1OMAP Control Module bindings 2 3Control Module contains miscellaneous features under it based on SoC type. 4Pincontrol is one common feature, and it has a specialized support 5described in [1]. Typically some clock nodes are also under control module. 6Syscon is used to share register level access to drivers external to 7control module driver itself. 8 9See [2] for documentation about clock/clockdomain nodes. 10 11[1] Documentation/devicetree/bindings/pinctrl/pinctrl-single.txt 12[2] Documentation/devicetree/bindings/clock/ti/* 13 14Required properties: 15- compatible: Must be one of: 16 "ti,am3-scm" 17 "ti,am4-scm" 18 "ti,dm814-scrm" 19 "ti,dm816-scrm" 20 "ti,omap2-scm" 21 "ti,omap3-scm" 22 "ti,omap4-scm-core" 23 "ti,omap4-scm-padconf-core" 24- reg: Contains Control Module register address range 25 (base address and length) 26 27Optional properties: 28- clocks: clocks for this module 29- clockdomains: clockdomains for this module 30 31Examples: 32 33scm: scm@2000 { 34 compatible = "ti,omap3-scm", "simple-bus"; 35 reg = <0x2000 0x2000>; 36 #address-cells = <1>; 37 #size-cells = <1>; 38 ranges = <0 0x2000 0x2000>; 39 40 omap3_pmx_core: pinmux@30 { 41 compatible = "ti,omap3-padconf", 42 "pinctrl-single"; 43 reg = <0x30 0x230>; 44 #address-cells = <1>; 45 #size-cells = <0>; 46 #interrupt-cells = <1>; 47 interrupt-controller; 48 pinctrl-single,register-width = <16>; 49 pinctrl-single,function-mask = <0xff1f>; 50 }; 51 52 scm_conf: scm_conf@270 { 53 compatible = "syscon"; 54 reg = <0x270 0x330>; 55 #address-cells = <1>; 56 #size-cells = <1>; 57 58 scm_clocks: clocks { 59 #address-cells = <1>; 60 #size-cells = <0>; 61 }; 62 }; 63 64 scm_clockdomains: clockdomains { 65 }; 66} 67 68&scm_clocks { 69 mcbsp5_mux_fck: mcbsp5_mux_fck { 70 #clock-cells = <0>; 71 compatible = "ti,composite-mux-clock"; 72 clocks = <&core_96m_fck>, <&mcbsp_clks>; 73 ti,bit-shift = <4>; 74 reg = <0x02d8>; 75 }; 76}; 77
