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.
