Subject: [PATCH v2 2/2] arm64: dts: allwinner: a64: Add device node for Mali-400 GPU

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.

Signed-off-by: Jagan Teki <jagan@...rulasolutions.com>
---
Changes for v2:
- Drop assigned clock properties
- Separate dt-bindings as separate patch.
