2011-05-10usb: gadget: composite: Allow function drivers to pause control transfersRoger Quadros1-1/+15
Some USB function drivers (e.g. f_mass_storage.c) need to delay or defer the data/status stages of standard control requests like SET_CONFIGURATION or SET_INTERFACE till they are done with their bookkeeping and are actually ready for accepting new commands to their interface. They can now achieve this functionality by returning USB_GADGET_DELAYED_STATUS in their setup handlers (e.g. set_alt()). The composite framework will then defer completion of the control transfer by not completing the data/status stages. This ensures that the host does not send new packets to the interface till the function driver is ready to take them. When the function driver that requested for USB_GADGET_DELAYED_STATUS is done with its bookkeeping, it should signal the composite framework to continue with the data/status stages of the control transfer. It can do so by invoking the new API usb_composite_setup_continue(). This is where the control transfer's data/status stages are completed and host can initiate new transfers. The DELAYED_STATUS mechanism is currently only supported if the expected data phase is 0 bytes (i.e. w_length == 0). Since SET_CONFIGURATION and SET_INTERFACE are the only cases that will use this mechanism, this is not a limitation.

USB hardware is put into low power mode when connected to a dedicated charging port. vbus_draw and set_power methods are implemented for determining the allowed current from Host in different states (un-configured/suspend/configured). The charger block is implemented using vendor specific registers and the PHY used in MSM8960(28nm PHY) different from older targets like MSM8x60 and MSM7x30(45nm PHY). The PHY vendor and product id registers are not implemented in the above chipsets. Hence PHY type is passed via platform data.

2011-05-03USB: EHCI: Support controllers with big endian capability regsJan Andersson1-2/+7
The two first HC capability registers (CAPLENGTH and HCIVERSION) are defined as one 8-bit and one 16-bit register. Most HC implementations have selected to treat these registers as part of a 32-bit register, giving the same layout for both big and small endian systems. This patch adds a new quirk, big_endian_capbase, to support controllers with big endian register interfaces that treat HCIVERSION and CAPLENGTH as individual registers.

2011-04-01usbnet: use eth%d name for known ethernet devicesArnd Bergmann1-0/+2
The documentation for the USB ethernet devices suggests that only some devices are supposed to use usb0 as the network interface name instead of eth0. The logic used there, and documented in Kconfig for CDC is that eth0 will be used when the mac address is a globally assigned one, but usb0 is used for the locally managed range that is typically used on point-to-point links. Unfortunately, this has caused a lot of pain on the smsc95xx device that is used on the popular pandaboard without an EEPROM to store the MAC address, which causes the driver to call random_ether_address(). Obviously, there should be a proper MAC addressed assigned to the device, and discussions are ongoing about how to solve this, but this patch at least makes sure that the default interface naming gets a little saner and matches what the user can expect based on the documentation, including for new devices. The approach taken here is to flag whether a device might be a point-to-point link with the new FLAG_POINTTOPOINT setting in the usbnet driver_info. A driver can set both FLAG_POINTTOPOINT and FLAG_ETHER if it is not sure (e.g. cdc_ether), or just one of the two. The usbnet framework only looks at the MAC address for device naming if both flags are set, otherwise it trusts the flag.

2011-03-30net/usb: Ethernet quirks for the LG-VL600 4G modemAndrzej Zaborowski1-0/+3
This adds a driver for the CDC Ethernet part of this modem. The device's ID is blacklisted in cdc_ether.c and is white-listed in this new driver because of the quirks needed to make it useful. The modem's firmware exposes a CDC ACM port for modem control and a CDC Ethernet port for network data. The descriptors look fine but both ports actually are some sort of multiplexers requiring non- standard headers added/removed from every packet or they get ignored. All information is based on a usb traffic log from a Windows machine. On the Verizon 4G network I've seen speeds up to 1.1MB/s so far with this driver, a speed-o-meter site reports 16.2Mbps/10.5Mbps.

2011-03-13USB: Remove bogus USB_PORT_STAT_SUPER_SPEED symbol.Sarah Sharp1-1/+0
USB_PORT_STAT_SUPER_SPEED is a made up symbol that the USB core used to track whether USB ports had a SuperSpeed device attached. This is a linux-internal symbol that was used when SuperSpeed and non-SuperSpeed devices would show up under the same xHCI roothub. This particular port status is never returned by external USB 3.0 hubs. (Instead they have a USB_PORT_STAT_SPEED_5GBPS that uses a completely different speed mask.) Now that the xHCI driver registers two roothubs, USB 3.0 devices will only show up under USB 3.0 hubs. Rip out USB_PORT_STAT_SUPER_SPEED and replace it with calls to hub_is_superspeed().

