1*4882a593SmuzhiyunBinding for Samsung S2M and S5M family clock generator block 2*4882a593Smuzhiyun============================================================ 3*4882a593Smuzhiyun 4*4882a593SmuzhiyunThis is a part of device tree bindings for S2M and S5M family multi-function 5*4882a593Smuzhiyundevices. 6*4882a593SmuzhiyunMore information can be found in bindings/mfd/sec-core.txt file. 7*4882a593Smuzhiyun 8*4882a593SmuzhiyunThe S2MPS11/13/15 and S5M8767 provide three(AP/CP/BT) buffered 32.768 kHz 9*4882a593Smuzhiyunoutputs. The S2MPS14 provides two (AP/BT) buffered 32.768 KHz outputs. 10*4882a593Smuzhiyun 11*4882a593SmuzhiyunTo register these as clocks with common clock framework instantiate under 12*4882a593Smuzhiyunmain device node a sub-node named "clocks". 13*4882a593Smuzhiyun 14*4882a593SmuzhiyunIt uses the common clock binding documented in: 15*4882a593Smuzhiyun - Documentation/devicetree/bindings/clock/clock-bindings.txt 16*4882a593Smuzhiyun 17*4882a593Smuzhiyun 18*4882a593SmuzhiyunRequired properties of the "clocks" sub-node: 19*4882a593Smuzhiyun - #clock-cells: should be 1. 20*4882a593Smuzhiyun - compatible: Should be one of: "samsung,s2mps11-clk", "samsung,s2mps13-clk", 21*4882a593Smuzhiyun "samsung,s2mps14-clk", "samsung,s5m8767-clk" 22*4882a593Smuzhiyun The S2MPS15 uses the same compatible as S2MPS13, as both provides similar 23*4882a593Smuzhiyun clocks. 24*4882a593Smuzhiyun 25*4882a593Smuzhiyun 26*4882a593SmuzhiyunEach clock is assigned an identifier and client nodes use this identifier 27*4882a593Smuzhiyunto specify the clock which they consume. 28*4882a593Smuzhiyun Clock ID Devices 29*4882a593Smuzhiyun ---------------------------------------------------------- 30*4882a593Smuzhiyun 32KhzAP 0 S2MPS11/13/14/15, S5M8767 31*4882a593Smuzhiyun 32KhzCP 1 S2MPS11/13/15, S5M8767 32*4882a593Smuzhiyun 32KhzBT 2 S2MPS11/13/14/15, S5M8767 33*4882a593Smuzhiyun 34*4882a593SmuzhiyunInclude dt-bindings/clock/samsung,s2mps11.h file to use preprocessor defines 35*4882a593Smuzhiyunin device tree sources. 36*4882a593Smuzhiyun 37*4882a593Smuzhiyun 38*4882a593SmuzhiyunExample: 39*4882a593Smuzhiyun 40*4882a593Smuzhiyun s2mps11_pmic@66 { 41*4882a593Smuzhiyun compatible = "samsung,s2mps11-pmic"; 42*4882a593Smuzhiyun reg = <0x66>; 43*4882a593Smuzhiyun 44*4882a593Smuzhiyun s2m_osc: clocks { 45*4882a593Smuzhiyun compatible = "samsung,s2mps11-clk"; 46*4882a593Smuzhiyun #clock-cells = <1>; 47*4882a593Smuzhiyun clock-output-names = "xx", "yy", "zz"; 48*4882a593Smuzhiyun }; 49*4882a593Smuzhiyun }; 50
