[alsa-devel] [PATCH 00/10] Move part of cros-ec out of MFD subsystem

[Enric Balletbo i Serra]

Hi,

This is the first attempt to clean up a bit more the cros-ec drivers
to have a better separation on what is part of the MFD subsystem and what
is part of platform/chrome.

It'd be really nice have some reviews, acks and tested on different
platforms from the chromiumos people before merge all this patchset, as
this moves a lot of code.

The major changes introduced by this patchset are:
1. Move the core driver to platform/chrome, as is not really related to
an MFD device driver.
2. Create a new misc chardev driver to replace the chardev bits from
cros-ec-dev (MFD)
3. Added some convenience structs in cros-ec-dev (MFD) to easy add more
subdrivers and avoid to add more boiler plate.

Once applied we have moved all the code to platform/chrome except the
cros-ec-dev driver, which is the one that instantiates the different
subdrivers as cells of the MFD device.

I tested the following patches on Veyron, Kevin, Samus, Peach Pi and
Peach Pit without noticing any problem, but they would need a lot of
more tests. I'll continue testing while the reviewing process of this
patchset.

Waiting for your feedback,
 Enric
