[PATCH v2 08/26] clk: sun5i: add DRAM gates
From: Maxime Ripard <hidden>
Date: 2016-01-14 15:27:58
Also in:
dri-devel, linux-clk, linux-devicetree, lkml
Subsystem:
arm/allwinner soc clock support, common clk framework, open firmware and flattened device tree bindings, the rest · Maintainers:
Emilio López, Michael Turquette, Stephen Boyd, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
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.
