[PATCH, 0/6] HID-Sensors v3

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 

v1:
Base implementation for comments
