Dear Janaki,
Thank you for your patch. Please be more specific in the summary/title:
Increase settling time for baudrate change VSC to 30 ms
Am 17.06.24 um 09:00 schrieb Janaki Ramaiah Thota:
This change is done to align the settling time and
synchronization for baudrate VSC for WCN6750.
In logging disabled builds and few devices
baudrate change and flow control is taking time
so increasing the wait time to controller and uart
to handle baudrate change request properly.
Is the 30 ms documented in some datasheet?
Please use 75 characters per line.
Please document the test system.
