Subject: V4L/DVB: cx23885: For CX23888 IR, configure the IO pin mux IR pins
explcitly
Author: Andy Walls
Date:Sun Jul 18 20:26:37 2010 -0300
Explicitly configure the IR Tx and IR Rx pins to be driven by the
IR Rx and Tx pads from the AV core for CX23888 IR.
For the HVR-1850 and HVR-1290 configure the IR Tx level inversion,
so the Tx LED is off when idle.
