Hello,

here my new proposal for PXA27x USB device support. In this version I
fixed the power management support (suspend/resume).

As already mentioned in my previous, I know this driver is quite far
from perfection but, in my opinion, it could be a good starting point
to add this support into the kernel.

I use the driver from my platform specific file into
"arch/arm/mach-pxa/" by using the following code:

static int wwpc1100_udc_is_connected (void)
{
        return 1;
}

static void wwpc1100_udc_command (int cmd)
{
        switch (cmd) {
        case PXA2XX_UDC_CMD_DISCONNECT:
                pr_debug("%s: disconnect\n", __FUNCTION__);
                break;
        case PXA2XX_UDC_CMD_CONNECT:
                pr_debug("%s: connect\n", __FUNCTION__);
                break;
        default:
                printk(KERN_ERR "%s: unknown command!\n", __FUNCTION__);
                break;
        }
}

static struct pxa2xx_udc_mach_info wwpc1100_udc_mach_info = {
        .udc_is_connected       = wwpc1100_udc_is_connected,
        .udc_command            = wwpc1100_udc_command,
        .gpio_pullup            = WWPC1100_USBD_ENABLE,
};

Where WWPC1100_USBD_ENABLE is the GPIO number connected to a pull-up
on USB lines.

Please note that I'm using this driver under linux-2.6.20-rc6 but the
patch applies to linux-2.6.21-rc2!
