As far as I understand, since em485 callbacks are invoked by timers,
the code is to be executed in atomic context. However certain GPIO
controllers (particularly the OMAP-based one which is used on our
AM335x) require the use of the gpio_*_cansleep() functions, and cannot
work with the atomic-friendly non-cansleep ones. Do the aforementioned
helpers in serial_mctrl_gpio.c address this issue?
