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
yes correct

Hi Angelo
- right, IBE bit enough to change pin direction into input
- levels are maintained in stop (deep-sleep) mode
Best regards
