Brandon,

I have made changes to the cx18 driver code to add in the IR chip reset
support for the Z8F0811 IR microcontroller chip on the HVR-1600.  I have
done no testing aside from making sure that the change didn't break the
cx18 driver when not using IR.

You can find it as the latest change in this repository:

http://linuxtv.org/hg/~awalls/cx18-i2c/


I am also including my best guess at a patch to the lirc_pvr150.c module
for the HVR-1600.  I have not compiled it; I have not tested it.  It's
what I think needed to be done, which is not a lot given the HVR-1600's
similarity to the PVR-150.  Please let me know how testing turns out.

Regards,
Andy
