Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

*(tony.olech@elandigitalsystems.com)
|
|
*
|
|
* The driver was written by Tony Olech(tony.olech@elandigitalsystems.com)
|
|
* based on various USB client drivers in the 2.6.15 linux kernel
|
|
* with constant reference to the 3rd Edition of Linux Device Drivers
|
|
* published by O'Reilly
|
|
*
|
|
* The U132 adapter is a USB to CardBus adapter specifically designed
|
|
* for PC cards that contain an OHCI host controller. Typical PC cards
|
|
* are the Orange Mobile 3G Option GlobeTrotter Fusion card.
|
|
*
|
|
* The U132 adapter will *NOT *work with PC cards that do not contain
|
|
* an OHCI controller. A simple way to test whether a PC card has an
|
|
* OHCI controller as an interface is to insert the PC card directly
|
|
* into a laptop(or desktop) with a CardBus slot and if "lspci" shows
|
|
* a new USB controller and "lsusb -v" shows a new OHCI Host Controller
|
|
* then there is a good chance that the U132 adapter will support the
|
|
* PC card.(you also need the specific client driver for the PC card)
|
|
*
|
|
* Please inform the Author and Maintainer about any PC cards that
|
|
* contain OHCI Host Controller and work when directly connected to
|
|
* an embedded CardBus slot but do not work when they are connected
|
|
* via an ELAN U132 adapter.
|
|
*
|
|
* The driver consists of two modules, the "ftdi-u132" module is
|
|
* a USB client driver that interfaces to the FTDI chip within
|
|
* the U132 adapter manufactured by Elan Digital Systems, and the
|
|
* "u132-hcd" module is a USB host controller driver that talks
|
|
* to the OHCI controller within CardBus card that are inserted
|
|
* in the U132 adapter.
|
|
*
|
|
* The "ftdi-u132" module should be loaded automatically by the
|
|
* hot plug system when the U132 adapter is plugged in. The module
|
|
* initialises the adapter which mostly consists of synchronising
|
|
* the FTDI chip, before continuously polling the adapter to detect
|
|
* PC card insertions. As soon as a PC card containing a recognised
|
|
* OHCI controller is seen the "ftdi-u132" module explicitly requests
|
|
* the kernel to load the "u132-hcd" module.
|
|
*
|
|
* The "ftdi-u132" module provides the interface to the inserted
|
|
* PC card and the "u132-hcd" module uses the API to send and receive
|
|
* data. The API features call-backs, so that part of the "u132-hcd"
|
|
* module code will run in the context of one of the kernel threads
|
|
* of the "ftdi-u132" module.
