f1d8a071d4 counter: 104-quad-8: Add Generic Counter interface support
This patch adds support for the Generic Counter interface to the
104-QUAD-8 driver. The existing 104-QUAD-8 device interface should not
be affected by this patch; all changes are intended as supplemental
additions as perceived by the user.

Generic Counter Counts are created for the eight quadrature channel
counts, as well as their respective quadrature A and B Signals (which
are associated via respective Synapse structures) and respective index
Signals.

The new Generic Counter interface sysfs attributes are intended to
expose the same functionality and data available via the existing
104-QUAD-8 IIO device interface; the Generic Counter interface serves
to provide the respective functionality and data in a standard way
expected of counter devices.

0040a390d2 counter: Introduce the Generic Counter interface
This patch introduces the Generic Counter interface for supporting
counter devices.

In the context of the Generic Counter interface, a counter is defined as
a device that reports one or more "counts" based on the state changes of
one or more "signals" as evaluated by a defined "count function."

Driver callbacks should be provided to communicate with the device: to
read and write various Signals and Counts, and to set and get the
"action mode" and "count function" for various Synapses and Counts
respectively.

To support a counter device, a driver must first allocate the available
Counter Signals via counter_signal structures. These Signals should
be stored as an array and set to the signals array member of an
allocated counter_device structure before the Counter is registered to
the system.

Counter Counts may be allocated via counter_count structures, and
respective Counter Signal associations (Synapses) made via
counter_synapse structures. Associated counter_synapse structures are
stored as an array and set to the the synapses array member of the
respective counter_count structure. These counter_count structures are
set to the counts array member of an allocated counter_device structure
before the Counter is registered to the system.

A counter device is registered to the system by passing the respective
initialized counter_device structure to the counter_register function;
similarly, the counter_unregister function unregisters the respective
Counter. The devm_counter_register and devm_counter_unregister functions
serve as device memory-managed versions of the counter_register and
counter_unregister functions respectively.

One way to fix these warnings is to add additional braces like Clang
suggests; however, there has been a bit of push back from some
maintainers, who just prefer memset as it is unambiguous, doesn't
depend on a particular compiler version, and properly initializes all
subobjects [1][2]. Do that here so there are no more warnings.

447ccb4e08 iio: adc: qcom-spmi-adc5: Fix of-based module autoloading
The of_device_id table needs to be registered as module alias in order
for automatic module loading to pick the kernel module based on the
DeviceTree compatible. So add MODULE_DEVICE_TABLE() to make this happen.

20c89b4d1d iio: trigger: stm32-timer: fix build issue when disabled
This fixes a build issue when CONFIG_IIO_STM32_TIMER_TRIGGER isn't set but
used in stm32-dfsdm-adc driver (e.g. CONFIG_STM32_DFSDM_ADC is set):
ERROR: "is_stm32_timer_trigger" [drivers/iio/adc/stm32-dfsdm-adc.ko]
undefined!

There are two possible options to fix this issue:
- select IIO_STM32_TIMER_TRIGGER along with CONFIG_STM32_DFSDM_ADC.
  This is what's being done currently for CONFIG_STM32_ADC.
- stub "is_stm32_timer_trigger" function

Choice is made to stub this function as suggested in [1]. This is also
inspired by similar "is_stm32_lptim_trigger" function (see [2]) in
include/linux/iio/timer/stm32-lptim-trigger.h

Since imx7d_adc_remove() does exactly the same thing as
imx7d_adc_suspend() we can use the latter together with
devm_add_action_or_reset() to simplify the former. Rename
imx7d_adc_suspend() to imx7d_adc_disable() for clarity while at it.

edde945257 iio: dac: ad5758: Modifications for new revision
This patch will ensure compatibility with the new revision of the AD5758
dac converter. The modifications consist of removing the fault_prot_switch
function since this option is no longer available, and enabling the
ENABLE_PPC_BUFFERS bit in ADC_CONFIG register before setting the PPC
current mode.

The previous version of the chip was never released to customers
so there is no need to support it going forwards.
