2021-06-13iio: accel: bma180/bmc150: Move BMA254 to bmc150-accel driverStephan Gerhold1-3/+3
Commit c1d1c4a62db5 ("iio: accel: bma180: BMA254 support") added BMA254 support to the bma180 driver and changed some naming to BMA25x to make it easier to add support for BMA253 and BMA255. Unfortunately, there is quite some overlap between the bma180 driver and the bmc150-accel driver. Back when the commit was made, the bmc150-accel driver actually already had support for BMA255, and adding support for BMA254 would have been as simple as adding a new compatible to bmc150-accel. The bmc150-accel driver is a bit better for BMA254 since it also supports the motion trigger/interrupt functionality. Fortunately, moving BMA254 support over to bmc150-accel is fairly simple because the drivers have compatible device tree bindings. Revert most of the changes for BMA254 support in bma180 and move BMA254 over to bmc150-accel. This has the following advantages: - Support for motion trigger/interrupt - Fix incorrect scale values (BMA254 currently uses the same as BMA250 but actually they're different because of 10 vs 12 bits data size) - Less code than before :) BMA250 could be potentially also moved but it's more complicated because its chip_id conflicts with the one for BMA222 in bmc150-accel. Perhaps there are also other register differences, I did not investigate further yet (and I have no way to test it).

2021-06-13iio: accel: bmc150: Add device IDs for BMA253Stephan Gerhold1-1/+1
BMA253 is mostly like BMA255 and has exactly the same register layout as used by the bmc150-accel driver as far I can tell. Making it work is as simple as adding new device IDs for it since it has the same chip_id = 0xFA (250) as BMA255 and others.

2021-06-13iio: accel: bmc150: Clarify combo modules in KconfigStephan Gerhold1-2/+5
The Kconfig option currently says that all Bosch accelerometers supported by the bmc150-accel driver are combo chips with both accelerometer and magnetometer. This is wrong: actually only BMC150 is such a combo. The BMA* variants only contain an accelerometer and the BMI055 actually is a accelerometer + gyroscope combo. Clarify this in the help text and also make the list of supported variants complete and sorted for consistency.

2021-05-10iio: hid-sensors: select IIO_TRIGGERED_BUFFER under HID_SENSOR_IIO_TRIGGERAlexandru Ardelean1-1/+0
During commit 067fda1c065ff ("iio: hid-sensors: move triggered buffer setup into hid_sensor_setup_trigger"), the iio_triggered_buffer_{setup,cleanup}() functions got moved under the hid-sensor-trigger module. The above change works fine, if any of the sensors get built. However, when only the common hid-sensor-trigger module gets built (and none of the drivers), then the IIO_TRIGGERED_BUFFER symbol isn't selected/enforced. Previously, each driver would enforce/select the IIO_TRIGGERED_BUFFER symbol. With this change the HID_SENSOR_IIO_TRIGGER (for the hid-sensor-trigger module) will enforce that IIO_TRIGGERED_BUFFER gets selected. All HID sensor drivers select the HID_SENSOR_IIO_TRIGGER symbol. So, this change removes the IIO_TRIGGERED_BUFFER enforcement from each driver.

commit 762227721fe6225be5b6d233ef681aea5871f5f3 "iio: accel: st_accel: handle deprecated bindings" attempted to be smart and let users use the old I2C driver and the new SPI driver, or the old SPI driver and the new I2C driver in combination for the LIS3LV02, and put the restrictions on the I2C and SPI subdrivers not not be combined with the old subdrivers. This doesn't work since the IIO ST accel top-level component selects the I2C and SPI subdrivers, resulting in the following Kconfig noise: warning: (IIO_ST_ACCEL_3AXIS) selects IIO_ST_ACCEL_I2C_3AXIS which has unmet direct dependencies (IIO && !SENSORS_LIS3_I2C && IIO_ST_ACCEL_3AXIS && IIO_ST_SENSORS_I2C) warning: (IIO_ST_ACCEL_3AXIS) selects IIO_ST_ACCEL_SPI_3AXIS which has unmet direct dependencies (IIO && !SENSORS_LIS3_SPI && IIO_ST_ACCEL_3AXIS && IIO_ST_SENSORS_SPI) (...)

This converts the KXSD9 driver to drop the custom transport mechanism and just use regmap like everything else. Tested-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2016-09-18iio: accel: kxsd9: Split out SPI transportLinus Walleij1-1/+9
This moves the KXSD9 SPI transport out to its own file and Kconfig entry, so that we will be able to add another transport method. We export the common probe and add a local header file for the functionality shared between the main driver and the transport driver. We make the SPI transport the default for the driver if SPI is available and the KXSD9 driver was selected, so the oldconfig upgrade path will be clear.

2016-08-21iio: accel: add support for the Domintech DMARD09 3-axis accelerometerJelle van der Waa1-0/+10
Minimal implementation of an IIO driver for the Domintech DMARD09 3-axis accelerometer. Only supports reading the x,y,z axes at the moment. Implementation based on the Android driver from the Acer Liquid E2 kernel sources. Signed-off-by: Jelle van der Waa <jelle@vdwaa.nl> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
