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. > > Signed-off-by: Rocky Liao <rjliao@xxxxxxxxxxxxxx> > --- > > Changes in v2: None > Changes in v3: None > Changes in v4: > -rebased the patch with latet code > -refined macro and variable name > -updated commit message > > drivers/bluetooth/hci_qca.c | 19 +++++++++++++++++++ > 1 file changed, 19 insertions(+) patch has been applied to bluetooth-next tree.
