Add usb_remove_config to unbind a configuration and remove it from the configs list. This allows implementing composite gadget drivers that can disconnect themself from the bus and that will later be re-enumerated with a different configuration. Gadget drivers must call usb_gadget_disconnect before calling this function to disable the pullup, disconnect the device from the host, and prevent the host from enumerating the device while we are changing the gadget configuration.

As pointed out by Dan Carpenter, the check for NULL for the id variable is no longer needed, especially as we just dereferenced it a few lines earlier, causing an oops if it really was NULL. This was caused by 62bb84ed: "usb: gadget: ci13xxx: convert to platform device". Reported-by:

As pointed out by Dan Carpenter, we should not be trying to call dev_err() on a structure that was previously determined to be NULL, that's just foolish and asking for trouble. So just delete the message, it's not going to do anyone any good to have it anyway. This problem was caused by 0f089094: "usb: gadget: ci13xxx: replace home-brewed logging with dev_{err,warn,info}" Reported-by:

A possible race condition appears because we are not initializing the ohci->regs before calling usb_hcd_request_irqs(). We move the call to ohci_init() in hcd->driver->reset() instead of hcd->driver->start() to fix this. This was experienced when we share the same IRQ line between OHCI and EHCI controllers.

Currently, endpoints are initialized in gadget start/stop methods, however for the new style gadgets it is expected that bind() can be called before controller's start(), and we need endpoints already initialized at that point. So, move endpoint initialization to controller's probe before we switch to the "new style" gadget framework. Signed-off-by:

Logging output in the driver is mostly done using custom err/warn/info macros which rely on the existence of the global variable _udc, which is a global reference to the udc controller structure. This reference will have to go in order to allow us to have more than one chipidea udc in the system. Thus, replace custom macros with dev_{err,warn,info} using the platform device where possible. The trace() macro, which is a nop by default is left for tracing purposes. Signed-off-by:

Use lookup table instead of conditional macrodefinitions of register addresses. With two different possible register layouts and different register offsets, it's easiest to build a table with register addresses at probe time, based on the information supplied from the platform and device capabilities. This way we get rid of branch-per-register-access. Signed-off-by:

This reworks the usb_serial_register_drivers() and usb_serial_deregister_drivers() to not need a pointer to a struct usb_driver anymore. The usb_driver structure is now created dynamically and registered and unregistered as needed. This saves lines of code in each usb-serial driver. All in-kernel users of these functions were also fixed up at this time. The pl2303 driver was tested that everything worked properly. Thanks for the idea to do this from Alan Stern.

Currently, the register prefixes in the driver seem to be mixed: the capability registers are the ones that contain capability information, such as number of hardware endpoints, while the registers that are used to program the controller are called operational registers. Normally, capability registers start at 0x100 offset of the register window and are followed by operational registers. In some versions, however, capability registers start at 0x0 offset. This patch renames the register and adjusts their offsets appropriately, leaving the possibility of having a non-standard capability offset. I couldn't find any mentions of the TESTMODE register anywhere, so I suspect it might only be enabled in chipidea internal versions of the controller and I'm really inclined to remove it from the driver or at least hiding it behind a config option.

This patch (as1551) cleans up the PM-related entries in the usb_driver structures of the various USB serial driver modules. Those entries are now filled in by the usb-serial core during driver registration, so they don't need to be initialized explicitly in the source code. The same is true of the one remaining no_dynamic_id entry. reset_resume remains a small problem, because the serial core doesn't support it. The patch ignores these entries. Signed-off-by:

This patch (as1550) fixes a bug in the usb-serial core that affects the ftdi_sio driver and most likely others as well. The core implements suspend and resume routines, but it doesn't store pointers to those routines in the usb_driver structures that it registers, even though it does set those drivers' supports_autosuspend flag. The end result is that when one of these devices is autosuspended, we try to call through a NULL pointer. The patch fixes the problem by setting the suspend and resume method pointers to the appropriate routines in the USB serial core, along with the supports_autosuspend field, in each driver as it is registered. This should be back-ported to all the stable kernels that have the new usb_serial_register_drivers() interface. Signed-off-by:

usb: dwc3: patches for v3.5 merge window This pull request contains one workaround for a Silicon Issue found on all RTL releases prior to 2.20a, which would cause a metastability state on Run/Stop bit. We also have some patches implementing a few extra Standard requests introduced by USB3 spec (Set SEL and Set Isoch Delay), as well as one patch, which has been pending for a long time, implementing LPM support. Last, but not least, we are splitting the host address space out of the dwc3 core driver otherwise xHCI won't be able to request_mem_region() its own address space. This patch is only needed because we are (as we should) re-using the xHCI driver, which is a completely separate module. Together with these three big changes, come a few extra preparatory patches which most move code around, define macros and so on, as well as a fix for Isochronous transfers which hasn't been triggered before.

Merge tag 'gadget-for-v3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next usb: gadget: patches for v3.5 This pull request is quite big, but mainly because there's a giant rework of the s3c_hsotg.c driver to make it friendlier for other users. Samsung Exynos platforms use the DesignWare Core USB2 IP from Synopsys so it's a bit unfair to have the driver work for Samsung platforms only. In short, the big rework is in preparation to make the driver more reusable. Another big rework in this pull request came from Ido, where he's removing the redundant pointer for the endpoint descriptor from the controller driver's own endpoint representation. The same pointer is available through the generic struct usb_ep structure. Also on this pull request is the conversion of a few extra controller drivers to the new style registration, which allows multiple controllers to be available on the same platform and helps remove global pointers from those drivers. Together with those big changes, there's the usual fixes and cleanups to gadget drivers. Nothing major.
