SubjectRe: [PATCH v4 2/3] Bluetooth: hci_qca: Retry btsoc initialize when it fails
Hi Rocky,

> This patch adds the retry of btsoc initialization when it fails. There are
> reports that the btsoc initialization may fail on some platforms but the
> repro ratio is very low. The symptoms is the firmware downloading failed
> due to the UART write timed out. The failure may be caused by UART,
> platform HW or the btsoc itself but it's very difficlut to root cause,
> given the repro ratio is very low. Add a retry for the btsoc initialization
> can work around most of the failures and make Bluetooth finally works.
