[PATCH v3 0/6] platform/chrome: cros_ec debugfs and sysfs updates

[Enric Balletbo i Serra <enric.balletbo@collabora.com>]

Hi,

This is a third patchset that introduces some cros_ec debugfs and sysfs
updates. Some patches were send before but never merged and some others
are new.

First patch was already sent [1] but did not receive feedback so I am
resending it. Needs to go through platform/chrome tree and can be
picked without dependencies.

Patches 2 to 4 are cleanups of current code, basically is the
implementation of the changes suggested by Andy Shevchenko on the first
series. Again these must go through platform/chrome tree.

In Patch 5 I added a missing define, so now this patch can be picked
without any dependency, although now needs the ack from mfd and
platform/chrome maintainer as touches both sub-systems.

Finally, patch 6 was already sent [2] but now needed to be reworked due
the split of the cros_ec_devs in two parts [3]. This patch touches
platform/chrome and mfd so we will probably need an immutable branch.
This version also include a fix found by Gwendal.

Best regards,
  Enric
