1 Freescale i.MX General Power Controller v2
2 ==========================================
4 The i.MX7S/D General Power Control (GPC) block contains Power Gating
5 Control (PGC) for various power domains.
9 - compatible: Should be "fsl,imx7d-gpc"
11 - reg: should be register base and length as documented in the
14 - interrupts: Should contain GPC interrupt request 1
16 Power domains contained within GPC node are generic power domain
17 providers, documented in
18 Documentation/devicetree/bindings/power/power_domain.txt, which are
19 described as subnodes of the power gating controller 'pgc' node,
20 which, in turn, is expected to contain the following:
24 - reg: Power domain index. Valid values are defined in
25 include/dt-bindings/power/imx7-power.h
27 - #power-domain-cells: Should be 0
31 - power-supply: Power supply used to power the domain
36 compatible = "fsl,imx7d-gpc";
37 reg = <0x303a0000 0x1000>;
39 interrupts = <GIC_SPI 87 IRQ_TYPE_LEVEL_HIGH>;
40 #interrupt-cells = <3>;
41 interrupt-parent = <&intc>;
47 pgc_pcie_phy: power-domain@1 {
48 #power-domain-cells = <0>;
51 power-supply = <®_1p0d>;
57 Specifying power domain for IP modules
58 ======================================
60 IP cores belonging to a power domain should contain a 'power-domains'
61 property that is a phandle for PGC node representing the domain.
63 Example of a device that is part of the PCIE_PHY power domain:
66 reg = <0x33800000 0x4000>,
69 power-domains = <&pgc_pcie_phy>;
