[PATCH 3/8] clk: bcm2835: add missing osc and per clocks

From: kernel at martin.sperl.org <hidden>
Date: 2016-02-29 15:43:57
Also in: linux-clk, linux-devicetree
Subsystem: common clk framework, open firmware and flattened device tree bindings, the rest · Maintainers: Michael Turquette, Stephen Boyd, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

From: Martin Sperl <redacted>

Add definitions for the following clocks:
* AVE0
* DFT
* GP0
* GP1
* GP2
* PULSE
* SLIM
* SMI
* TEC
