+Device Tree Bindings for Freescale i.MX8M Generic Power Domain
+==============================================================
+The binding for the i.MX8M Generic power Domain[1].
+
+[1] Documentation/devicetree/bindings/power/power_domain.txt
+
+Required properties:
+
+ - compatible: should be of:
+ - "fsl,imx8m-power-domain"
+ - #power-domain-cells: Number of cells in a PM domain Specifier, must be 0
+ - domain-index: should be the domain index number need to pass to TF-A
+ - domain-name: the name of this pm domain
+
+Optional properties:
+ - clocks: a number of phandles to clocks that need to be enabled during
+ domain power-up sequence to ensure reset propagation into devices
+ located inside this power domain
+ - power-supply: Power supply used to power the domain
+ - parent-domains: the phandle to the parent power domain
+
+example:
+ vpu_g1_pd: vpug1-pd {
+ compatible = "fsl,imx8mm-pm-domain";
+ #power-domain-cells = <0>;
+ domain-index = <6>;
+ domain-name = "vpu_g1";
+ parent-domains = <&vpumix_pd>;
+ clocks = <&clk IMX8MM_CLK_VPU_G1_ROOT>;
+ };
+
+
+Specifying Power domain for IP modules
+======================================
+
+IP cores belonging to a power domain should contain a 'power-domains'
+property that is a phandle for PGC node representing the domain.
+
+Example of a device that is part of the vpu_g1 power domain:
+ vpu_g1: vpu_g1@38300000 {
+ /* ... */
+ interrupts = <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>;
+ interrupt-names = "irq_hantro";
+ /* ... */
+ power-domains = <&vpu_g1_pd>;
+ };
