[PATCH 0/2] 8250: Allow 1% tolerance uartclk => max baud rate

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Greg,

Patch 1/2 is a patch redux originally sent in by James Hogan back in
Feb 2015. It allows for a marginally slower uart clk than nominal while
still supporting the max baud rate. This should not produce transmission
errors.

The discussion that followed the original submission is here:
http://www.spinics.net/lists/linux-serial/msg15916.html

James linked to a good background article on uart clk accuracy
http://www.maximintegrated.com/en/app-notes/index.mvp/id/2141

Patch 2/2 is a cleanup patch dependent on patch 1/2.

Regards,

Peter Hurley (2):
