From: Sean Wang <sean.wang@xxxxxxxxxxxx> This adds the support of enabling MT7668U and MT7663U UART based Bluetooth function running on the top of btmtkuart driver. We are through several patches to reach the goal and also wish applied the same flow in MediaTek btusb [1] for the transport independence. Once [1] and the series is being merged and then in next step I will consider to add a btmtk.c to hold these independent operations among various transport reused by MediaTek UART, USB and SDIO-based Bluetooth. Firstly, in patch 1/6 to update the dt-binding document for the kind of devices. in patch 2/6, 3/6 to fix the common error issues in the current code. in Patch 4/6, 5/6 to add the general flow which MT7622 and even MT7663U and MT7668U USB devices also utilize. Finally, in patch 6/6 to add the specific setups for MediaTek UART-based Bluetooth and enable MT7663U and MT7668U device.
