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.

You seem to be adding spaces instead of a tab here.
It is currently indented with spaces, I just added my condition there :)
But will spin a v2 with this suggested change, I'm all for consistency :)
Cheers, Quentin
