Subject: [RFC/PATCH v2 01/16] dt-bindings: soc: bcm: bcm2835-pm: Convert bindings to DT schema
Date: Tue, 9 Feb 2021 13:58:57 +0100 [thread overview]
Message-ID: <20210209125912.3398-2-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20210209125912.3398-1-nsaenzjulienne@suse.de>

-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].
