| 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. |

| s2mps11_pmic@66 { |
| compatible = "samsung,s2mps11-pmic"; |
| reg = <0x66>; |
| |
| s2m_osc: clocks { |

| #clock-cells = <1>; |
| clock-output-names = "xx", "yy", "zz"; |
