Subject: [PATCH v4 12/19] ARM: sun8i-a33: Add SRAM controller node and C1 SRAM region
Date: Mon, 18 Jun 2018 16:58:36 +0200
Message-Id: <20180618145843.14631-13-paul.kocialkowski@bootlin.com>

Sender: linux-media-owner@vger.kernel.org
List-ID: <linux-media.vger.kernel.org>

From: Maxime Ripard <maxime.ripard@bootlin.com>

This adds a SRAM controller node for the A33, with support for the C1
SRAM region that is shared between the Video Engine and the CPU.
