Subject: [PATCH v3 0/4] Add support for cros-ec-sensors

Hi,

This is the third patchset to add support for the sensors behind the ChromeOS
Embedded Controller.

This version has only the patches to support common functions and 3d
contiguous sensors like Accelerometers, Gyroscope and Magnetometer that are
presented by the ChromeOS EC Sensor hub. The patches were tested on an Oak board.

The code was checked out from the ChromeOS v3.18 tree and forward ported to
mainline solving all the conflicts and build issues. I splitted the code in
single patches that have sense by themselves in order to avoid the chances
to fail.

Note that the patches depends on this [1] to apply and work.

Waiting for your reviews and feedback.

Changes since v2 (requested by Guenter Roeck and Jonhatan Cameron)
  - Rebased and fix build error.
  - Include a list of possible values in the description of location attr.
  - Fix some typos.
  - Remove id sysfs entry.
  - Skip filling by zero structure parameters that already zero'd.
  - Order includes alphabetically.
  - Propagate error codes.

Changes since v1 (requested by Peter Meerwald-Stadler and Jonhatan Cameron)
  - Check kernel-doc documentation and 
  - Bring some patches together.
  - Fix some spelling mistakes.
  - Include ABI documentation.
  - Be more careful with buffer sizes (sprintf -> snprintf)
  - Add cros_ec_sensors prefix to all function.
  - Check return values on some functions.

Best regards,

    Sensor Hub.
