Subject: [PATCH v2 0/5] hwmon: (sch5627) Make limit registers writable

This patch series adds support for writing the limit registers on
the sch5627. The first two patches fix the handling of the LOCK bit
inside the sch5627 control registers. The following two patches
introduce regmap support in order to use regcache for caching the
register values. The last patch updates the documentation regarding
the behaviour of the limit registers.

All patches have been tested on a Fujitsu Esprimo P720.
