At a slight footprint cost (24 vs 32 bytes), mutexes are more optimal
than semaphores; it's also a nicer interface for mutual exclusion,
which is why they are encouraged over binary semaphores, when possible.

For both v_sem and z_sem, their semantics imply traditional lock
ownership; that is, the lock owner is the same for both lock/unlock
operations. Therefore it is safe to convert.

Merge tag 'iio-for-5.5b' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Second set of IIO + counter new device support, features etc for the 5.5 cycle.

Note two merge commits in here, both for immutable branches based
of 5.4-rc1.
1. Ti eqep driver because of some file moves in precursor patches.
   I suspect no one else will pull this one.
2. ab8500 refactor as changes in power supply, hwmon and mfd trees.
   This may come via numerous trees as well as IIO.

Counter subsystem related
* ti eqep
  - New device support with bindings.
  - Includes prior file move to reflect more general use of ti-pwmss.
* Counter core
  - simplify count_read and count_write callbacks + document change.
  - fix a typo in docs.

Various subsystems related
* AB8500
  - ab8500_btemp driver converted to be an IIO consumer driver.
  - ab8500_charger driver converted to be an IIO consumer driver.
  - ab8500_fg fuel gauge driver converted to be an IIO consumer driver.
  - ab8500 hwmon driver converted to be an IIO consumer driver.
  - mfd bindings augmented with the adc channels to make the above work.
  - drop original mfd driver.

New device support
* ab8500
  - new ADC driver used by the above other subystems via the IIO consumer
    interface.
* adux1020 photometric sensor
  - new driver and dt bindings.
* fxos877cq
  - new driver for this simple(ish) IMU with DT bindings.
* intel_mrfld_adc
  -  new driver for the ADC found on Intel Merrifield platforms.
* ltc2983
  - new driver for this multi-sensor type temperature interface.
    Includes complex DT bindings.
* max1027
  - support for 12 bit devices, max1227, max1229 and max1231 + add to trivial
    bindings.
* st_lsm6dsx
  - support for the LSM6DS0 6 axis MEMs sensor.
    Note different from the LSM6DSO which the driver already supports *sigh*
  - support for the LSM6DSRX 6 axis MEMs sensor.

Features and cleanups
* ad7303
  - replace use of core mlock with a local lock with cleanly defined scope.
* ad9834
  - add a check for devm_clk_get failing.
* at91-sama5d2
  - tidy up a 0 as NULL warning.
* bmp280
  - endian type tidy ups.
  - use bulk regulator ops for a small reduction in code.
  - use devm_add_action... to simplify error path handling.
* exynos
  - drop stray semicolon.
  - use devm_platform_ioremap_resource to reduce boilerplate.
* hx711
  - various tricks to improve the frequency of read out possible.
* max1027
  - debugfs support.
  - make interrupts optional.
  - reset at probe to get clean state.
  - refactors to allow addition of new device support.
* maxim thermocouple
  - drop an unneeded semicolon.
* mb1232
  - yaml binding conversion.
* mcp320x
  - tidy up an endian types in cast warning.
* meson_saradc
  - use devm_platform_ioremap_resource to reduce boilerplate.
* mpu3050
  - make a poison value explicity big endian to supress a warning.
* pulsedlight v2
  - endian type tidy ups.
* sgp30
  - drop an excess semicolon.
* sps30
  - make truncation explicit with masking to clean up a warning.
* st sensors
  - drop gpio include as none of these support gpios.
* st_lsm6dsx
  - tidy up some alignment issues.
  - refactors to allow addition of new device support.
    * allow varients of irq related reg definitions.
    * avoid accessing active-low, open-drain regs if not provided.
    * allow varients of bdu/boot and reset regs.
    * allow for enabling or disabling wakeup sources through platform
      data (seems someone still uses this).
  - enable wake-up events for LSM6DS0
  - use the drdy mask to avoid some invalid samples during initial start
    of sensor.
  - Add support to trim the timestamp.
* stm32_adc
  - kernel-doc fixes.
* stm32_dac
  - power management support.
* stmpe-adc
  - Fix endian type of local variable.
* twl4030
  - use false / true instead of 0 / 1 for booleans.
* xilinx-xadc
  - use devm_platform_ioremap_resouce to reduce boilerplate.
* zpa2326
  - reorganise buffer handling setup to be more consistent.

Fixes (mostly recent additions)
* cpcap-adc
  - Fix mising IRQF_ONESHOT that would cause warnings to be printed.
* st_lsm6dsx
  - Sanity check the read_fifo pointer is set.
  - use locked read and update functions to prevent some races.
  - avoid accessing enable_reg if not provided.
  - take a lock to prevent a race in updating the config.
  - kernel-doc fixes.
  - document wakeup-source property in dt binding.
  - fix lsm9ds1 gyro gain definitions.
