Subject: [PATCH] ARM: dts: imx6qdl-dhcom-pdk2: Fill in missing panel power-supply
Add missing panel power-supply property to DT to fix the following warning.
The power supply on this device is very simple chain of regulators from the
main 24V input, describe those.
"
arch/arm/boot/dts/nxp/imx/imx6q-dhcom-pdk2.dtb: panel: 'power-supply' is a required property
"
