2017-01-10iio: accel: st_accel: handle deprecated bindingsLinus Walleij1-0/+9
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/+1
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.

2015-12-01Merge tag 'iio-for-4.5a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-nextGreg Kroah-Hartman1-0/+1
Jonathan writes: First set of new device support, features and cleanups for IIO in the 4.5 cycle Usual mixed bag, but the big item perhaps in this series is the DMA buffer support added by Lars-Peter Clausen. It's been in the works for a long time and it will be interesting to see what hardware support shows up now that this is available. New core features + associate cleanup. * Add generic DMA buffer infrastructure * Add a DMAengine framework based buffer Also associated minor changes. - Set the device buffer watermark based on the minimum watermark for all attached buffers rather than just the 'primary' one. - iio_buffer_init - only set the watermark default if one hasn't already been provided. This allows simple support for devices with a fixed watermark. - read only attribute for watermark on fixed watermark devices. - add explicit buffer enable/disable callbacks to allow the buffer to do more than trivial actions when it is being turned on and off. * IIO_VAL_INT support in write_raw_get_fmt function. New device support * Freescale MMA7455/7456L accelerometers * Memsic MXC6255XC accelerometer * ST lis2dh12 accelerometer * TI ADS8688 ADC * TI Palamas (twl6035/7) gpadc New driver features * mma8452 - support either of the available interrupt pins to cope with the case where board layout has lead to a particular one being connected. Staging graduation * Dummy driver - this driver acts as both an example and a test device for those with out hardware to develop userspace code against. Cleanups and minor bits and bobs. * treewide - Sort out the ordering of iio_device_register/unregister vs runtime pm function calls so that it's all nice and consistent and not race prone. - Check sscanf return values. None of the cases will actually happen as the strings are supplied internally, but best to be consistent on this. * ad7780 - switch over to the gpio descriptor interface and remove the now unused platform data which gets rid of a header entirely. * ad7793 - drop a pointless else statement. * at91_adc - Swap kmalloc_array in for a kmalloc doing the same job. * dummy - get rid of some commented out lines that snuck in during the move of the driver. * lm3533-als - Print an error message on provision of an invalid resistance. * mcp320x - Add compatible strings with vendor prefix and deprecate those with no vendor prefix. * mxs-lradc - Use BIT macro in various places rather than shifted ones. * pa12203001 - Power off the chip if the registration fails. * pulsedlight-lidar-lite - add runtime PM support. * xilinx XADC - constify an iio_buffer_setup_ops structure.
