[PATCH v3 2/8] clk: sunxi: update clock-output-names dt binding documentation
From: Chen-Yu Tsai <hidden>
Date: 2014-01-09 08:52:39
Subsystem:
common clk framework, open firmware and flattened device tree bindings, the rest · Maintainers:

clock-output-names is now required for most of sunxi clock nodes, to provide the name of the corresponding clock. Add the new requirements, exceptions, as well as examples.
