Subject: [PATCH v6 0/1] Bluetooth: mediatek: add gpio pin to reset bt

Reset Bluetooth using hardware pin via dts

Compared with the previously submitted version, the following
information are some specific revision histories

V5-->V6 modifications:
-Add specific revisions in the changes from v4 to v5.
-Add hardware pin title and descriptions to dt-binding submission
   information.
-Modify the title descriptions in the dt-binding file.
-Add 7925 what is it.
-Wrap the descriptions of MT7925 chip uses the USB bus appropriately.
-Change the compatible string to mediatek,mt7925-bluetooth in
   the dt-binding file and driver code.
-Drop gpio-controlelr properties in the dt-binding file.
-Modify the descriptions of the reset-gpios
   properties in the dt-binding file.
-Change the node information of reset-gpios in bluetooth
   from high level valid to low level valid.

V4-->V5 modifications:
-Correct the spelling error of word provides mentioned in V1.
-Drop the xhci0 node and status property in the dt-binding file.
-Modify the bt_reset tag node to bluetooth in the dt-binding file.
-Add #gpio-cell descriptions to properties, nodes and requests.
-Make a separate patch for the changes to dt-binding.

V3-->V4 modifications:
-Modify submission information why use hardware pin to reset Bluetooth.
-Write historical commit information into the cover letter.
-Modify dt binding format information and
   the explanation text in the dt-binding file.

V2-->V3 modifications:
-Changed the capitalization of co-developer names,
   using the correct capitalization of abbreviations and full
   name, and corrected obvious spelling errors.
-Add a revision history.
-Remove the "BT Driver" in the prefix.
-Add the bt-binding document, include inforamtion related to reset
   pin and compatibility matching.
-Add a comment before the schedule_delayed_work function call,
   although schedule_delayed_work is asynchronous, there is no risk.
   Even if it is not completed within 200ms, it will only postpone
   the subsequent probe and will not have any impact.
-Add a comment before the btmtk_reset_by_gpio function call,
   if the compatibility filed or pin cannot be found in the dts
   files, it can still reset bluetooth using software reset.

V2 modifications:
-Modify gpio to GPIO, SW to software,
   and fix other obvious spelling errors.
