-cam24m?

'reg' doesn't match unit address.
