Add base addresses for USBHOST, USBTLL, EHCI and OHCI to the header file. This will disappear when the drivers are converted to use the hwmod database, however this patch is needed until then. Signed-off-by: Anand Gadiyar <gadiyar@ti.com> Acked-by: Tony Lindgren <tony@atomide.com>

Update the ehci-omap glue layer to support the controller in the OMAP4. Major differences from OMAP3 is that the OMAP4 has per-port clocking, and supports ULPI output clocking mode. The old input clocking mode is not supported. Also, there are only 2 externally available ports as against 3 in the OMAP3. The third port is internally tied off and should not be used.

Use the recently updated aliases to get functional clocks needed by the driver. This allows the driver to acquire OMAP4-specific clocks without having to use different clock names for OMAP3 and OMAP4. Signed-off-by: Anand Gadiyar <gadiyar@ti.com>

Add clkdev aliases for the USBHOST and USBTLL clocks on OMAP3 and OMAP4, so that the driver can refer to the clocks using a common alias. This will disappear when the driver is converted to use the hwmod database, but until then this patch is needed.

Rename usbhost2_120m_fck to usbhost_hs_fck and usbhost1_48m_fck to usbhost_fs_fck, to better reflect the clocks' functionalities. In OMAP4, the frequencies for the corresponding clocks are not necessarily the same as with OMAP3, however the functionalities are.

Alan Stern authored
This patch (as1434) cleans up the uses of usb_mark_last_busy() in usbcore. The function will be called when a device is resumed and whenever a usage count is decremented. A call that was missing from the hub driver is added: A hub is used whenever one of its ports gets suspended (this prevents hubs from suspending immediately after their last child). In addition, the call to disable autosuspend support for new devices by default is moved from usb_detect_quirks() (where it doesn't really belong) into usb_new_device() along with all the other runtime-PM initializations. Finally, an extra pm_runtime_get_noresume() is added to prevent new devices from autosuspending while they are being registered.

This patch (as1428) converts USB over to the new runtime-PM core autosuspend framework. One slightly awkward aspect of the conversion is that USB devices will now have two suspend-delay attributes: the old power/autosuspend file and the new power/autosuspend_delay_ms file. One expresses the delay time in seconds and the other in milliseconds, but otherwise they do the same thing. The old attribute can be deprecated and then removed eventually.

Since the runtime-PM core already defines a .last_busy field in device.power, this patch uses it to replace the .last_busy field defined in usb_device and uses pm_runtime_mark_last_busy to implement usb_mark_last_busy.

Call pm_runtime_no_callbacks to set no_callbacks flag for USB interfaces. Since interfaces cannot be power-managed separately from their parent devices, there's no reason for the runtime-PM core to invoke any callbacks for them.

This patch adds the USB device driver of EG20T(Topcliff) PCH. EG20T PCH is the platform controller hub that is going to be used in Intel's upcoming general embedded platform. All IO peripherals in EG20T PCH are actually devices sitting on AMBA bus. EG20T PCH has USB device I/F. Using this I/F, it is able to access system devices connected to USB device.

This commit fixes some issues with File-backed Storage Gadget error recovery when registering LUN's devices. First of all, when device_register() fails the device still needs to be put. However, because lun_release() decreases fsg->ref reference counter the counter must be incremented beforehand. Second of all, after any of the device_create_file()s fails, device_unregister() is called which in turn (indirectly) calls lun_release() which decrements fsg->ref. So, again, the reference counter must be incremented beforehand. Lastly, if the first or the second device_create_file() succeeds, the files are never removed. To fix it, device_remove_file() needs to be called. This is done by simply marking LUN as registered prior to creating files so that fsg_unbind() can handle removing files.
