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