1Binding for TI DaVinci Power Sleep Controller (PSC)
2
3The PSC provides power management, clock gating and reset functionality. It is
4primarily used for clocking.
5
6Required properties:
7- compatible: shall be one of:
8	- "ti,da850-psc0" for PSC0 on DA850/OMAP-L138/AM18XX
9	- "ti,da850-psc1" for PSC1 on DA850/OMAP-L138/AM18XX
10- reg: physical base address and size of the controller's register area
11- #clock-cells: from common clock binding; shall be set to 1
12- #power-domain-cells: from generic power domain binding; shall be set to 1.
13- clocks: phandles to clocks corresponding to the clock-names property
14- clock-names: list of parent clock names - depends on compatible value
15	- for "ti,da850-psc0", shall be "pll0_sysclk1", "pll0_sysclk2",
16	  "pll0_sysclk4", "pll0_sysclk6", "async1"
17	- for "ti,da850-psc1", shall be "pll0_sysclk2", "pll0_sysclk4", "async3"
18
19Optional properties:
20- #reset-cells: from reset binding; shall be set to 1 - only applicable when
21  at least one local domain provides a local reset.
22
23Consumers:
24
25	Clock, power domain and reset consumers shall use the local power domain
26	module ID (LPSC) as the index corresponding to the clock cell. Refer to
27	the device-specific datasheet to find these numbers. NB: Most local
28	domains	only provide a clock/power domain and not a reset.
