[PATCH] serial: mxs-auart: use mctrl_gpio helpers for handling modem signals

2014-09-12 Thread Janusz Uzycki
Dedicated CTS and RTS pins are unusable together with a lot of other peripherals because they share the same line. Pinctrl is limited. Moreover, the USART controller doesn't handle DTR/DSR/DCD/RI signals, so we have to control them via GPIO. This patch permits to use GPIOs to control the
