I check the schematic file. The GPIO4_21 pin is connected as following: - GPIO_1/VBUSDET -> PMIC_VBUS_DET -> VBUS_DET -> AM5728 GPIO4_21 pin Reviewed-by: Chanwoo Choi <cw00.c...@samsung.com> Thanks, Chanwoo Choi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
