[v2,0/2] bluetooth: mt7921s: Add binding and fixup existing dts

Hi everyone,

This is v2 of my MT7921S Bluetooth binding series.

Changes since v1:
- Reworded descriptions in binding
- Moved binding maintainer section before binding description
- Added missing reference to bluetooth-controller.yaml
- Added missing GPIO header to example

This short series adds a binding document for the MT7921S SDIO Bluetooth
controller. The MT7921S is a SDIO-based WiFi/Bluetooth combo. WiFi and
Bluetooth are separate SDIO functions. The chip has extra per-subsystem
reset lines that can reset only WiFi or Bluetooth cores.

Patch 1 documents the SDIO function and the reset line, based on
existing device tree and driver usage. I listed Sean Wang, the original
driver author and maintainer, as the maintainer of the binding.

Patch 2 fixes up the sole existing usage of the compatible string by
making it a proper SDIO function node.

Please take a look. Not sure which tree patch 1 should be merged
through? I suppose with proper acks it could go through the soc/mediatek
tree together with patch 2.


Regards
ChenYu
