* USB ATI Remote support
*
* Version 2.2.0 Copyright (c) 2004 Torrey Hoffman <thoffman@arnor.net>
* Version 2.1.1 Copyright (c) 2002 Vladimir Dergachev
*
* This 2.2.0 version is a rewrite / cleanup of the 2.1.1 driver, including
* porting to the 2.6 kernel interfaces, along with other modification
* to better match the style of the existing usb/input drivers. However, the
* protocol and hardware handling is essentially unchanged from 2.1.1.
*
* The 2.1.1 driver was derived from the usbati_remote and usbkbd drivers by
* Vojtech Pavlik.
*
* Changes:
*
* Feb 2004: Torrey Hoffman <thoffman@arnor.net>
* Version 2.2.0
* Jun 2004: Torrey Hoffman <thoffman@arnor.net>
* Version 2.2.1
* Added key repeat support contributed by:
* Vincent Vanackere <vanackere@lif.univ-mrs.fr>
* Added support for the "Lola" remote contributed by:
* Seth Cohn <sethcohn@yahoo.com>

*
* Hardware & software notes
*
* These remote controls are distributed by ATI as part of their
* "All-In-Wonder" video card packages. The receiver self-identifies as a
* "USB Receiver" with manufacturer "X10 Wireless Technology Inc".
*
* The "Lola" remote is available from X10. See:
* http://www.x10.com/products/lola_sg1.htm
* The Lola is similar to the ATI remote but has no mouse support, and slightly
* different keys.
*
* It is possible to use multiple receivers and remotes on multiple computers
* simultaneously by configuring them to use specific channels.
*
* The RF protocol used by the remote supports 16 distinct channels, 1 to 16.
* Actually, it may even support more, at least in some revisions of the
* hardware.
*
* Each remote can be configured to transmit on one channel as follows:
* - Press and hold the "hand icon" button.
* - When the red LED starts to blink, let go of the "hand icon" button.
* - When it stops blinking, input the channel code as two digits, from 01
* to 16, and press the hand icon again.
*
* The timing can be a little tricky. Try loading the module with debug=1
* to have the kernel print out messages about the remote control number
* and mask. Note: debugging prints remote numbers as zero-based hexadecimal.
*
* The driver has a "channel_mask" parameter. This bitmask specifies which
* channels will be ignored by the module. To mask out channels, just add
* all the 2^channel_number values together.
*
* For instance, set channel_mask = 2^4 = 16 (binary 10000) to make ati_remote
* ignore signals coming from remote controls transmitting on channel 4, but
* accept all other channels.
*
* Or, set channel_mask = 65533, (0xFFFD), and all channels except 1 will be
* ignored.
*
* The default is 0 (respond to all channels). Bit 0 and bits 17-32 of this
* parameter are unused.

/*
* A driver for the Griffin Technology, Inc. "PowerMate" USB controller dial.
*
* v1.1, (c)2002 William R Sowerbutts <will@sowerbutts.com>
*
* This device is a anodised aluminium knob which connects over USB. It can measure
* clockwise and anticlockwise rotation. The dial also acts as a pushbutton with
* a spring for automatic release. The base contains a pair of LEDs which illuminate
* the translucent base. It rotates without limit and reports its relative rotation
* back to the host when polled by the USB controller.
*
* Testing with the knob I have has shown that it measures approximately 94 "clicks"
* for one full rotation. Testing with my High Speed Rotation Actuator (ok, it was
* a variable speed cordless electric drill) has shown that the device can measure
* speeds of up to 7 clicks either clockwise or anticlockwise between pollings from
* the host. If it counts more than 7 clicks before it is polled, it will wrap back
* to zero and start counting again. This was at quite high speed, however, almost
* certainly faster than the human hand could turn it. Griffin say that it loses a
* pulse or two on a direction change; the granularity is so fine that I never
* noticed this in practice.
*
* The device's microcontroller can be programmed to set the LED to either a constant
* intensity, or to a rhythmic pulsing. Several patterns and speeds are available.
*
* Griffin were very happy to provide documentation and free hardware for development.
*
* Some userspace tools are available on the web: http://sowerbutts.com/powermate/