2011-03-13usb: Make core allocate resources per PCI-device.Sarah Sharp1-0/+7
Introduce the notion of a PCI device that may be associated with more than one USB host controller driver (struct usb_hcd). This patch is the start of the work to separate the xHCI host controller into two roothubs: a USB 3.0 roothub with SuperSpeed-only ports, and a USB 2.0 roothub with HS/FS/LS ports. One usb_hcd structure is designated to be the "primary HCD", and a pointer is added to the usb_hcd structure to keep track of that. A new function call, usb_hcd_is_primary_hcd() is added to check whether the USB hcd is marked as the primary HCD (or if it is not part of a roothub pair). To allow the USB core and xHCI driver to access either roothub in a pair, a "shared_hcd" pointer is added to the usb_hcd structure. Add a new function, usb_create_shared_hcd(), that does roothub allocation for paired roothubs. It will act just like usb_create_hcd() did if the primary_hcd pointer argument is NULL. If it is passed a non-NULL primary_hcd pointer, it sets usb_hcd->shared_hcd and usb_hcd->primary_hcd fields. It will also skip the bandwidth_mutex allocation, and set the secondary hcd's bandwidth_mutex pointer to the primary HCD's mutex. IRQs are only allocated once for the primary roothub. Introduce a new usb_hcd driver flag that indicates the host controller driver wants to create two roothubs. If the HCD_SHARED flag is set, then the USB core PCI probe methods will allocate a second roothub, and make sure that second roothub gets freed during rmmod and in initialization error paths. When usb_hc_died() is called with the primary HCD, make sure that any roothubs that share that host controller are also marked as being dead.

Later, when we have the xHCI driver register the two roothubs, we'll set the usb_hcd->bcdUSB field to HCD_USB2 for the USB 2.0 roothub, and HCD_USB3 for the USB 3.0 roothub.

2011-03-13USB 3.0 Hub ChangesJohn Youn1-4/+37
Update the USB core to deal with USB 3.0 hubs. These hubs have a slightly different hub descriptor than USB 2.0 hubs, with a fixed (rather than variable length) size. Change the USB core's hub descriptor to have a union for the last fields that differ. Change the host controller drivers that access those last fields (DeviceRemovable and PortPowerCtrlMask) to use the union. Translate the new version of the hub port status field into the old version that khubd understands. (Note: we need to fix it to translate the roothub's port status once we stop converting it to USB 2.0 hub status internally.) Add new code to handle link state change status. Send out new control messages that are needed for USB 3.0 hubs, like Set Hub Depth. This patch is a modified version of the original patch submitted by John Youn. It's updated to reflect the removal of the "bitmap" #define, and change the hub descriptor accesses of a couple new host controller drivers.

2011-03-07USB: move usbcore away from hcd->stateAlan Stern1-0/+4
The hcd->state variable is a disaster. It's not clearly owned by either usbcore or the host controller drivers, and they both change it from time to time, potentially stepping on each other's toes. It's not protected by any locks. And there's no mechanism to prevent it from going through an invalid transition. This patch (as1451) takes a first step toward fixing these problems. As it turns out, usbcore uses hcd->state for essentially only two things: checking whether the controller's root hub is running and checking whether the controller has died. Therefore the patch adds two new atomic bitflags to the hcd structure, to store these pieces of information. The new flags are used only by usbcore, and a private spinlock prevents invalid combinations (a dead controller's root hub cannot be running). The patch does not change the places where usbcore sets hcd->state, since HCDs may depend on them. Furthermore, there is one place in usb_hcd_irq() where usbcore still must use hcd->state: An HCD's interrupt handler can implicitly indicate that the controller died by setting hcd->state to HC_STATE_HALT. Nevertheless, the new code is a big improvement over the current code. The patch makes one other change. The hcd_bus_suspend() and hcd_bus_resume() routines now check first whether the host controller has died; if it has then they return immediately without calling the HCD's bus_suspend or bus_resume methods. This fixes the major problem reported in Bugzilla #29902: The system fails to suspend after a host controller dies during system resume.

2011-02-25USB: serial drivers need to use larger bulk-in buffersAlan Stern1-1/+2
When a driver doesn't know how much data a device is going to send, the buffer size should be at least as big as the endpoint's maxpacket value. The serial drivers don't follow this rule; many of them request only 256-byte bulk-in buffers. As a result, they suffer overflow errors if a high-speed device wants to send a lot of data, because high-speed bulk endpoints are required to have a maxpacket size of 512. This patch (as1450) fixes the problem by using the driver's bulk_in_size value as a minimum, always allocating buffers no smaller than the endpoint's maxpacket size.

2011-02-17tiocmget: kill off the passing of the struct fileAlan Cox1-1/+1
We don't actually need this and it causes problems for internal use of this functionality. Currently there is a single use of the FILE * pointer. That is the serial core which uses it to check tty_hung_up_p. However if that is true then IO_ERROR is also already set so the check may be removed.
