The patch updates mxs-auart driver to use new mctrl_gpio helpers for
gpio irqs. The code is much simpler now.

There is no changes since v1 (rebased only).

What is the problem here? For the other lines nothing needs to be done?
This comment doesn't match the coding style.
Right, the comment should be rather:
/* TODO: enable AUART_INTR_CTSMIEN
* if (!mctrl_gpio_is_gpio(atmel_port->gpios, UART_GPIO_CTS)) */
In this place I marked that CTSMIEN should be switched on
enable/disable_ms if CTS
is not a gpio. The driver enables CTSMIEN forever what is wrong but I
can't test it
and I don't need it so I've just marked the fact in the comment.
Other than that, this patch looks good.
Uwe
Thanks
Janusz
