Bluetooth: mediatek: add support for MediaTek MT7663S and MT7668S SDIO devices (9aebfd4a) · Commits · 戴 / test

This adds the support of enabling MT7663S and MT7668S SDIO-based Bluetooth function. There are quite many differences between MT766[3,8]S and standard Bluetooth SDIO devices such as Type-A and Type-B devices. For example, MT766[3,8]S have its own SDIO registers layout, definition, SDIO packet format, and the specific flow should be programmed on them to complete the device initialization and low power control and so on. Currently, there are many independent programming sequences from the transport which are exactly the same as the ones in btusb.c about MediaTek support [1] and btmtkuart.c. We can try to split the transport independent Bluetooth setups on the advance, place them into the common files and allow varous transport drivers to reuse them in the future.
