imx6q pinmux

[angelo_d]

Hi, have some questions:

1) is setting of HYS and IBE bits enough to change pin direction into input ? From the pinmux port diagram, since the output

is connected to the input, any other bit needs to be set for the output part to be disabled ?

2) what happen to gpio output levels, when set to high, after cpu enters stop (deep-sleep) mode ? Levels are maintained ?

thanks

Thanks Igor,

have still a Linux related question in case,

pinctrl_hog: hoggrp {
            fsl,pins = <
                MX6QDL_PAD_SD3_RST__GPIO7_IO08        0x1b0b0

               >;
        };

If i understand correctly, this linux pinmux device setups cannot control direction, but only drive strength and other pad settings.

Is it correct ?

Thanks,

angelo

Hi Angelo

-  right, IBE bit enough to change pin direction into input 

-  levels are maintained in stop (deep-sleep) mode

Best regards
