Unfortunately, I still can't get these to work on my system.

Per your "Re: atmel_mxt_ts: defaulting irqflags to
IRQF_TRIGGER_FALLING", I set up the IRQ type in the Tegra DT file, and
then applied this series on top of next-20140721. The driver appears to
initialize OK, but neither X nor evtest see any events from the device.
The IRQ count in /proc/interrupts doesn't increase when I touch the
touchpad, but does when I press it hard enough to trigger the physical
button. A boot log with debug enabled follows. No additional kernel log
messages are generated by touches or clicks. Do you have any idea what I
should try?
