BCM2835 PM (Power domains, watchdog)



The PM block controls power domains and some reset lines, and includes

a watchdog timer.  This binding supersedes the brcm,bcm2835-pm-wdt

binding which covered some of PM's register range and functionality.



Required properties:



- compatible:		Should be "brcm,bcm2835-pm"

- reg:			Specifies base physical address and size of the two

			  register ranges ("PM" and "ASYNC_BRIDGE" in that

			  order)

- clocks:		a) v3d: The V3D clock from CPRMAN

			b) peri_image: The PERI_IMAGE clock from CPRMAN

			c) h264: The H264 clock from CPRMAN

			d) isp: The ISP clock from CPRMAN

- #reset-cells: 	Should be 1.  This property follows the reset controller

			  bindings[1].

- #power-domain-cells:	Should be 1.  This property follows the power domain

			  bindings[2].



Optional properties:



- timeout-sec:		Contains the watchdog timeout in seconds

- system-power-controller: Whether the watchdog is controlling the

    system power.  This node follows the power controller bindings[3].

		 <&clocks BCM2835_CLOCK_ISP>;

	clock-names = "v3d", "peri_image", "h264", "isp";
