* updated comments in code fo Deassert RTS patch
Balakrishna Godavarthi (3):
Bluetooth: hci_qca: use wait_until_sent() for power pulses
Bluetooth: hci_qca: Deassert RTS while baudrate change command
Bluetooth: hci_qca: Disable IBS state machine and flush Tx buffer
drivers/bluet
with newer baudrate, On host side
we are still operating in 115200 bps which results of reading garbage
data. Here we are pulling RTS line, so that chip we will wait to send data
to host until host change its baudrate.

Hi Balakrishna,
Latest qualcomm chips are not sending an command complete event for
every firmware packet sent to chip. They only respond with a vendor
specific event for the
time. Due to this we are seeing a timeout error
message logs on the console during firmware download. Now we are
injecting a command complete event once we receive an vendor
specific
event for the last RAM firmware packet.

During hci down we observed IBS sleep commands are queued in the Tx
buffer and hci_uart_write_work is sending data to the chip which is
not required as the chip is powered off. This patch will disable IBS
and flush the Tx buffer before we turn off the chip.
