From: Randy 'ayaka' Li <ayaka@soulik.info>

It doesn't work yet, I am suffering unknow power or
clock problem, but the vendor driver I post to ML
would work.

I want to put the implementation of those v4l2 ioctl
which related to device in echo device's files, but
the current inheritance looks ugly.

TODO:
qp table
