[PATCH 1/2] ARM: dts: sun4i: Add support for the C1 SRAM region with the SRAM controller

From: Paul Kocialkowski
Date: Fri Jan 18 2019 - 10:00:40 EST


This adds support for the C1 SRAM region (to be used with the SRAM
controller driver) for the A10 platform. The region is shared
between the Video Engine and the CPU.
