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