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