Subject: [PATCH v3 0/3] Allwinner R329 and D1 watchdog support

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.

Samuel Holland (3):
  dt-bindings: watchdog: sunxi: Add compatibles for R329
  dt-bindings: watchdog: sunxi: Add compatibles for D1
  watchdog: sunxi_wdt: Add support for D1
