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). [1] https://lkml.org/lkml/2017/11/20/408 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 Enric Balletbo i Serra (1): platform/chrome: cros_ec_lpc: Register the driver if ACPI entry is missing.
