v9:
- change commit messages
- Trivial changes suggested by Jiri
v8:
- Rebase against staging-next
- Kernel doc generation warnings
- Makefile single line/driver
- Some stubtle warnings on some platforms
v7:
- Changes related to pow function
- channel spec constant for sensors
- Remove additional init/exit functions
- Error handling for invalid report ids
v6:
- Fix kernel oops during mfd_add_device on some devices
- Jonathan's suggested change to remove private member from common to associate a \
sensor type state. The sensor state contains a member to hold all common attributes
- Fix issue with decimal point interface
v5:
- Documentation changes as suggested by Peter Meerwald and Jonathan Cameron
- Change Kconfigs to corrected typo pointed by David Herrmann (3G to 3D \
(3-dimension))
- Sensor framework changes for comments from Jonathan
-- Modified help to for HID_SENSOR_HUB
-- Removed all size restrictions (#define ...)
-- Use of kasprintf for driver names
-- Removed defines for reports
-- kernel doc for structures
-- Embed pending structure to sensor hub data structure and removed dynamic \
allocation of requests
-- Removed unused structure fields
-- Blank line before returns
-- Shorter defines for HID sensor usage id defines
- Common attributes and triggers
-- Removed maximunm sampling freq restrictions
-- Allow decimal format from channel raw read calls with micro fractions
-- Can't get arround FW quirk config with the information from report
- Accelerometer 3D support
-- Changed defines for channels to enums
-- Added hysteresis and sampling frequency to channels definition
-- Simpliefiled state structure
-- Removed casts
-- Error handling
-- Removed channel mask settings
-- Changed to module_platform_driver
v4:
Addressed comments from Lars-Peter Clausen and Jiri Kosina.
- Added Documentation/hid/hid-sensor.txt
- As suggested, created iio/common folder which can contain common code for iio \
sensor driver.This contain common module to process trigger and \
attributes
- Removed empty callback functions.
- Duplicating channel structure for an IIO driver instance.
v3 :
- Using TRIGGERRED BUFFER
- Using MFD framework
The sensor hub driver is submiited to drivers/hid. This contains core processing of \
hid sensor usage table, registers as an hid driver and adds registration function \
for routing data to individual sensor driver. So core driver independent of user \
mode interface method (IIO/input etc.)
- Submiiting four drivers for Accelerometer-3D, Gyro-3D, Compass-3D and ALS. These \
uses IIO triggered buffer interface. They are childrens of hid sensor hub driver.
They reside in iio/accel, iio/gyro iio/magnetometer and iio/light.
- Still using driver/staging/iio. Not able to test with driver/iio.
v2 :
- Replaced Ring-SW with KFiFO
- Accel-3d, Gyro-3D and Compass-3D uses 3 different channels for X, Y and Z
- SysFS (
--- Changed "polling_interval" to sampling_frequency (IIO_DEV_ATTR_SAMP_FREQ) with \
units HZ
--- Changed "sensitivity" to hyst_raw, which is already used by some ADC modules
--- Removed "Activate". No longer need this. Using trigger state to \
activate/deactivate )
- Removed sysfs attributes for "xxx_offset". Instead using mask 0 in read_raw. So \
each sensor have only channels, sampling_frequency and hyst_raw as the ABI.
- Additional patch to enable ST Micro sensor hub-
