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 "ti,omap4-scm-wkup" 25 "ti,omap4-scm-padconf-wkup" 26 "ti,omap5-scm-core" 27 "ti,omap5-scm-padconf-core" 28 "ti,omap5-scm-wkup-pad-conf" 29 "ti,dra7-scm-core" 30- reg: Contains Control Module register address range 31 (base address and length) 32 33Optional properties: 34- clocks: clocks for this module 35- clockdomains: clockdomains for this module 36 37Examples: 38 39scm: scm@2000 { 40 compatible = "ti,omap3-scm", "simple-bus"; 41 reg = <0x2000 0x2000>; 42 #address-cells = <1>; 43 #size-cells = <1>; 44 ranges = <0 0x2000 0x2000>; 45 46 omap3_pmx_core: pinmux@30 { 47 compatible = "ti,omap3-padconf", 48 "pinctrl-single"; 49 reg = <0x30 0x230>; 50 #address-cells = <1>; 51 #size-cells = <0>; 52 #interrupt-cells = <1>; 53 interrupt-controller; 54 pinctrl-single,register-width = <16>; 55 pinctrl-single,function-mask = <0xff1f>; 56 }; 57 58 scm_conf: scm_conf@270 { 59 compatible = "syscon"; 60 reg = <0x270 0x330>; 61 #address-cells = <1>; 62 #size-cells = <1>; 63 64 scm_clocks: clocks { 65 #address-cells = <1>; 66 #size-cells = <0>; 67 }; 68 }; 69 70 scm_clockdomains: clockdomains { 71 }; 72} 73 74&scm_clocks { 75 mcbsp5_mux_fck: mcbsp5_mux_fck { 76 #clock-cells = <0>; 77 compatible = "ti,composite-mux-clock"; 78 clocks = <&core_96m_fck>, <&mcbsp_clks>; 79 ti,bit-shift = <4>; 80 reg = <0x02d8>; 81 }; 82};
