 I am curious too, so i examined SMSC datasheet. The IRQ is fully programmable on
chip's side too, and our driver indeed defaults to active-low. You can switch it
to active-high by addint smsc,irq-active-high property. But i just copied
settings from those old Android kernels, and it just works.
 So, cleaning up and posting v6.
