Hi,
This series enables a driver for a legacy accelerometer driver used on Chromebook devices with older EC firmware.
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).
The last patch is the code used to register this driver if the usual way of registering the croc_ec sensors hub fails. In this case, the 2 accelerometers (base and lid) are registered using mfd_add_devices(). As there is work in progress to remove calls to mfd_add_devices() from cros_ec_dev.c, this code is in a separate patch with the idea to make that easier.
Changes in v3: - Use kernel-doc notation for function headers - Add more comment to sensor ID sysfs attribute documentation - Restore accidentaly 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 hamdle timestamp copy into capture buffer - Added missing sysfs attribute documentation - Few cosmetic changes here and there
