Subject: [PATCH v4 3/3] ARM64: dts: meson-gx: Add MALI nodes for GXBB and GXL
Date: Wed, 22 Mar 2017 11:18:55 +0100 [thread overview]
Message-ID: <1490177935-9646-4-git-send-email-narmstrong@baylibre.com> (raw)
In-Reply-To: <1490177935-9646-1-git-send-email-narmstrong@baylibre.com>
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.
Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>
