1BCM2835 PM (Power domains, watchdog)
2
3The PM block controls power domains and some reset lines, and includes
4a watchdog timer.  This binding supersedes the brcm,bcm2835-pm-wdt
5binding which covered some of PM's register range and functionality.

7Required properties:
8
9- compatible:		Should be "brcm,bcm2835-pm"
10- reg:			Specifies base physical address and size of the two
11			  register ranges ("PM" and "ASYNC_BRIDGE" in that
12			  order)
13- clocks:		a) v3d: The V3D clock from CPRMAN
14			b) peri_image: The PERI_IMAGE clock from CPRMAN
15			c) h264: The H264 clock from CPRMAN
16			d) isp: The ISP clock from CPRMAN
17- #reset-cells: 	Should be 1.  This property follows the reset controller
18			  bindings[1].
19- #power-domain-cells:	Should be 1.  This property follows the power domain
20			  bindings[2].
21
22Optional properties:
23
24- timeout-sec:		Contains the watchdog timeout in seconds
25- system-power-controller: Whether the watchdog is controlling the
26    system power.  This node follows the power controller bindings[3].
