From e30f56800e69db6d2763a1f7f64dfcc79f9b5ea7 Mon Sep 17 00:00:00 2001 From: Fabrizio Castro Date: Wed, 11 Mar 2020 20:03:40 +0000 Subject: arm64: dts: renesas: Add HiHope RZ/G2M board with idk-1110wr display The HiHope RZ/G2M is advertised as compatible with panel idk-1110wr from Advantech, however the panel isn't sold alongside the board. A new dts, adding everything that's required to get the panel to work with HiHope RZ/G2M, is the most convenient way to support the HiHope RZ/G2M when it's connected to the idk-1110wr.
