[PATCH v4 0/6] platform/chrome: cros_ec debugfs and sysfs updates

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

Hi,

This is a four patchset that introduces some cros_ec debugfs and sysfs
updates. This version is practically the same as version 3, it only
fixes the issue pointed by Gwendal to only allocate one extra sensor
intead of two.

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
