| OMAP PRCM bindings |
| |
| Power Reset and Clock Manager lists the device clocks and clockdomains under |
| a DT hierarchy. Each TI SoC can have multiple PRCM entities listed for it, |
| each describing one module and the clock hierarchy under it. see [1] for |
| documentation about the individual clock/clockdomain nodes. |

| Required properties: |
| - compatible: Must be one of: |
| "ti,am3-prcm" |
| "ti,am4-prcm" |
| "ti,omap2-prcm" |
| "ti,omap3-prm" |
| "ti,omap3-cm" |
| "ti,omap4-cm1" |
| "ti,omap4-prm" |
| "ti,omap4-cm2" |
| "ti,omap4-scrm" |
| "ti,omap5-prm" |
| "ti,omap5-cm-core-aon" |
| "ti,omap5-scrm" |
| "ti,omap5-cm-core" |
| "ti,dra7-prm" |
| "ti,dra7-cm-core-aon" |
| "ti,dra7-cm-core" |
| "ti,dm814-prcm" |
| "ti,dm816-prcm" |
| - reg: Contains PRCM module register address range |
| (base address and length) |
| - clocks: clocks for this module |
| - clockdomains: clockdomains for this module |
| |
| Example: |
| |
| cm: cm@48004000 { |
| compatible = "ti,omap3-cm"; |
| reg = <0x48004000 0x4000>; |
| |
| cm_clocks: clocks { |
| #address-cells = <1>; |
| #size-cells = <0>; |
| }; |
| |
| cm_clockdomains: clockdomains { |
| }; |
| } |
| |
| &cm_clocks { |
| omap2_32k_fck: omap_32k_fck { |
| #clock-cells = <0>; |
| compatible = "fixed-clock"; |
| clock-frequency = <32768>; |
| }; |
| }; |
| |
| &cm_clockdomains { |
| core_l3_clkdm: core_l3_clkdm { |
| compatible = "ti,clockdomain"; |
| clocks = <&sdrc_ick>; |
| }; |
| }; |
