7 title: Freescale i.MX General Power Controller v2
10 - Andrey Smirnov <andrew.smirnov@gmail.com>
13 The i.MX7S/D General Power Control (GPC) block contains Power Gating
14 Control (PGC) for various power domains.
16 Power domains contained within GPC node are generic power domain
17 providers, documented in
18 Documentation/devicetree/bindings/power/power-domain.yaml, which are
19 described as subnodes of the power gating controller 'pgc' node.
21 IP cores belonging to a power domain should contain a 'power-domains'
22 property that is a phandle for PGC node representing the domain.
39 interrupt-controller: true
45 description: list of power domains provided by this controller.

52 '#power-domain-cells':
57 Power domain index. Valid values are defined in
58 include/dt-bindings/power/imx7-power.h for fsl,imx7d-gpc and
59 include/dt-bindings/power/imx8m-power.h for fsl,imx8mq-gpc
60 include/dt-bindings/power/imx8mm-power.h for fsl,imx8mm-gpc
61 include/dt-bindings/power/imx8mp-power.h for fsl,imx8mp-gpc
66 A number of phandles to clocks that need to be enabled during domain
67 power-up sequencing to ensure reset propagation into devices located
68 inside this power domain.
76 A number of phandles to resets that need to be asserted during
77 power-up sequencing of the domain. The resets belong to devices
78 located inside the power domain, which need to be held in reset
79 across the power-up sequence. So no means to specify what each
80 reset is in a generic power-domain binding.
