Subject: Re: [PATCH 0/6]Bluetooth: mediatek: add support for MediaTek MT7663U
 and MT7668U UART devices

Hi Sean,

> in Patch 4/6, 5/6 to add the general flow which MT7622 and even MT7663U and

> Finally, in patch 6/6 to add the specific setups for MediaTek UART-based
> Bluetooth and enable MT7663U and MT7668U device.
