Commit Message

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.

This should probably just be part of patch 1 to be clear you are moving 
things.

-* 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>;
-};
