[PATCH v7 3/5] arm64: dts: imx8mp-skov-revc: convert to overlays

From: Steffen Trumtrar

Date: Mon Jul 27 2026 - 13:42:56 EST

The i.MX8MP Skov RevC jutouch 10" and Tian 7" variants are pretty
similar, apart from the Display and touch controller.

Move the common bindings to imx8mp-skov-revc-touch.dts and convert both
variants to use overlays applied on this base version.
