Subject: util/superiotool: Add ITE IT8616E/IT8656E support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Datasheet is not publicly available. Derive which registers to dump from
IT8625E, since there are mainboards that can use either chip depending
on BOM configuration. Default values are taken from an HP 280 G2 running
a coreboot build that does not configure the Super I/O.
