Subject: Re: [PATCH v3 0/3] watchdog: Add Amlogic Meson GXBB Watchdog Timer driver

Hi Neil,

> Adds support for the Amlogic Meson GXBB SoC Watchdog Timer.
> It differs from the meson6/meson8b HW, so need for a separate driver.
> The HW provides a divider capable of having a 1ms timebase thus simplifying
> the counter update.
> The restart call is not provided even if the HW is capable of triggering a
> system reset immediately because of the PSCI firmare having such functionnality.
> The watchdog is not expected to be running at boot time since there is a separate
> system-level watchdog running from the SCPI co-processor, but this case would be
> handle in a next driver update.
