Re: [PATCH v4 5/7] Watchdog: introduce ARM SBSA watchdog driver

[Fu Wei]

Hi Pratyush,

Great thanks for your help on some update for watchdog framework.

For " Fix parent of watchdog_devices", I will update my patchset.
For the upstreaming patchset"Sysfs status read support", will make a
patch. But upstream it when your patchset is merged.
