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.

  dt-bindings: watchdog: sunxi: Add compatibles for R329
  dt-bindings: watchdog: sunxi: Add compatibles for D1
  watchdog: sunxi_wdt: Add support for D1
