13d4f9df33 iio: adc: aspeed: Add func to set sampling rate. 
Add the function to set the sampling rate and keep the sampling period
for a driver used to wait the fresh value.
In addition, since the ADC clock is required when initializing the ADC
device, move clk_prepare_enable ahead of the initialization phase.

90f9647753 iio: adc: aspeed: Fix the calculate error of clock. 
The ADC clock formula is
ast2400/2500:
ADC clock period = PCLK * 2 * (ADC0C[31:17] + 1) * (ADC0C[9:0] + 1)
ast2600:
ADC clock period = PCLK * 2 * (ADC0C[15:0] + 1)
They all have one fixed divided 2 and the legacy driver didn't handle it.
This patch register the fixed factory clock device as the parent of ADC
clock scaler to fix this issue.

eaa74a8d51 iio: adc: aspeed: Restructure the model data 
This patch refactors the model data structure to distinguish the
function form different versions of aspeed ADC.
- Rename the vref_voltage to vref_fixed_mv and add vref_mv driver data
When driver probe will check vref_fixed_mv value and store it to vref_mv
which isn't const value.
- Add num_channels
Make num_channles of iio device can be changed by different model_data
- Add need_prescaler flag and scaler_bit_width
The need_prescaler flag is used to tell the driver the clock divider needs
another Prescaler and the scaler_bit_width to set the clock divider
bitfield width.

The regulator_bulk_disable() is passed on a devm_add_action_or_reset() hook

The driver has both I2C and SPI hooks inside, so all these can be removed.

9678844430 staging: iio: ad9832: convert probe to device-managed 
This change does a conversion of the driver to use device-managed init
functions. The 2 regulators and the clock inits are converted to use
devm_add_action_or_reset() callbacks for de-initializing them when the
driver unloads.

And finally the devm_iio_device_register() function can be use to register
the device.

The remove hook can finally be removed and the spi_set_drvdata() call can
also be removed as the private data is no longer used.

8940de2e48 iio: adc: at91-sama5d2_adc: convert to platform specific data structures 
Convert the driver to platform specific structures. This means:
- create a register layout struct that will hold offsets for registers
- create a platform struct that will hold platform information (number of
channels, indexes for different channels and pointer to layout struct)
- convert specific macros that are platform dependent into platform variables

This step is in fact a no-op, but allows the driver to be more flexible
and for future enhancement including adding new platforms that are partly
compatible with the current driver and differ slightly in register layout
or capabilities for example.

The hw_init hardware init call must happen after the clock is prepared and
enabled. Otherwise, writing to the registers might lead to a block or
external abort.

25d4abbf3d iio: ltc2983: fail probe if no channels are given 
If there are no channels defined in the devicetree, there's no point in
probing the device. We were actually requesting a zero sized 'kmalloc'
array but since we were not touching the ZERO_SIZE_PTR afterwards,
nothing bad was actually happening. Hence this is not really a fix but
rather an improvement.

26df977a90 iio: ad5770r: make devicetree property reading consistent 
The bindings file for this driver is defining the property as 'reg' but
the driver was reading it with the 'num' name. The bindings actually had
the 'num' property when added in
commit ea52c21268 ("dt-bindings: iio: dac: Add docs for AD5770R DAC")
and then changed it to 'reg' in
commit 2cf3818f18 ("dt-bindings: iio: dac: AD5570R fix bindings errors").
However, both these commits landed in v5.7 so the assumption is
that either 'num' is not being used or if it is, the validations were not
done.

Anyways, if someone comes back yelling about this, we might just support
both of the properties in the future. Not ideal, but that's life...

1d761ca978 iio: gyro: remove dead config dependencies on INPUT_MPU3050 
Commit b1fe0cf06f ("Input: delete MPU3050 driver") deletes the superseded
MPU3050 driver and its corresponding config INPUT_MPU3050.

The dependencies on the superseding driver in ./drivers/iio/gyro/Kconfig
to ensure that the two drivers are not built into the same kernel is a dead
dependency and not required anymore.

So, remove those config dependencies on INPUT_MPU3050 for MPU3050_I2C.

This issue was detected with ./scripts/checkkconfigsymbols.py.

e426965154 iio: st_sensors: remove reference to parent device object on st_sensor_data 
The idea behind it, is that all devm_ calls in ST sensors are bound to the
parent device object.

However, the reference to that object is kept on both the st_sensor_data
struct and the IIO object parent (indio_dev->dev.parent).

This change only adds a bit consistency and uses the reference stored on
indio_dev->dev.parent, to enforce the assumption that all ST sensors' devm_
calls are bound to the same reference as the one store on st_sensor_data.
