X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=61fa8d694b8547894b57ea0d99d0120a58f6ebf8;p=deliverable%2Flinux.git usb: pl2303: also use the divisor based baud rate encoding method for baud rates < 115200 with HX chips Now that the divisor based baud rate encoding method has been fixed and extended, it can also be used for baud rates < 115200 baud with HX chips. This makes it possible to adjust the baud rate almost continuously instead of just beeing able to select between 16 fixed standard values. Tested with a PL2303HX 04463A (week 46, 2004, rev 3A).
