1OMAP Control Module bindings2 3Control Module contains miscellaneous features under it based on SoC type.4Pincontrol is one common feature, and it has a specialized support5described in [1]. Typically some clock nodes are also under control module.6Syscon is used to share register level access to drivers external to7control module driver itself.8 9See [2] for documentation about clock/clockdomain nodes.10 11[1] Documentation/devicetree/bindings/pinctrl/pinctrl-single.yaml12[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 range31 (base address and length)32 33Optional properties:34- clocks: clocks for this module35- clockdomains: clockdomains for this module36 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};83
