Normally, the musb uses ep1 as the bidirectional bulk endpoint. This won't work on the Blackfin musb as all endpoints (except ep0) are unidirectional. Further, ep1-ep4 have a small 128 byte FIFO which makes them undesirable for bulk endpoints (which need more like a 512 byte FIFO). This leaves us with ep5-ep7 which have 1024 byte FIFOs and can be configured as either in/out and bulk/interrupt/iso on the fly. Signed-off-by:

I've got a crappy cypress converter here, and while running at higher baud rates craps out on throughput, it works fine with lower ones. While it'd be nice to simply use a lower baud rate, not all devices can be configured this way, and it is possible to (slowly) interact at higher rates by sending a byte at a time. So let people force higher rates when they need it via a module parameter. Signed-off-by:

The current code has a confusing duplicate new_baudrate init when setting the serial parameters. So just combine the if statement checks to avoid this. Signed-off-by:

Some devices which use mode switching revert to their primary mode as they are reset. They must not be reset for error handling. As user spaces makes the switch it also has to tell the kernel that a device is quirky. Signed-off-by:

Oliver Neukum authored
Some devices must be switched to a new mode to fully use them. A reset would make them revert to the old mode. Therefore a reset must not be used for error handling with such devices. Signed-off-by:

it's expected that the transceiver driver will initialize and call the notifier chain when necessary. Implement that for twl4030-usb driver. Signed-off-by:
-
Felipe Balbi authored
The notifier will be used to communicate usb events to other drivers like the charger chip. This can be used as source of information to kick usb charger detection as described by the USB Battery Charging Specification 1.1 and/or to pass bMaxPower field of selected usb_configuration to charger chip in order to use that information as input current on the charging profile setup.

An incorrect sizeof() resulted in only 4 (or 8) octets of the CHID being checked instead of all 16 octets. A randomly generated CHID had a probability of being unable to start a WUSB host of less than 1 in 2 billion. Signed-off-by:

EHCI FSL controller preserve its state during sleep mode, so nothing fancy needs to be done. Though, during 'deep sleep' mode (as found in MPC831x CPUs) the controller turns off and needs to be reinitialized upon resume. This patch adds support for hibernation and resuming after deep sleep. Based on Dave Liu and Jerry Huang's work[1]. [1] http://www.bitshrine.org/gpp/linux-fsl-2.6.24.3-MPC8315ERDB-usb-power-mangement.patchSigned-off-by:

This patch fix audio record functionality for some Full speed sound blaster devices. Issue: Sometimes transaction complete indication is coming from HW one frame later. Solution: If scan_periodic process now frame or previous frame now-1 and sitd transaction is not finished yet, exit scan_periodic function and check the same transaction in the next frame.

Add a new host controller driver method, reset_device(), that the USB core will use to notify the host of a successful device reset. The call may fail due to out-of-memory errors; attempt the port reset sequence again if that happens. Update hub_port_init() to allow resetting a configured device. Signed-off-by:

When a USB device is reset, the xHCI hardware must know, in order to match the device state and disable all endpoints except control endpoint 0. Issue a Reset Device command after a USB device is successfully reset. Wait on the command to finish, and then cache or free the disabled endpoint rings. There are four different USB device states that the xHCI hardware tracks: - disabled/enabled - device connection has just been detected, - default - the device has been reset and has an address of 0, - addressed - the device has a non-zero address but no configuration has been set, - configured - a set configuration succeeded. The USB core may issue a port reset when a device is in any state, but the Reset Device command will fail for a 0.96 xHC if the device is not in the addressed or configured state. Don't consider this failure as an error, but don't free any endpoint rings if this command fails. A storage driver may request that the USB device be reset during error handling, so use GPF_NOIO instead of GPF_KERNEL while allocating memory for the Reset Device command. Signed-off-by:

Add the hub emulation code to allow ports on an xHCI root hub to be disabled. Add the code to clear the port enabled/disabled bit, and clear the port enabled/disabled change bit. Like EHCI, the port cannot be enabled by setting the port enabled/disabled bit. Instead, a port is enabled by the host controller after a reset. Signed-off-by:

Sarah Sharp authored
Refactor the code to clear the port change bits in the port status register. All port status change bits are write one to clear. Remove a redundant port status read that was supposed to unblock any posted writes. We read the port after the write to get the updated status for debugging, so the port read after that is unnecessary. Signed-off-by:

All commands that can be issued to the xHCI hardware can come back with vendor-specific "informational" completion codes. These are to be treated like a successful completion code. Refactor out the code to test for the range of these codes and print debugging messages. Signed-off-by:

Sarah Sharp authored
The xhci_command structure is the basic structure for issuing commands to the xHCI hardware. It contains a struct completion (so that the issuing function can wait on the command), command status, and a input context that is used to pass information to the hardware. Not all commands need the input context, so make it optional to allocate. Allow xhci_free_container_ctx() to be passed a NULL input context, to make freeing the xhci_command structure simple.

Refactor out the code to cache or free endpoint rings from recently dropped or disabled endpoints. This code will be used by a new function to reset a device and disable all endpoints except control endpoint 0. Signed-off-by:

Sarah Sharp authored
If we fail to queue an evaluate context command or a configure endpoint command to the command ring in xhci_configure_endpoint(), we need to remove the xhci_command structure from the device's command list before returning. If the command is left on the command list, it will sit there indefinitely, blocking commands submitted after this fails. Signed-off-by:

This patch (as1316) adds some error checking to usb_submit_urb(). It's conditional on CONFIG_USB_DEBUG, so it won't affect normal users. The new check makes sure that the actual type of the endpoint described by urb->pipe agrees with the type encoded in the pipe value. The USB error code documentation is updated to include the code returned by the new check, and the usbfs SUBMITURB handler is updated to use the correct pipe type when legacy user code tries to submit a bulk transfer to an interrupt endpoint.
