Subject: [PATCH] arm64: dts: allwinner: a64: Add device node for Mali-400 GPU
Date: Tue, 23 Oct 2018 21:42:03 +0530	[thread overview]
Message-ID: <20181023161203.2956-1-jagan@amarulasolutions.com> (raw)

Add support for Allwinner A64 has Mali-400MP2.

All interrupt lines are mentioned in the manual so used the same.
Used 408MHz as assigned clock rate used by BSP, so used the same as
well.
