2018-07-07IIO: st_accel_i2c.c: Use probe_new() instead of probe()Nikolaus Voss1-3/+2
struct i2c_device_id argument of probe() is not used, so use probe_new() instead. Signed-off-by: Nikolaus Voss <nikolaus.voss@loewensteinmedical.de> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2018-07-07IIO: st_accel_i2c.c: Simplify access to driver dataNikolaus Voss1-34/+25
Use device_get_match_data API to simplify access to driver data. Let acpi_device_id table entries point to the same driver data as of_device_id table entries and uniquify access to driver data by using device_get_match_data API. Remove unused i2c_device_id .driver_data fields.

That change is necessary to add device-tree support in spi code otherwise the rest of the autodetection will fail since spi->modalias (and indio_dev->name) will be set using compatible string value that differs from standard sensor name Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@st.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2017-01-10iio: accel: st_accel: handle deprecated bindingsLinus Walleij1-0/+5
The earlier deployed LIS3LV02DL driver had already defined a few DT bindings that need to be supported by the new more generic driver and listed as compatible but deprecated bindings in the documentation. After this we can start to activate the new driver with the old systems where applicable. As part of this enablement: make us depend on the old drivers not being in use so we don't get a kernel with two competing drivers.

2016-07-04iio: accel: st_accel: Add lis3l02dq supportJonathan Cameron1-0/+5
Time to finally kill off the venerable (it was one of my first drivers) lis3l02dq driver in favour of adding support in the st sensors framework. This does loose us the event support that driver always had, but I think that will reappear at some point and in the meantime the maintenance advantages of dropping the 'special' driver for this one part outweigh the issues. It's worth noting this part is ancient and I may well be the only person who still has any on hardware running recent kernels. It has a few 'quirks'. - No WAI register so that just became optional. - A BDU option that really does block updates. Completely. Whatever you do, you don't get any more data with it set. It is documented the same as more modern parts but I presume they are actually clearing for updates after a read of both bytes! - Fixed scale. - It's too quick. Even at slowest rate (280Hz) I can't read out fast enough on my board (stargate 2) to beat new data coming in. Linus' repeat read patch doesn't help in this case. It just means I get 10 readings before dying... So in reality this will get used with software triggers only unless someone has this long out of production device on a quick board.

2014-07-12iio: st_sensors: add devicetree probing supportLinus Walleij1-0/+51
The I2C devices that make up the STMicroelectronics MEMS sensors may be sneakily enabled by cleverly giving the device node the same name as a string match from the platform device ID table. However the right method is to use the compatible string. On detection, the ST sensors use the ID string to probe and instatiate the right sensor driver, so pass the kernel-internal ID string in the .data field of the OF match table, and set the I2C client name to this name when a compatible match is used. This avoids having misc Linux-specific strings floating around in the device tree.
