Subject: [PATCH v2 4/5] arm64: dts: Add DT node for the VIPNano-QI on the A311D
Date: Mon, 28 Nov 2022 12:17:37 +0100 [thread overview]
Message-ID: <20221128111740.39003-5-tomeu.vizoso@collabora.com> (raw)
In-Reply-To: <20221128111740.39003-1-tomeu.vizoso@collabora.com>
This "NPU" is very similar to the Vivante GPUs and Etnaviv works well
with it with just a few small changes.
v2: Add reference to RESET_NNA (Neil)
