+ *  winbond-cir.c - Driver for the Consumer IR functionality of Winbond

+ *
+ *  Currently supports the Winbond WPCD376i chip (PNP id WEC1022), but

+ *  with minor modifications.

+ *  Original Author: 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:
