This patchset contains changes to allow AUTOCTS to be set for the Synopsys DW UART driver. There is currently no way to set AUTOCTS unless the platform adds a quirk entry and sets the termios callback function. There was a discussion about a similar proposed patch change. It was mentioned in the discussion that the reason set_termios hook was not set by default is because someone might be using a certain type of clock that can't handle rate rounding and ended up using improper clock frequency for some baud rates. See discussion thread here. https://groups.google.com/forum/#!topic/fa.linux.kernel/oWrFOsw3rpQ The current dw8250_set_termios is set such that it always call the standard serial8250_do_set_termios. So if there are clock frequency issues, this will be resolved in serial8250_do_set_termios. This patchset has been tested on Cygnus VOIP board bcm911360_entphn board.
