| * 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>; |
| }; |
