Subject: RE: [PATCH v4 2/4] Bluetooth: hci_qca: Add support for QTI Bluetooth
 chip wcn6855

Hi Luiz and all:
  I am QC bt host guys,  today I sync up with qc btfw team and conclude following result:
1: as I mentioned before, qca2066 and wcn6855 are the same chip family, and they can share the same btfw patch, and distinguish by using different nvm based on board id.
2: I upload the btfw previously for qca2066 , you can refer to https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=2ba1beaae0c649ce8a50baecc8df9e81cd524e65 , and also wcn6855 can share to use btfw patch and nvm with qca2066.

3:steev patch does not include read board id part logical , I think it is better combine the steev  patch and my patch into one.

Regards.
Tim

Could you please review Steev changes, also if you could please refactor the code regarding the soc_type, making the necessary field as part of the data structure should make it a lot easier to add support for new configurations without having to change the code in multiple places.
