Can you provide a datasheet for this part? I am surprised by the page
size. In general anyway, it's best to provide a link when adding
support for a new component.

Also, for your two series, no need to resend this time, but please use
git-format-patch and git-send-email to create your series, so that all
the patches are answers of the cover letter. It helps keeping all
patches and answers in the series packed together.

Thanks!
Miquèl
