[PATCH] gpio: mxs: implement get_direction callback

Hello again,

Also note that the atmel_get_lines_status function can be simplified to
just:

	status = UART_GET_CSR(port);
	return mctrl_gpio_get(atmel_port->gpios, &status);

thinking again, this is wrong because it uses the Atmel specific
register bits for the different flags, but with the generic solution
outlined in the previous mail this function wouldn't need to handle the
gpio parts at all.

Best regards
Uwe
