Javier mentioned it, please use EXYNOS_PIN_FUNC_OUTPUT

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,
Pankaj Dubey

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

Best regards,
