The only drivers including serial_mctrl_gpio.h is atmel_serial.c,
clps711x.c, mxs-auart.c and etraxfs-uart.c

etraxfs commit
7b9c5162c182 ("serial: etraxfs-uart: use mctrl_gpio helpers for handling modem signals")
is heavily influenced by
62b0a1b3e759 ("serial: clps711x: Use mctrl_gpio helpers for handling modem signals")

a driver which also appears to lack mctrl irq setup/handling.


Uwe, are you going to convert all serial drivers that includes serial_mctrl_gpio.h to
use the new mctrl_gpio_init? (which also sets up irqs)

Since mctrl gpios are optional in the device tree, I guess mctrl_gpio_init handles if
they are missing. So even if etraxfs-uart.c currently lacks mctrl irq setup/handling,
if we migrate it to use the new mctrl_gpio_init, we will get this automatically?
