dt-bindings: net: bluetooth: Add MediaTek MT7921S SDIO Bluetooth

2024-05-14T14:51:07Z

The MediaTek MT7921S is a WiFi/Bluetooth combo chip that works over SDIO. WiFi and Bluetooth are separate SDIO functions within the chip. While the Bluetooth SDIO function is fully discoverable, the chip has a pin that can reset just the Bluetooth core, as opposed to the full chip. This should be described in the device tree. Add a device tree binding for the Bluetooth SDIO function of the MT7921S specifically to document the reset line. This binding is based on the MMC controller binding, which specifies one device node per SDIO function.

dt-bindings: bluetooth: add 'qcom,local-bd-address-broken'

2024-03-29T13:48:37Z

Several Qualcomm Bluetooth controllers lack persistent storage for the device address and instead one can be provided by the boot firmware using the 'local-bd-address' devicetree property. The Bluetooth bindings clearly states that the address should be specified in little-endian order, but due to a long-standing bug in the Qualcomm driver which reversed the address some boot firmware has been providing the address in big-endian order instead. The only device out there that should be affected by this is the WCN3991 used in some Chromebooks. Add a 'qcom,local-bd-address-broken' property which can be set on these platforms to indicate that the boot firmware is using the wrong byte order. Note that ChromeOS always updates the kernel and devicetree in lockstep so that there is no need to handle backwards compatibility with older devicetrees.

The servers for the @codeaurora domain are long retired and any messages sent there will bounce. Update the maintainer addresses for this binding to match the entries in .mailmap so that anyone looking in the file for a contact will see a correct address.
