ARM: shmobile: mackerel: fixup usb module order
renesas_usbhs driver can play role as both Host and Gadget. In case of Gadget, it requires not only renesas_usbhs but also usb gadget module (like g_ether). So, renesas_usbhs driver calls usb_add_gadget_udc() on probe time. Because of this behavior, Host port plays also Gadget role if kernel has both Host/Gadget support. In mackerel case, from 0ada2da51800a4914887a9bcf22d563be80e50be (ARM: mach-shmobile: mackerel: use renesas_usbhs instead of r8a66597_hcd) usb0 plays Gadget role, and usb1 plays Host role, and current mackerel board probes as usb1 -> usb0. Thus, 1st installed usb gadget module (like g_ether) will be assigned to usb1 (= usb Host port), and 2nd module to usb0 (= usb Gadget port). It is very confusable for user. This patch fixup usb modes probing order as usb0 -> usb1. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Simon Horman <horms@verge.net.au>
