Subject: [PATCH v2 0/3] watchdog: Add Amlogic Meson GXBB Watchdog Timer driver

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.

Changes since v1 at http://lkml.kernel.org/r/1464614948-28247-1-git-send-email-narmstrong@baylibre.com :
- Update default timeout to 30sec
- Add separate CONFIG_
- Remove unused defines & functions
- Fix indentation
- Check set_timeout max value
- Reorder includes alphabetically
- Switch to human identify string
- clk_disable_unprepare on probe failure or removal

Changes since RFC version at http://lkml.kernel.org/r/1464249112-13658-1-git-send-email-narmstrong@baylibre.com :
- Remove status callback, will re-introduce it later to managed the already-running use case
- Fix registers defines indentation
- Fix space between operators
- Make all callbacks static functions
- Fix bindings with missing clocks attribute
- Do not stop/start watchdog on a timeout setup
- Fix probe device configuration
