2 * USB ATI Remote support
4 * Copyright (c) 2011, 2012 Anssi Hannula <anssi.hannula@iki.fi>
5 * Version 2.2.0 Copyright (c) 2004 Torrey Hoffman <thoffman@arnor.net>
6 * Version 2.1.1 Copyright (c) 2002 Vladimir Dergachev
8 * This 2.2.0 version is a rewrite / cleanup of the 2.1.1 driver, including
9 * porting to the 2.6 kernel interfaces, along with other modification
10 * to better match the style of the existing usb/input drivers. However, the
11 * protocol and hardware handling is essentially unchanged from 2.1.1.
13 * The 2.1.1 driver was derived from the usbati_remote and usbkbd drivers by
18 * Feb 2004: Torrey Hoffman <thoffman@arnor.net>
20 * Jun 2004: Torrey Hoffman <thoffman@arnor.net>
22 * Added key repeat support contributed by:
23 * Vincent Vanackere <vanackere@lif.univ-mrs.fr>
24 * Added support for the "Lola" remote contributed by:

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