From 1f1f5183981d70bf0950f8467772851a05eb9148 Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Wed, 11 Apr 2018 22:16:41 +0800 Subject: [PATCH] arm64: dts: allwinner: a64: add SRAM controller device tree node Allwinner A64 has a SRAM controller, and in the device tree currently we have a syscon node to enable EMAC driver to access the EMAC clock register. As SRAM controller driver can now export regmap for this register, replace the syscon node to the SRAM controller device node, and let EMAC driver to acquire its EMAC clock regmap.
