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>;
};
};
