From: Christine Zhu <hidden>

Supports MT8195 watchdog device.
Supports MT8195 watchdog reset-controller feature.

Change since v1:
  -Remove the unneeded tag in [v1,1/3] [v1,2/3] [v1,3/3]
  -Add of_device_id of MT8195 in [v1,3/3]
  -use more proper prefixes, such as "dt-bindings: mediatek: mt8195:"
  -provide more information in the cover letter

See [1] as a reference, "dt-bindings" is preferred.

  watchdog: mediatek: mt8195: add wdt support
If the commit messages in the 3 patches are sentences, they should end
with a period (i.e. ".").
