From bb51b5350d2fe38f30f8e416541f32dde195d7d8 Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Tue, 22 Nov 2016 11:00:45 +0100 Subject: ARM64: dts: Add support for Meson GXM Following the Amlogic Linux kernel, it seem the only differences between the GXL and GXM SoCs are the CPU Clusters. This commit renames the gxl-s905d-p23x DTSI in a common file for S905D p23x and S912 q20x boards. Then adds a meson-gxm dtsi and reproduce the P23x to Q20x boards dts files since the S905D and S912 SoCs shares the same pinout and the P23x and Q20x boards are identical.
