Add Device Tree binding documentation for the clocks outputs in the Maxim 77802 Power Management IC. Signed-off-by: Javier Martinez Canillas <javier.martinez@collabora.co.uk> --- Changes since v4: None Changes since v3: - Don't use the same clock driver name in clock-names since it's a consumer concept and most probably will be different. Suggested by Doug Anderson. Changes since v2: - Split the DT binding documentation in a separate patch. .../devicetree/bindings/clock/maxim,max77802.txt | 42 ++++++++++++++++++++++ 1 file changed, 42 insertions(+) create mode 100644 Documentation/devicetree/bindings/clock/maxim,max77802.txt
