Rob Herring 04dbd86539 dt-bindings: Fix paths in schema $id fields
The $id path checks were inadequately checking the path part of the $id
value. With the check fixed, there's a number of errors that need to be
fixed. Most of the errors are including 'bindings/' in the path which
should not be as that is considered the root.

Greg Kroah-Hartman 821f7ce79f First set of new device support, features and cleanups for IIO in the 5.6 cycle
New device support
 
 * ad7091r5 ADC
   - New driver with follow up patch adding scale and vref support.
   - DT bindings
 * ad7923
   - Support for ad7908, ad7918 and ad7928 added to driver.
 * bma180
   - Support the BMA254 accelerometer. Required fairly substantial rework
     to allow for small differences between this an existing parts.
 * bma400 accelerometer
   - New driver with follow up patch for regulator support.
   - DT bindings.
 * asc dlhl60d
   - New driver support this range of pressure and temperature sensors.
   - DT bindings.
 * ltc2496 ADC
   - New driver to support this ADC.
   - Split the existing LTC2497 driver generic component out and reuse.
   - DT bindings.
 * parallax ping
   - New driver supporting ultrasonic and laser tof distance sensors.
   - Bindings for these sensors.
 
 New features
 
 * core
   - New char type for read_raw returns, used for thermocouple types.
   - Rename read_first_n callback to read.   The reasons behind the original
     naming are lost to the mists of time.
 * ad799x
   - Allow pm_ops to disable device completely allowing regulator power down.
 * bma180
   - Enable basic regulator support.
 * dmaengine buffer
   - Report platform data alignment requirements via new ABI.
 * max31856
   - Add option to set mains filter rejection frequency and document
     new in_temp_filter_notch_center_frequency ABI.
   - Add support for configuring HW averaging (oversampling ratio)
   - Add runtime configuration of thermocouple type and document new ABI.
 * maxim-thermocouple
   - Add read only access to thermocouple type using new ABI, includes
     adding more specific compatibles to reflect which variant of the
     chip is being used.
 * mpu6050
   - Provide option to support the PMU9150 in package magnetometer directly
     rather than via auxiliary bus.
 * stm32_adc

  - DT bindings
* ad7923
  - Support for ad7908, ad7918 and ad7928 added to driver.
* bma180
  - Support the BMA254 accelerometer. Required fairly substantial rework
    to allow for small differences between this an existing parts.

  - Add read only access to thermocouple type using new ABI, includes
    adding more specific compatibles to reflect which variant of the
    chip is being used.
* mpu6050

    rather than via auxiliary bus.

Linus Walleij c1d1c4a62d iio: accel: bma180: BMA254 support
This adds support for the BMA254 variant of this
accelerometer. The only difference for the simple IIO
driver is that values are 12 bit and the temperature
offset differs by 1 degree.

Whilst wildcards in naming are normally frowned upon:

The cases where I have labeled variables "25x" is where the
models are identical, so as to make things easier for people
that want to add support for BMA253 and BMA255.

Miquel Raynal 1689387487 dt-bindings: iio: adc: max1027: Mark interrupts as optional
The chips have a 'start conversion' and a 'end of conversion' pair of
pins. They can be used but this is absolutely not mandatory as regular
polling is supported by the chip depending on its internal clocking
setup.

There is no physical reason to force the use of interrupts so turn
them optional.

Also, once the interrupt turned optional, these devices fit perfectly
the "trivial devices" described in the generic (yaml) bindings file, so
instead of converting this text file to json schema, we can just add
the relevant compatibles in:
Documentation/devicetree/bindings/trivial-devices.yaml.

Rob Herring f3dde260bb dt-bindings: Clean-up regulator '-supply' schemas
Regulator '*-supply' properties are always a single phandle, so
'maxItems: 1' or a $ref is not necessary. All that's needed is either
'true' or an optional 'description'. Following this clean-up, the
meta-schema will enforce this pattern.

There's one case in tree with 'innolux,n156bge-l21' having 2 phandles.
This appears to be a mistake or abuse of simple-panel as it's 2 different
voltage rails connected to 'power-supply'.

Greg Kroah-Hartman 9dc86c234e First set of IIO new device support, cleanups and features for the 5.5 cycle
Third version with the adis rework set dropped as better to just have
 a fresh version of that at some future date.
 
 The usual mixed backs of new device support being added to drivers,
 long term reworks continuing and little per driver cleanups and
 features.
 
 Also a few trivial counter subsystem tidy ups on behalf of William.
 
 Core new feature
 * Device label support.  A long requested feature no one got around to
   implementing before.  Allows DT based provision of a 'label' that
   identifies a device uniquely within a system.  This differs from existing
   'name' which is meant to be the part number.
 New device support
 * ingenic-adc
   - Support for the JZ4770 SoC ADC including bindings.
 * inv_mpu6050
   - Add support for magnetometer in MPU925x parts.
     Fiddly to do as this is actually a separate device sitting inside the
     package, but with the master device being able to schedule reads etc.
     Will only run if the auxiliary bus is not in use for any other devices.
 
 Features
 * ad7192
   - Userspace calibration controls to do zero and full scale.
 * st_lsm6dsx
   - Enable latched interrupts by default for sensors events with related clear.
   - Motion events and related wakeup source.  This needed quite a bit of
     refactoring as well.
 
 Cleanups and minor features
 * ad7192
   - sysfs ABI docs
 * ad7949
   - Remove code to readback configuration word as driver never actually enabled
     it.
   - Fix incorrect xfer length.  Not actually known to cause problems other
     than wasted bus usage.
 * adis16080
   - Replace core mlock usage with local lock with more appropriate scope.
 * adis16130
   - Remove pointless mlock usage.
 * adis16240
   - Remove include of gpio.h as no gpio usage.
