From 189f02826cf471241070fb6ae5848206c2218b67 Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Wed, 9 Aug 2017 16:56:24 +0800 Subject: dt-bindings: add binding for Allwinner A64 SRAM controller and SRAM C The display engine on Allwinner A64 wants to claim the SRAM C section. Add a SRAM controller compatible for A64, and a SRAM section compatible for its SRAM C.
