[PATCH v5 0/3] platform/chrome: Support for cros_ec_accel_legacy driver

[Thierry Escande]

Hi,

This series enables the legacy accelerometer driver used on Chromebook
devices with older EC firmware.

The cros_ec_accel_legacy driver itself is no more part of this patchset
as it has already been merged in mainline. This patchset still contains
the patch that registers the cros_ec_accel_legacy driver if the usual
way of registering the croc_ec sensors hub fails. This patch has been
rebased on top of [1].

In addition to the cros_ec_accel_legacy driver, this series contains a
fix that registers the cros_ec_lpc driver on Chromebook devices that
does not have the GOOG0004 ACPI entry. In such case, the driver register
the device itself. This series also adds support to the cros_ec_lpc
driver for Glimmer based devices (Lenovo Yoga 11e).

Changes in v5:
- Remove the driver which is already merged
- Rebased on top of patchset [1]

Changes in v4:
- Use correct bitmask for scale channel specification
- Use precomputed scale factor value

Changes in v3:
- Use kernel-doc notation for function headers
- Add more comment to sensor ID sysfs attribute documentation
- Restore accidentally deleted comment for IIO_CHAN_INFO_CALIBBIAS handling in
  iio_info write_raw() callback

Changes in v2:
- Reorganize code to avoid forward declarations
- Simplify capture buffer declaration (also helps to remove forward
  declarations)
- Make use of iio_push_to_buffers_with_timestamp() and let the
  framework handle timestamp copy into capture buffer
- Added missing sysfs attribute documentation
- Few cosmetic changes here and there
