[PATCH v2 00/10] serial: st-asc: Allow handling of RTS line

[lee.jones@linaro.org (Lee Jones)]

Hi Greg, Jiri,

> When hardware flow-control is disabled, manual toggling of the UART's
> reset line (RTS) using userland applications (e.g. stty) is not
> possible, since the ASC IP does not provide this functionality in the
> same was as some other IPs do.  Thus, we have to do this manually.
> 
> This set ensures the correct Pinctrl groups are configured and
> obtained for both manual toggling of the RTS line and for the IP to
> take over the lines when HW flow-control is requested by the user.

Looks like everyone is happy with the set.

Are you planning to merge it?
