[PATCH 0/7] mfd / platform: cros_ec: move cros_ec sysfs attributes to its own drivers.

[Enric Balletbo i Serra]

Hi,

This is another patchset to try to cleanup a bit more the crossed
references for cros-ec driver between the MFD and the platform/chrome
subsystems.

The purpose of these patches is get rid of the different cros-ec attributes
from mfd/cros_ec_dev to its own sub-driver in platform/chrome. cros_ec_dev
continues instantiating the sub-devices but the sysfs attributes are owned
by the platform driver.E.g. The lightbar driver should own his sysfs
attributes and be instantiated only if the Embedded Controller has a
lightbar.

The patchset also adds the documentation of the sysfs attributes.

Waiting for your feedback. Best regards,
 Enric
