Binding for Samsung S2M and S5M family clock generator block ============================================================ This is a part of device tree bindings for S2M and S5M family multi-function devices. More information can be found in bindings/mfd/sec-core.txt file. The S2MPS11/13/15 and S5M8767 provide three(AP/CP/BT) buffered 32.768 kHz outputs. The S2MPS14 provides two (AP/BT) buffered 32.768 KHz outputs. To register these as clocks with common clock framework instantiate under main device node a sub-node named "clocks". It uses the common clock binding documented in: - Documentation/devicetree/bindings/clock/clock-bindings.txt Required properties of the "clocks" sub-node: - #clock-cells: should be 1. - compatible: Should be one of: "samsung,s2mps11-clk", "samsung,s2mps13-clk", "samsung,s2mps14-clk", "samsung,s5m8767-clk" The S2MPS15 uses the same compatible as S2MPS13, as both provides similar clocks. Each clock is assigned an identifier and client nodes use this identifier to specify the clock which they consume.
