Subject: [PATCH v3 0/3] Allwinner R329 and D1 watchdog support
Date: Thu, 2 Sep 2021 17:57:47 -0500 [thread overview]
Message-ID: <20210902225750.29313-1-samuel@sholland.org> (raw)
This series adds bindings and driver support for the R329 and D1
watchdogs. The R329 is fully backward-compatible, so no driver changes
are needed for it.
v3 of this series adds two new compatibles, as I discovered that the
immediate "soft reset" functionality was specific to the watchdog that
is part of the same block as the sun4i timer, and is not available in
the RISC-V or DSP watchdog instances.
My intention is to use the soft reset function as OpenSBI's system reset
backend, so it needs to know which watchdog instance has that feature.
