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 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
Regards,
Thierry
