If this property is not set and the device is put into Suspend-to-Idle mode, the watchdog triggers a reset after 128 seconds. Signed-off-by: Andrej Picej Reviewed-by: Fabio Estevam --- Changes in v4: - combine allOf, reorder allOf so it follows example-schema, drop the quotes around 'watchdog.yaml'. Changes in v3: - disallow the property for devices which don't support WDW bit functionality with .yaml DTS allOf:if:then scheme. Changes in v2: - add a commit message, - add a list of devices which support this functionality --- .../bindings/watchdog/fsl-imx-wdt.yaml | 37 +++++++++++++++++-- 1 file changed, 34 insertions(+), 3 deletions(-) diff --git a/Documentation/devicetree/bindings/watchdog/fsl-imx-wdt.yaml b/Documentation/devicetree/bindings/watchdog/fsl-imx-wdt.yaml index fb7695515be1..181f0cc5b5bd 100644 --- a/Documentation/devicetree/bindings/watchdog/fsl-imx-wdt.yaml +++ b/Documentation/devicetree/bindings/watchdog/fsl-imx-wdt.yaml @@ -9,9 +9,6 @@ title: Freescale i.MX Watchdog Timer (WDT) Controller maintainers: - Anson Huang -allOf: - - $ref: "watchdog.yaml#" - properties: compatible: oneOf: @@ -55,11 +52,45 @@ properties: If present, the watchdog device is configured to assert its external reset (WDOG_B) instead of issuing a software reset. + fsl,suspend-in-wait: + $ref: /schemas/types.yaml#/definitions/flag + description: | + If present, the watchdog device is suspended in WAIT mode + (Suspend-to-Idle).
