This will avoid Rx buffer descriptors overflow if more packets were received at one shot before we process the received ones.

| * usb: ci_udc: fix request allocation when endpoints are disabledRob Herring2015-07-241-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ci_udc driver request allocation assumes that the endpoint descriptor pointer is set to retrieve the endpoint number, but that is only true when the endpoint is enabled. This results in a NULL ptr dereference which for me happens to return 0 value. This causes the EP0 request struct to be returned for other endpoints. Some gadget drivers like fastboot and USB MS work fine, but ethernet does not. Really, the ci_udc driver is the oddball here doing this EP0 special case handling Stephen added. All the other drivers alloc/free functions are pretty much the same with the only variation being the size of the private struct. This could all be consolidated to a common function.

| * usb: CONFIG_USB_FASTBOOT prefix replacement for consistencyPaul Kocialkowski2015-07-221-4/+4
| | | | | | | | | | | | | | | | | | | | FASTBOOT is defined both by CONFIG_USB_FUNCTION_FASTBOOT AND CONFIG_CMD_FASTBOOT, so it doesn't make much sense to have a CONFIG_USB_FASTBOOT prefix for fastboot-specific options, especially given that other config options for fastboot use the CONFIG_FASTBOOT prefix. This replaces the CONFIG_USB_FASTBOOT prefix with CONFIG_FASTBOOT, for consistency. Signed-off-by: Paul Kocialkowski <contact@paulk.fr>

| * usb: gadget: fastboot: Dequeue the previous IN request for the current requestPaul Kocialkowski2015-07-221-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent versions of the fastboot tool will query the partition type before doing an operation on a partition (such as erase, flash, etc). It will then submit the operation as soon as the response for the partition type is received. Usually, the MUSB controller will see that the partition type request return status was read by the host at the very same time as the actual operation request is submitted by the host. However, the operation will be read first (int_rx is handled first in musb_interrupt) and after it is completed, the fastboot USB gadget driver will send another return status. Hence, this happens before the musb gadget framework has had a chance to handle the previous acknowledgement that the host read the return status and dequeue the request. The host will then usually empty the FIFO by the time musb_interrupt gets around handling the return status acknowledgement (for the previous request, this is still on the same musb_interrupt call), so no other interrupt is generated and the most recent return status acknowledgement remains unaccounted for. It will then be used as a response for the next command, and the proper response for it will be delayed to the next command, and so on. Dequeuing the previous IN request in the fastboot code ensures that no previous return status remains. It is acceptable to do it since there is no callback to it anyways.

| | | | | | | | | | | | | | | | | | This avoids handling requests that have an error status or no data. In particular, this avoids showing unnecessary error messages when the USB gadget gets disconnected (e.g. with fastboot continue) and the fastboot USB gadget driver sends an error back to the host (that has disconnected already).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some devices can take a long time to work out whether they have a new packet or now. For example the ASIX USB Ethernet dongle can take 5 seconds to do this, since it waits until it gets a new packet on the wire before allowing the USB bulk read packet to be submitted. At present with driver mode the Ethernet receive code reads 32 packets. This can take a very long time if we must wait for all 32 packets. The old code (before driver model) worked by reading a single set of packets from the USB device, then processing all the packets with in. It would be nice to use the same behaviour with driver model. Add a flag to the receive method which indicates that the driver should try to find a packet if available, by consulting the hardware. When the flag is not set, it should just return any packet data it has already received. If there is none, it should return -EAGAIN so that the loop will terminate.
