[PATCH] irqchip: renesas-intc-irqpin: Add optional functional clock to bindings
From: Geert Uytterhoeven <geert+renesas@glider.be>
Date: 2015-03-18 16:37:45
Also in:
linux-devicetree, lkml
Subsystem:
irqchip drivers, open firmware and flattened device tree bindings, the rest · Maintainers:
Thomas Gleixner, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
This clock is managed since commit 705bc96c2c15313c ("irqchip:
renesas-intc-irqpin: Add minimal runtime PM support").
Also add an example while we're at.
