If the endpoint type is unknown, set it to 0 and fail gracefully instead of causing a kernel panic. Signed-off-by:

We may have more speed types in the future, so fail gracefully, rather than causing the kernel to panic. BUG() was called if the device speed was unknown when setting max packet size. Set the max packet size at the same time as the slot speed and get rid of one switch statement with BUG() option completely. [Note: Sarah merged a patch that she wrote that touched the xhci_setup_addressable_virt_dev function with this patch from Mathias for clarity.] Signed-off-by:

Fail gracefully, instead of causing the kernel to panic, if the input control context doesn't have the right type (XHCI_CTX_TYPE_INPUT). Push finding the pointer to the input control context up into functions that can fail. Signed-off-by: -

It's horrible coding style to panic the kernel when someone passes you an argument value you didn't expect. In the future, we may want to add additional context types, so it's better to gracefully handle additional context types instead of panicking. Signed-off-by:

Felipe writes: usb: patches for v3.11 merge window All function drivers are now converted to our new configfs-based binding. Eventually this will help us getting rid of in-kernel gadget drivers and only keep function drivers in the kernel. MUSB was taught that it needs to be built for host-only and device-only modes too. We had this support long ago but it involved a ridiculous amount of ifdefs. Now we have a much cleaner approach. Samsung Exynos4 platform now implements HSIC support. We're introducing support for AB8540 and AB9540 PHYs. MUSB module reinsertion now works as expected, before we were getting -EBUSY being returned by the resource checks done on driver core. DWC3 now has minimum support for TI's AM437x series of SoCs. OMAP5 USB3 PHY learned one extra DPLL configuration values because that PHY is reused in TI's DRA7xx devices. We're introducing support for Faraday fotg210 UDCs. Last, but not least, the usual set of non-critical fixes and cleanups ranging from usage of platform_{get,set}_drvdata to lock improvements.

This patch adds wrappers to dwc3_omap_readl/writel calls to accomodate both OMAP5 and AM437x reg maps (It uses the cached register offsets). Also renames OMAP5 IRQ1 as IRQMISC and IRQ1 bits as IRQMISC bits. Signed-off-by:

This patch Initializes the register offset values depending on the X_MAJOR of USBOTGSS_REVISION register. Also adds register offset defines and new debug register defines. X_MAJOR is 2 for both OMAP5 and AM437x. But both have different glue register layout. Differentiate AM437x using dt compatible. Register offsets are cached in dwc3_omap struct for reg reads and writes. Signed-off-by:

AM437x and OMAP5 dwc3 subsytem have different register map. Major differences are as follows. OMAP5 has one main interrupt and one misc interrupt Aegis has four main interrupts and one misc interrupt. Miscellanous Interrupt offsets are changed. UTMI OTG Control and Status Registers offsets are changed. DEBUG Configuration and Status Registers are changed. The main intend of the patch is to re-use the same wrapper driver for both OMAP5 and AM437x, by using the x_major in revision register and adjusting the offsets. This patch adds the register map offsets and adds offset variables in struct dwc3_omap to cache the offsets Signed-off-by:

If cfg->product name is not set, a default name is chosen depending on the common->luns->cdrom flag. If the flag is set the name should be "File-CD Gadget", and if the flag is not set the name should be "File-Stor Gadget". Acked-by:

The usb_serial_port structure had the number field, which was the minor number for the port, which almost no one really cared about. They really wanted the number of the port within the device, which you had to subtract from the minor of the parent usb_serial_device structure. To clean this up, provide the real minor number of the port, and the number of the port within the serial device separately, as these numbers might not be related in the future. Bonus is that this cleans up a lot of logic in the drivers, and saves lines overall. Tested-by:

Converting rndis to the new function interface requires converting the USB rndis' function code and its users. This patch converts the f_rndis.c to the new function interface. The file is now compiled into a separate usb_f_rndis.ko module. The old function interface is provided by means of a preprocessor conditional directives. After all users are converted, the old interface can be removed. Signed-off-by:
