Javier mentioned it, please use EXYNOS_PIN_FUNC_OUTPUT

EXYNOS_PIN_PULL_NONE

> +		samsung,pin-drv = <0>;

I think these are the same as in Exynos5422, so EXYNOS5420_PIN_DRV_LV1

Best regards,
Krzysztof

Yes, but as it's not taken care in existing dts for other pin
definitions, so a Javier mentioned, this can be taken care as a separate
patch for all pin definitions? Or do you want me to first add patch
converting all these with macros and then on top of add this usb related
pin definitions.

Thanks,

For new code let's use the macros even if entire file is not converted
(yet). The same like mixture of values and GPIO_ACTIVE_* macros. If
you wish to convert the file to macros, feel free to go. But I see it
as separate patch.
