-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].
