Adds gpio interrupt handling support using an irqchip/irqdomain instantiation inside the GB GPIO driver. This implementation works on older kernels such as 3.10 that do not have the gpiolib irqchip helpers. Any line on a Greybus gpiochip may be configured as an interrupt. Once configured, IRQ event messages received from a module fire off the registered interrupt handler. Signed-off-by:

When initializing the USB device, we were starting up the svc message queue before the cport urbs were allocated. This might not be an issue for "slower" machines, but not having any allocated urbs for a cport might be an issue if we were to handle svc messages. So wait until everything is properly initialized and allocated before starting the svc urb. Signed-off-by: -

SVC messages come in in an "order", so don't mess them up by processing them out of order. Fix this by making our work queue ordered, which should keep everything in line. Reported-by:

Request type for all other protocols is defined like: GB_<protocol>_TYPE_<operation>, but for UART is like: GB_<protocol>_REQ_<operation>. Replace REQ with TYPE to make it consistent. It will also be useful in a later patch that creates get_version() routines with the help of a macro. Signed-off-by:

Some files are still prefixed with "gb-" with the reasoning that the modules would be named so, i.e. gb-*.ko. But this can be done by playing a bit in Makefile instead and keep uniform naming of .c files. Lets try it. Signed-off-by:

Some files are prefixed with "gb-" and some are suffixed with "-gb". The rationale behind the first one is that the modules would be named so, i.e. gb-*.ko. But there is no reason to keep the "-gb" suffix in the second case. Remove the unnecessary suffix. Signed-off-by:

If an operation is issued and the response never comes back, gb_operation_timeout() cancels the operation but never wakes up the waiter in gb_operation_request_send().
