Subject: [PATCH v2 08/26] clk: sun5i: add DRAM gates
Date: Thu, 14 Jan 2016 16:24:51 +0100	[thread overview]
Message-ID: <1452785109-6172-9-git-send-email-maxime.ripard@free-electrons.com> (raw)
In-Reply-To: <1452785109-6172-1-git-send-email-maxime.ripard@free-electrons.com>

The Allwinner SoCs have a gate controller to gate the access to the DRAM
clock to the some devices that need to access the DRAM directly (mostly
display / image related IPs).

Use a simple gates driver to support the one found in the A13 / R8 SoCs.
