Subject: Re: [PATCH v2 00/10] Add MT7921 SDIO Bluetooth support

Hi Sean,

> The patchset adds the MT7921 SDIO (MT7921S) Blutooth support to btmtksdio
> driver, which basically are made up of 3 parts.
> 
> PART 1: patch 1-3 to create btmtk module to rely on
> 
> These are preliminary patches for MT7921s driver to move the common
> firmware download procedure and the common functions from MT7921u to btmtk
> module to make MT7921u, MT7921s and other devices can share with to reduce
> the unnecessary duplicated code being created.
> 
> PART 2: patch 4-8 to refactor btmtksdio prior to adding mt7921s
> 
> These are preliminary patches for MT7921s driver to refactor the current
> btmtksdio to make MT7921S is able to coexist with the devices the current
> driver can support with the generic code and improve the performance on
> packet transmitting and receving process.
> 
> PART 3: patch 9-10 to add specific mt7921s logic
> 
> Add the specific logic regarding to mt7921s bluetooth.
> 
> The changelog from v1 to v2:
> - fix the test failure reported from bluez test bot
> - fix the test warning reported from kernel test robot
> - rebase onto the up-to-date bluetooth-next/master 
> - fix the typo from mt7961_data to mt7921_data
> - improve the function btsdio_mtk_reg_read with dropping the hard coding
