watchdog: Clean up defaults for imx_watchdog / ulp_wdog

2023-01-20T17:27:23Z

In imx_watchdog, clean up the comment to just note the range now, as we do not need to set the default here as Kconfig does this for us. For ulp_wdog, set the default value via Kconfig instead. Cc: Stefan Roese Cc: Stefano Babic Cc: Peng Fan Signed-off-by: Tom Rini Reviewed-by: Stefan Roese

watchdog: Drop GD_FLG_WDT_READY as it's not used any more

2022-11-22T07:56:26Z

Since commit c2fd0ca1a822 ("watchdog: Integrate watchdog triggering into the cyclic framework") GD_FLG_WDT_READY has become write-only. This patch now removes this flag completely. The vacant spot in gd_flags is filled with the newly introduced GD_FLG_CYCLIC_RUNNING flag. Suggested-by: Rasmus Villemoes Signed-off-by: Stefan Roese

watchdog: designware: make reset really optional

2022-11-22T07:56:26Z

Checking for DM_RESET is not enough since not all watchdog implementations use a reset lane. Such is the case for Rockchip implementation for example. Since reset_assert_bulk will only succeed if the resets property exists in the watchdog DT node, it needs to be called only if a reset property is present. This adds a condition on the resets property presence in the watchdog DT node before assuming a reset lane needs to be fetched with reset_assert_bulk, by calling ofnode_read_prop.

watchdog: ulp_wdog: add driver model for ulp watchdog driver

2022-10-24T09:10:21Z

Enable driver model for ulp watchdog timer. When CONFIG_WDT=y and the status of device node is "okay", initr_watchdog will be called and finally calls ulp_wdt_probe() and ulp_wdt_start(). Signed-off-by: Alice Guo Reviewed-by: Ye Li Reviewed-by: Stefan Roese

watchdog: ulp_wdog: enable watchdog interrupt on imx93

2022-10-24T09:10:21Z

The reset source of the external PMIC on i.MX93 is WDOG_ANY PAD and the source of WDOG_ANY PAD is interrupt. Therefore, using PMIC to reset needs to enable the watchdog interrupt. Signed-off-by: Alice Guo Reviewed-by: Stefan Roese
