From 75587f52c7b0d6c319515138a495a619b552a670 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 10 Oct 2011 22:01:51 -0700 Subject: usb: gadget: renesas_usbhs: add usbhs_bus_get_speed() 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.
