When the image size (bytesperline*height) is not multiple
of PAGE_SIZE, v4l2 rounded the required buffer size to
be multiple of PAGE_SIZE. This prevented user space
to store images directly into userptr buffers which were
not multiple of PAGE_SIZE. This constraint is removed.
The start address is still assumed to be required

the offset between different buffers is page-aligned.

This adds an soc-camera / v4l2-subdev driver for the RJ54N1CB0C CMOS camera
sensor from Sharp. The sensor is very picky about initialisation and
configuration sequences. The driver limits artificially maximum window size by
800x600, although the sensor supports 1600x1200. Sizes above 800x600 don't seem
to work correctly, besides, examples from the system integrator use sizes above
640x480 only for still photography. Unfortunately, I had to use "magic"
register-value pairs for undocumented and "reserved" registers. This version of
the driver also omits some functionality, like cropping, which hasn't been
sufficiently tested yet and will be added later.

responding properly but all other registers returning the same value
(0x13 and 0x5 have been observed). This state will cause proper detection of
'885 vs. '887 vs. '888 to fail and the chip won't respond to get configured
properly anyway. I have no method of reseting the core to a working state at
this time; but I didn't try too hard to work one out either. The problem
likely only occurs in development. I suspect configuring the SYS PLL VCO to

IR controllers
2. possibly port it to the cx18 module for the CX23418 IR controller

Seems that the reference design used for the KWorld 2800d switched from the
em2860 to em2862, so we need to add the new USB id (and the i2c hash remains
so all we need is the default em2862 id.
Thanks to Ian Young for reporting the issue and testing the fix.
