I've got the CX23888 integrated IR Rx done and Tx nearly done. I was waiting to see how kfifo and lirc_dev panned out before making the interface to userspace. The CX23885, CX23418, and CX2584x integrated IR is essentially the same. I hope to have CX23885 IR done by Christmas. Both of those IR devices are/will be encapsulated in a v4l2_subdevice object internally. I was going to write lirc_v4l glue between the v4l2_device/v4l2_subdev_ir_ops and lirc_dev. As for the the I2C chips, I was going to go back and encapsulate those in the v4l2_subdevice object as well, so then my notional lirc_v4l could pick those up too. The I2C subsystem only allows one binding to an I2C client address/name on a bus. So without some new glue like a notional lirc_v4l, it *may* be hard to share between ir-kbd-i2c and lirc_i2c and lirc_zilog.
