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

mfd: cros_ec: use devm_mfd_add_devices.
mfd / platform: cros_ec: move lightbar attributes to its own driver.
mfd / platform: cros_ec: move vbc attributes to its own driver.
mfd / platform: cros_ec: move debugfs attributes to its own driver.
mfd / platform: cros_ec: move device sysfs attributes to its own
driver.
mfd / platform: cros_ec: instantiate only if th EC has a VBC NVRAM.
platform/chrome: cros_ec_lightbar: instantiate only if the EC has a
lightbar.
