usb: gadget: fix request length error for isoc transfer

2017-01-12T10:39:19Z

commit 982555fc26f9d8bcdbd5f9db0378fe0682eb4188 upstream. For isoc endpoint descriptor, the wMaxPacketSize is not real max packet size (see Table 9-13. Standard Endpoint Descriptor, USB 2.0 specifcation), it may contain the number of packet, so the real max packet should be ep->desc->wMaxPacketSize && 0x7ff. Cc: Felipe F.

NET: usb: cdc_mbim: add quirk for supporting Telit LE922A

2016-12-08T18:02:25Z

Telit LE922A MBIM based composition does not work properly with altsetting toggle done in cdc_ncm_bind_common. This patch adds CDC_MBIM_FLAG_AVOID_ALTSETTING_TOGGLE quirk to avoid this procedure that, instead, is mandatory for other modems.

usb: gadget: add a new quirk to avoid skb_reserve in u_ether.c

2016-08-31T07:06:03Z

Some platforms (e.g. USB-DMAC on R-Car SoCs) has memory alignment restriction. If memory alignment is not match, the usb peripheral driver decides not to use the DMA controller. Then, the performance is not good. In the case of u_ether.c, since it calls skb_reserve() in rx_submit(), it is possible to cause memory alignment mismatch. So, this patch adds a new quirk "quirk_avoids_skb_reserve" to avoid skb_reserve() calling in u_ether.c to improve performance. A peripheral driver will set this flag and network gadget drivers (e.g. f_ncm.c) will reference the flag via gadget_avoids_skb_reserve(). Signed-off-by: Yoshihiro Shimoda Signed-off-by: Felipe Balbi

usb: gadget: composite: let USB functions process ctrl reqs in cfg0

2016-08-25T09:13:17Z

It can sometimes be necessary for gadget drivers to process non-standard control requests, which host devices can send without having sent USB_REQ_SET_CONFIGURATION. Therefore, the req_match() usb_function method is enhanced with the new parameter "config0". When a USB configuration is active, this parameter is false. When a non-core control request is processed in composite_setup(), without an active configuration, req_match() of the USB functions of all available configurations which implement this function, is called with config0=true. Then the control request gets processed by the first usb_function instance whose req_match() returns true. Signed-off-by: Felix Hädicke Signed-off-by: Felipe Balbi

usb: gadget: fix usb_ep_align_maybe endianness and new usb_ep_align

2016-08-25T09:13:13Z

USB spec specifies wMaxPacketSize to be little endian (as other properties), so when using this variable in the driver we should convert to the current CPU endianness if necessary. This patch also introduces usb_ep_align() which does always returns the aligned buffer size for an endpoint. This is useful to be used by USB requests allocator functions. Signed-off-by: Felipe F.

Merge tag 'usb-for-v4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next

2016-06-29T16:51:48Z

Felipe writes: usb: patches for v4.8 merge window Here's the big pull request for Peripheral stack and all related drivers. This time around with 109 non-merge commits mostly concentrated on drivers/usb/gadget/udc (41.5%) and drivers/usb/dwc3 (28.1%). There's a big rework on dwc3's transfer handling which gave us almost 3x faster USB3 speeds with Mass Storage on a particular test scenario I measured. We are also removing platform_data from dwc3 after converting all users to built-in properties instead. For the Gadget API, we're just adding tracepoints to aid debugging activities. Other than these, there's the usual set of spelling fixes, minor bug fixes and sparse warnings cleanups.

USB: EHCI: declare hostpc register as zero-length array

2016-06-25T00:03:12Z

The HOSTPC extension registers found in some EHCI implementations form a variable-length array, with one element for each port. Therefore the hostpc field in struct ehci_regs should be declared as a zero-length array, not a single-element array. This fixes a problem reported by UBSAN.

As a preparation for another cleanup, this moves the header file for the phy-msm-usb driver into the driver itself. No other file includes it any more, and we don't really want it in the global namespace anyway. Signed-off-by: Arnd Bergmann Signed-off-by: Felipe Balbi
