Do you know that :
 1) anything under "---" in a commit message is thrown away
 2) after v2, we _both_ agreed that the accurate name is "cplds"
    which exactly what is in this patch
    (see device registering with lubbock_cplds).
 3) there is no more mention of "board" anywhere in the patch core

I might need help. As for the (sales), no comment.

I thought cplds were to be handled by an MFD driver.

Why ? I think things were clear that this driver handles the CPLDs on
lubbock board, namely u46 and u52. I don't understand what is wrong
with this patch so that you don't want to go forward.
