+ * renesas_usbhs driver can use external interrupt mode
+ * (which come from USB-PHY) or autonomy mode (it use own interrupt)
+ * for detecting connection/disconnection when Function.
+ * USB will be power OFF while it has been disconnecting
+ * if external interrupt mode, and it is always power ON if autonomy mode,
+ *
+ * mackerel can not use external interrupt (IRQ7-PORT167) mode on "USB0",
+ * because Touchscreen is using IRQ7-PORT40.
+ * It is impossible to use IRQ7 demux on this board.
+ *
+ * We can use external interrupt mode USB-Function on "USB1".
+ * USB1 can become Host by r8a66597, and become Function by renesas_usbhs.
+ * But don't select both drivers in same time.
+ * These uses same IRQ number for request_irq(), and aren't supporting
+ * IRQF_SHARD / IORESOURCE_IRQ_SHAREABLE.
+ *
+ * Actually these are old/new version of USB driver.
+ * This mean its register will be broken if it supports SHARD IRQ,
