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 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
