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.
