From 57ef579878c3a9a168ce071a78982216338ba500 Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Wed, 22 Mar 2017 11:18:55 +0100 Subject: [PATCH] ARM64: dts: meson-gx: Add Mali nodes for GXBB and GXL The same Mali-450 MP3 GPU is present in the GXBB and GXL SoCs. The node is simply added in the meson-gxbb.dtsi file. For GXL, since a lot is shared with the GXM that has a Mali-T820 IP, this patch adds a new meson-gxl-mali.dtsi and is included in the SoC specific dtsi files.
