| * usbnet: Fix tx_bytes statistic running backward in cdc_ncmBen Hutchings2015-03-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cdc_ncm disagrees with usbnet about how much framing overhead should be counted in the tx_bytes statistics, and tries 'fix' this by decrementing tx_bytes on the transmit path. But statistics must never be decremented except due to roll-over; this will thoroughly confuse user-space. Also, tx_bytes is only incremented by usbnet in the completion path. Fix this by requiring drivers that set FLAG_MULTI_FRAME to set a tx_bytes delta along with the tx_packets count.

| * usbnet: Fix tx_packets stat for FLAG_MULTI_FRAME driversBen Hutchings2015-03-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the usbnet core does not update the tx_packets statistic for drivers with FLAG_MULTI_PACKET and there is no hook in the TX completion path where they could do this. cdc_ncm and dependent drivers are bumping tx_packets stat on the transmit path while asix and sr9800 aren't updating it at all. Add a packet count in struct skb_data so these drivers can fill it in, initialise it to 1 for other drivers, and add the packet count to the tx_packets statistic on completion.

| * | usb: renesas_usbhs: add support for USB-DMACYoshihiro Shimoda2015-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Renesas SoCs have the USB-DMAC. It is able to terminate transfers when a short packet is received, even if less bytes than the transfer counter size have been received. Also, it is able to send a short packet even if the packet size is not multiples of 8bytes. Since the previous code has used the interruption of USBHS controller when receiving packets even if this driver has used a dmac, a lot of interruptions has happened. This patch will reduce such interruptions. This patch allows to use the USB-DMAC on R-Car H2 and M2.

| * | usb: gadget: composite: add req_match method to usb_functionAndrzej Pietrasiewicz2015-03-10
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Non-standard requests can encode the actual interface number in a non-standard way. For example composite_setup() assumes that it is w_index && 0xFF, but the printer function encodes the interface number in a context-dependet way (either w_index or w_index >> 8). This can lead to such requests being directed to wrong functions. This patch adds req_match() method to usb_function. Its purpose is to verify that a given request can be handled by a given function. If any function within a configuration provides the method and it returns true, then it is assumed that the right function is found. If a function uses req_match(), it should try as hard as possible to determine if the request is meant for it. If no functions in a configuration provide req_match or none of them returns true, then fall back to the usual approach.

* | USB: add flag for HCDs that can't receive wakeup requests (isp1760-hcd)Alan Stern2015-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the USB stack assumes that all host controller drivers are capable of receiving wakeup requests from downstream devices. However, this isn't true for the isp1760-hcd driver, which means that it isn't safe to do a runtime suspend of any device attached to a root-hub port if the device requires wakeup. This patch adds a "cant_recv_wakeups" flag to the usb_hcd structure and sets the flag in isp1760-hcd. The core is modified to prevent a direct child of the root hub from being put into runtime suspend with wakeup enabled if the flag is set.

* | USB: ehci-platform: Support ehci reset after resume quirkWu Liang feng2015-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Rockchip rk3288 EHCI controller doesn't properly detect the case when a device is removed during suspend. Specifically, when usb resume from suspend, the EHCI controller maintaining the USB state (FLAG_CF is 1, Current Connect Status is 1), but a USB device (like a USB camera on rk3288) may have been disconnected actually. Let's add a quirk to force ehci to go into the usb_root_hub_lost_power() path and reset after resume. This should generally reset the whole controller and all ports and initialize everything cleanly again, and bring the devices back up. As part of this, rename the "hibernation" paramter of ehci_resume() to force_reset since hibernation is simply another case where we can't trust the autodetected status and need to force a reset of devices.

* | usb: core: buffer: smallest buffer should start at ARCH_DMA_MINALIGNSebastian Andrzej Siewior2015-01-09
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the following error pops up during "testusb -a -t 10" | musb-hdrc musb-hdrc.1.auto: dma_pool_free buffer-128, f134e000/be842000 (bad dma) hcd_buffer_create() creates a few buffers, the smallest has 32 bytes of size. ARCH_KMALLOC_MINALIGN is set to 64 bytes. This combo results in hcd_buffer_alloc() returning memory which is 32 bytes aligned and it might by identified by buffer_offset() as another buffer. This means the buffer which is on a 32 byte boundary will not get freed, instead it tries to free another buffer with the error message. This patch fixes the issue by creating the smallest DMA buffer with the size of ARCH_KMALLOC_MINALIGN (or 32 in case ARCH_KMALLOC_MINALIGN is smaller). This might be 32, 64 or even 128 bytes. The next three pools will have the size 128, 512 and 2048. In case the smallest pool is 128 bytes then we have only three pools instead of four (and zero the first entry in the array). The last pool size is always 2048 bytes which is the assumed PAGE_SIZE / 2 of 4096. I doubt it makes sense to continue using PAGE_SIZE / 2 where we would end up with 8KiB buffer in case we have 16KiB pages. Instead I think it makes sense to have a common size(s) and extend them if there is need to. There is a BUILD_BUG_ON() now in case someone has a minalign of more than 128 bytes.

Users of this IP can now have a single driver built for host and device roles. DWC3 got support for two new HW platforms: Exynos7 and AMD. The Broadcom USB 3.0 Device Controller IP is now supported and so is PLX USB338x, which means DWC3 has lost is badge as the only USB 3.0 peripheral IP supported on Linux.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | USB gadgets composed with configfs lack suspend and resume methods. This patch uses composite_suspend()/composite_resume() the same way e.g. composite_setup() or composite_disconnect() are used in a configfs-based gadget.

| * | usb: Remove __init from early_dbgp_init() prototypeChris Rorvick2014-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Specifying these attributes in both the prototype and the function definition is unnecessary and could cause confusion or bugs if they are inconsistent. As such, __init should only be specified at the function definition.

| * | usb: Create separate header for ehci-dbgpChris Rorvick2014-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FUSBH200 and FOTG210 controllers implement sufficiently EHCI- compatible debug ports to leverage ehci-dbgp from their respective drivers. Rather than including <linux/usb/ehci_def.h> header, though, they replicate the necessary declarations in their own headers. Move the ehci-dbgp stuff into its own header as a first step towards removing this redundancy.

| * | usb: ehci: add ehci_port_power interfaceMichael Grzeschik2014-11-03
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current EHCI implementation is prepared to toggle the PORT_POWER bit to enable or disable a USB-Port. In some cases this port power can not be just toggled by the PORT_POWER bit, and the gpio-regulator is needed to be toggled too. This patch defines a port power control interface ehci_port_power for ehci core use, it toggles PORT_POWER bit as well as calls platform defined .port_power if it is defined.

|/ | | | | | | | | | | | | After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so quite a few depend on CONFIG_PM (or even dropped in some cases).

* USB: Add device quirk for ASUS T100 Base Station keyboardLu Baolu2014-09-24
| | | | | | | | | | | | | | | | | | This full-speed USB device generates spurious remote wakeup event as soon as USB_DEVICE_REMOTE_WAKEUP feature is set. As the result, Linux can't enter system suspend and S0ix power saving modes once this keyboard is used. This patch tries to introduce USB_QUIRK_IGNORE_REMOTE_WAKEUP quirk. With this quirk set, wakeup capability will be ignored during device configure. This patch could be back-ported to kernels as old as 2.6.39.
