Modify management of drdy line and status register in order to support
LIS2DW12 device
Changes since v1:
- remove drdy_irq parameter from LPS001WP settings since the sensor
does not support data-ready interrupts
Lorenzo Bianconi (5):
iio: st_sensors: decouple irq1 configuration parameters from the irq2
ones
iio: st_sensors: do not always write enable_axis register
iio: st_sensors: add register mask for status register
iio: accel: add support to LIS2DW12
dt-bindings: iio: accel: add LIS2DW12 sensor device binding

Separate data-ready configuration parameters for INT1 and INT2 pins in
st_sensor_data_ready_irq data structure. That change will be use to
properly support LIS2DW12 accel sensor.

Unfortunately I'll have to hold this series for now as the 3/4 wire
patch need for the latter part of the series hasn't yet made it

Let me know if I seem to have forgotten it.
Thanks,

Unfortunately I'll have to hold this series for now as the 3/4 wire
patch need for the latter part of the series hasn't yet made it

Let me know if I seem to have forgotten it.
Thanks,

New devices (e.g. LIS2DW12) enable all axis by default and do not export
that capability in register map. Check if the enable_axis register
address has been declared in st_sensor_settings map in order to verify if
the driver needs to enable all sensor axis

* [PATCH v2 3/5] iio: st_sensors: add register mask for status register
@ 2017-08-17 17:37 ` Lorenzo Bianconi
0 siblings, 0 replies; 20+ messages in thread
From: Lorenzo Bianconi @ 2017-08-17 17:37 UTC (permalink / raw)
To: jic23; +Cc: linux-iio, linus.walleij, lorenzo.bianconi, devicetree
Introduce register mask for data-ready status register since
pressure sensors (e.g. LPS22HB) export just two channels
(BIT(0) and BIT(1)) and BIT(2) is marked reserved while in
st_sensors_new_samples_available() value read from status register
is masked using 0x7.
Moreover do not mask status register using active_scan_mask since
now status value is properly masked and if the result is not zero the
interrupt has to be consumed by the driver. This fix an issue on LPS25H
and LPS331AP where channel definition is swapped respect to status
register.
Furthermore that change allows to properly support new devices
(e.g LIS2DW12) that report just ZYXDA (data-ready) field in status register
to figure out if the interrupt has been generated by the device.
Fixes: 97865fe41322 (iio: st_sensors: verify interrupt event to status)

Introduce register mask for data-ready status register since
pressure sensors (e.g. LPS22HB) export just two channels
(BIT(0) and BIT(1)) and BIT(2) is marked reserved while in
st_sensors_new_samples_available() value read from status register
is masked using 0x7.
Moreover do not mask status register using active_scan_mask since
now status value is properly masked and if the result is not zero the
interrupt has to be consumed by the driver. This fix an issue on LPS25H
and LPS331AP where channel definition is swapped respect to status
register.
Furthermore that change allows to properly support new devices
(e.g LIS2DW12) that report just ZYXDA (data-ready) field in status register
to figure out if the interrupt has been generated by the device.
Fixes: 97865fe41322 (iio: st_sensors: verify interrupt event to status)

Hi Jonathan,
please ignore v2 series, I will send a v3 based on an irq fix for
LIS3MDL magn sensor.
Have a nice vacation :)
