2 * winbond-cir.c - Driver for the Consumer IR functionality of Winbond
3 * SuperI/O chips.
4 *
5 * Currently supports the Winbond WPCD376i chip (PNP id WEC1022), but
6 * could probably support others (Winbond WEC102X, NatSemi, etc)
7 * with minor modifications.
8 *
9 * Original Author: David Härdeman <david@hardeman.nu>
10 * Copyright (C) 2009 David Härdeman <david@hardeman.nu>
11 *
12 * Dedicated to Matilda, my newborn daughter, without whose loving attention
13 * this driver would have been finished in half the time and with a fraction
14 * of the bugs.
15 *
16 * Written using:
17 * o Winbond WPCD376I datasheet helpfully provided by Jesse Barnes at Intel
18 * o NatSemi PC87338/PC97338 datasheet (for the serial port stuff)
19 * o DSDT dumps
20 *
21 * Supported features:
22 * o RC6
23 * o Wake-On-CIR functionality
24 *
25 * To do:
26 * o Test NEC and RC5
27 *
28 * Left as an exercise for the reader:
29 * o Learning (I have neither the hardware, nor the need)
30 * o IR Transmit (ibid)
