iio: st_sensors: drop ACPI_PTR() and CONFIG_ACPI guards The complexity of config guards needed for ACPI_PTR() is not worthwhile for the small amount of saved data. This example was doing it correctly but I am proposing dropping this so as to reduce chance of cut and paste where it is done wrong. Also drop now unneeded linux/acpi.h include.

iio: st_sensors: remove st_sensors_power_disable() function This change converts the st_sensors_power_enable() function to use devm_add_action_or_reset() handlers to register regulator_disable hooks for when the drivers get unloaded. The parent device of the IIO device object is used. This is based on the assumption that all other devm_ calls in the ST sensors use this reference. This makes the st_sensors_power_disable() un-needed. Removing this also changes unload order a bit, as all ST drivers would call st_sensors_power_disable() first and iio_device_unregister() after that.

iio: st_sensors: disable regulators after device unregistration Up until commit ea7e586bdd331 ("iio: st_sensors: move regulator retrieveal to core") only the ST pressure driver seems to have had any regulator disable. After that commit, the regulator handling was moved into the common st_sensors logic. In all instances of this regulator handling, the regulators were disabled before unregistering the IIO device. This can cause issues where the device would be powered down and still be available to userspace, allowing it to send invalid/garbage data. This change moves the st_sensors_power_disable() after the common probe functions. These common probe functions also handle unregistering the IIO device.

Let's bring them back to nearer the ideal. Identified with the include-what-you-use tool and careful checking of its suggestions. Note I haven't been particularly aggressive here, so this is just the cases where the include obviously isn't needed rather than the more subtle corners.

iio: accel: st_accel: Add lis3l02dq support 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.

iio: st_sensors: add devicetree probing support 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.

iio:st_sensors fix build when !CONFIG_IIO_TRIGGER Partly a case of removing unused headers and partly a case of ifdefing out the iio_trigger_ops structures. This has come about because of an 'unusual' separation of code in this driver.
