Bluetooth: hci_qca: wait for Pre shutdown complete event before sending the Power off pulse (010376ab) · Commits · 戴 / test

When SoC receives pre shut down command, it share the same with other COEX shared clients. So SoC needs a short time after sending VS pre shutdown command before turning off the regulators and sending the power off pulse. Along with short delay, needs to wait for command complete event for Pre shutdown VS command Signed-off-by:
