Hello,
Thanks to new datasheets published on http://linux.via.com.tw we can now add
support for VX800/VX820 chipsets.
If anyone has the hardware, please test the patch in attachment. Some simple
test with i2cdump should be enough the hardware controller is same as on other
chipsets.

Thank you,
Thanks,
Rudolf
