2015-11-19usb: sandbox: Add a USB emulation driverSimon Glass
Add a simple USB keyboard driver for sandbox. It provides a function to 'load' it with input data, which it will then stream through to the normal U-Boot input subsystem. When the input data is exhausted, the keyboard stops providing data. Signed-off-by: Simon Glass <sjg@chromium.org>

Allow USB device emulation to support interrupt URBs so that we can use USB keyboards with sandbox. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-11-19dm: usb: Remove inactive children after a bus scanSimon Glass
Each scan of the USB bus may return different results. Existing driver-model devices are reused when found, but if a device no longer exists it will stay around, de-activated, but bound. Detect these devices and remove them after the scan completes. Signed-off-by: Simon Glass <sjg@chromium.org>

2015-11-12fastboot: Implement NAND backendMaxime Ripard
So far the fastboot code was only supporting MMC-backed devices for its flashing operations (flash and erase). Add a storage backend for NAND-backed devices. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
2015-11-12fastboot: Implement flashing session counterMaxime Ripard
The fastboot flash command that writes an image to a partition works in several steps: 1 - Retrieve the maximum size the device can download through the "max-download-size" variable 2 - Retrieve the partition type through the "partition-type:%s" variable, that indicates whether or not the partition needs to be erased (even though the fastboot client has minimal support for that) 3a - If the image is smaller than what the device can handle, send the image and flash it. 3b - If the image is larger than what the device can handle, create a sparse image, and split it in several chunks that would fit. Send the chunk, flash it, repeat until we have no more data to send. However, in the 3b case, the subsequent transfers have no particular identifiers, the protocol just assumes that you would resume the writes where you left it. While doing so works well, it also means that flashing two subsequent images on the same partition (for example because the user made a mistake) would not work withouth flashing another partition or rebooting the board, which is not really intuitive. Since we have always the same pattern, we can however maintain a counter that will be reset every time the client will retrieve max-download-size, and incremented after each buffer will be flashed, that will allow us to tell whether we should simply resume the flashing where we were, or start back at the beginning of the partition.

2015-10-29smsc95xx: Use zero length packets when RX fifo is emptyStefan Brüns
Using NAKs on empty RX fifo for bulk in transfers is the right choice for a interrupt driven model, but U-Boot uses polling and expects an immediate answer if there is no incoming packet. Using ZLP Bulk In Response (BIR) mode avoids unexpected timeouts in the host controller driver. As ZLP mode is reset default, there is no need to set it.

Lowering the burst cap to the URB size ensures no packet spans multiple urbs. Caveat, lower limit for working burst cap is 5/33 HS/FS packets.

2015-09-12usb: ci_udc: fix emissions of ZLPsStephen Warren
Commit 6a132416359e "ci_udc: Update the ci_udc driver to support bulk transfers" caused the value of "len" to change without updating subsquent users of that variable in ci_ep_submit_next_request(). This caused the code that detects when to emit ZLPs (Zero Length Packets) never to trigger, which in turn caused host timeouts when a ZLP was required, which in turn broke tests/dfu/, even despite the assertion in that commit's description that "These changes are tested for both the DFU and lthor." Fix this by modifying the added dtd iteration code not to modify "len", but rather to keep state in a separate variable. Rename the variables while we're at it so they describe their purpose better.

2015-09-11usb: gadget: don't leak configs when unbindingStephen Warren
By the time g_dnl_unbind() is run, cdev->config has been set to NULL, so the free() there does nothing, and the config struct is leaked. Equally, struct usb_gadget contains a linked list of config structs, so the code should iterate over them all and free each one, rather than freeing one particular config struct. composite_unbind() already iterates over the list of config structs, and unlinks each from the linked list. Fix this loop to free() each struct as it's unlinked and otherwise forgotten.

Looking at the surrounding code, I found the same problem in all other composite gadget drivers in both the bind and unbind functions, as well as the udc platform driver 'remove' functions. Those will break if anyone uses the 'unbind' sysfs attribute to detach a device from a built-in driver. This patch removes the incorrect annotations from all the gadget drivers.

2015-09-07usb: ehci: remember init modeStephen Warren
When an EHCI device is registered in device mode, the HW isn't actually initialized at all, and hence isn't left in a running state. Consequently, when the device is deregistered, ehci_shutdown() will fail, since the HW bits it expects to see set in response to its shutdown requests will not be sent, and the message "EHCI failed to shut down host controller." will be printed. Fix ehci-hcd.c to remember whether the device was registered in host or device mode, and only call ehci_shutdown() for host mode registrations. Signed-off-by: Stephen Warren <swarren@nvidia.com>
