[PATCH 06/31] ARM: shmobile: r8a7790: Add IRQC clock to device tree
From: Simon Horman <hidden>
Date: 2015-05-14 01:06:35
Also in:
linux-sh
Subsystem:
common clk framework, open firmware and flattened device tree bindings, the rest · Maintainers:
Stephen Boyd, Brian Masney, Jerome Brunet, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
From: Geert Uytterhoeven <geert+renesas@glider.be> Link the external IRQ controller irqc0 to the IRQC module clock, so it can be power managed using that clock.
