-* Samsung Exynos Power Domains
-
-Exynos processors include support for multiple power domains which are used
-to gate power to one or more peripherals on the processor.
-
-Required Properties:
-- compatible: should be one of the following.
- * samsung,exynos4210-pd - for exynos4210 type power domain.
-- reg: physical base address of the controller and length of memory mapped
- region.
-- #power-domain-cells: number of cells in power domain specifier;
- must be 0.
-
-Optional Properties:
-- clocks: List of clock handles. The parent clocks of the input clocks to the
- devices in this power domain are set to oscclk before power gating
- and restored back after powering on a domain. This is required for
- all domains which are powered on and off and not required for unused
- domains.
-- clock-names: The following clocks can be specified:
- - oscclk: Oscillator clock.
- - clkN: Input clocks to the devices in this power domain. These clocks
- will be reparented to oscclk before swithing power domain off.
- Their original parent will be brought back after turning on
- the domain. Maximum of 4 clocks (N = 0 to 3) are supported.
- - asbN: Clocks required by asynchronous bridges (ASB) present in
- the power domain. These clock should be enabled during power
- domain on/off operations.
-- power-domains: phandle pointing to the parent power domain, for more details
- see Documentation/devicetree/bindings/power/power_domain.txt
-
-Node of a device using power domains must have a power-domains property
-defined with a phandle to respective power domain.
-
-Example:
-
- lcd0: power-domain-lcd0 {
- compatible = "samsung,exynos4210-pd";
- reg = <0x10023C00 0x10>;
- #power-domain-cells = <0>;
- };
-
- mfc_pd: power-domain@10044060 {
- compatible = "samsung,exynos4210-pd";
- reg = <0x10044060 0x20>;
- clocks = <&clock CLK_FIN_PLL>, <&clock CLK_MOUT_SW_ACLK333>,
- <&clock CLK_MOUT_USER_ACLK333>;
- clock-names = "oscclk", "pclk0", "clk0";
- #power-domain-cells = <0>;
- };

-See Documentation/devicetree/bindings/power/power_domain.txt for description
-of consumer-side bindings.
