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.
Regards, Thierry
