Subject: [PATCH v3 1/8] dt-bindings: gpu: mali-midgard: Add resets property
Date: Wed, 17 Apr 2019 19:30:24 +0200	[thread overview]
Message-ID: <20190417173031.9920-2-peron.clem@gmail.com> (raw)
In-Reply-To: <20190417173031.9920-1-peron.clem@gmail.com>

From: Neil Armstrong <narmstrong@baylibre.com>

The Amlogic ARM Mali Midgard requires reset controls to power on and
software reset the GPU, adds these as optional in the bindings.

+Vendor-specific bindings
+------------------------

+The Mali GPU is integrated very differently from one SoC to

+to specify one more vendor-specific compatible, among:
