2011-10-13usb: gadget: renesas_usbhs: bugfix: don't modify platform dataKuninori Morimoto
renesas_usbhs has default callback functions and settings. And it tried overwrite to platform private data if platform doesn't have them. So, if renesas_usbhs was compiled as module, it will be hung-up on 2nd insmod. This patch fixup it.

2011-10-13usb: gadget: renesas_usbhs: add usbhs_bus_get_speed()Kuninori Morimoto
current mod_gadget had got usb speed on usbhsg_irq_dev_state() which is status change interrupt callback function. And the usb speed data was included in its parameter. But this style works for mod_gadget, but doesn't work for mod_host which isn't interrupted when device status was changed. This patch add usbhs_bus_get_speed() to solve this issue.

2011-04-29usb: renesas_usbhs: add autonomy modeKuninori Morimoto
Current renesas_usbhs was designed to save power when USB is not connected. And it assumed platform uses callback to notify connection/disconnection by external interrupt. But some SuperH / platform board doesn't have such feature. This patch adds autonomy mode which detect USB connection/disconnection by internal interrupt. But power will be always ON when autonomy mode is selected. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
