Subject: [PATCH V2 4/4] dt-bindings: watchdog: remove i.MX system controller watchdog
Date: Sun, 28 Apr 2019 03:27:17 +0000 [thread overview]
Message-ID: <1556421727-7401-4-git-send-email-Anson.Huang@nxp.com> (raw)
In-Reply-To: <1556421727-7401-1-git-send-email-Anson.Huang@nxp.com>
i.MX system controller watchdog now depends on SCU driver, so it
needs to be subnode of SCU node in DT, binding doc is moved to
fsl,scu.txt as well.

-* Freescale i.MX System Controller Watchdog
-
-i.MX system controller watchdog is for i.MX SoCs with system controller inside,
-the watchdog is managed by system controller, users can ONLY communicate with
-system controller from secure mode for watchdog operations, so Linux i.MX system
-controller watchdog driver will call ARM SMC API and trap into ARM-Trusted-Firmware
-for watchdog operations, ARM-Trusted-Firmware is running at secure EL3 mode and
-it will request system controller to execute the watchdog operation passed from
-Linux kernel.
-
-Required properties:
-- compatible: Should be :
- "fsl,imx8qxp-sc-wdt"
- followed by "fsl,imx-sc-wdt";
-
-Optional properties:
-- timeout-sec : Contains the watchdog timeout in seconds.
-
-Examples:
-
-watchdog {
- compatible = "fsl,imx8qxp-sc-wdt", "fsl,imx-sc-wdt";
- timeout-sec = <60>;
-};
