USB: ftdi-elan: client driver for ELAN Uxxx adapters
This "ftdi-elan" module is one half of the "driver" for ELAN's Uxxx series adapters which are USB to PCMCIA CardBus adapters. Currently only the U132 adapter is available and it's module is called "u132-hcd". When the USB hot plug subsystem detects a Uxxx series adapter it should load this module. Upon a successful device probe() the jtag device file interface is created and the status workqueue started up. The jtag device file interface exists for the purpose of updating the firmware in the Uxxx series adapter, but as yet it had never been used. The status workqueue initializes the Uxxx and then sits there polling the Uxxx until a supported PCMCIA CardBus device is detected it will start the command and respond workqueues and then load the module that handles the device. This will initially be only the u132-hcd module. The status workqueue then just polls the Uxxx looking for card ejects. The command and respond workqueues implement a command sequencer for communicating with the firmware on the other side of the FTDI chip in the Uxxx. This "ftdi-elan" module exports some functions to interface with the sequencer. Note that this module is a USB client driver. Note that the "u132-hcd" module is a (cut-down OHCI) host controller. Thus we have a topology with the parent of a host controller being a USB client! This really stresses the USB subsystem semaphore/mutex handling in the module removal.
