Jonathan writes:
Second set of new device support, cleanups and features for IIO in the 5.8 cycle
Usual mixed back but with a few subsystem wide or device type
wide cleanups.
New device support
* adis16475
- New driver supporting adis16470, adis16475, adis16477, adis16465,
adis16467, adis16500, adis16505 and adis16507.
Includes some rework of the adis library to simplify using it
for this new driver.
* ak8974
- Add support for Alps hscdt008a. ID only. Related patches add support
for scale.
* atlas-sensor
- Add support for RTD-SM OEM temperature sensor.
* cm32181
- Add support for CM3218 including support for SMBUS alert via
ACPI resources.
* ltc2632
- Add support for ltc2634-12/10/8 DACS including handling per
device type numbers of channels.
Major Features
* cm32181
- ACPI bindings including parsing CPM0 and CPM1 custom ACPI tables.
Includes minor tidy ups and fixes.
* vcnl4000
- Add event support
- Add buffered data capture support
- Add control of sampling frequency
Cleanups and minor fixes.
* core
- Trivial rework of iio_device_alloc to use an early return and
improve readability.
- Precursors to addition of multiple buffer support. So far
minor refactoring.
* subsystem wide
- Use get_unaligned_be24 slightly improve readability over open
coding it.
* adis drivers
- Use iio_get_debugfs_dentry access function.
* bh1780, cm32181, cm3232, gp2ap02a00f, opt3001, st_uvis25, vl6180,
dmard06, kxsd9
- Drop use of of_match_ptr to allow ACPI based probing via PRP0001.
Part of clear out of this to avoid cut and paste into new drivers.
* ad5592r, ad5593r
- Fix typos
* ad5933
- Use managed interfaces to automate error handling and remove.
* ak8974
- Fix wrong number of 'real bits' for buffered data.
- Refactor to pull measurement code out as separate function.
bmp280
- Fix lack of clamp on range during data capture.
* at91-sama5d2_adc
- Handle unfinished conversions correctly.
- Allow use of triggers other than it's own.
- Reorganize buffer setup and tear down as part of long running
subsystem wide rework.
* ccs811
- Add DT binding docs and match table.
- Support external reset and wakeup pins.
* hid-sensors
- Reorganize buffer setup and tear down as part of long running
subsystem wide rework.
* ltr501
- Constify some structs.
* vcnl4000
- Fix an endian issue by using explicit byte swapped i2c accessors.
