Subject: [RFC PATCH 0/3] watchdog: Add Amlogic Meson GXBB Watchdog Timer driver
Date: Thu, 26 May 2016 09:51:49 +0200 [thread overview]
Message-ID: <1464249112-13658-1-git-send-email-narmstrong@baylibre.com> (raw)
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.
