drivers:misc: ti-st: firmware download optimization
To fasten the process of firmware download, the chip allows disabling of the command complete event generation from host. In these cases, only few very essential commands would have the command complete events and hence the wait associated with them. So now the driver would wait for a command complete event, only when it comes across a wait event during firmware parsing. This would also mean we need to skip not just the change baud rate command but also the wait for it. Signed-off-by: Pavan Savoy <pavan_savoy@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
