Replace the boolean is_smo8500_device variable with an acpi_type enum.

For now this can be either ACPI_GENERIC or ACPI_SMO8500, this is a
preparation patch for adding special handling for the KIOX010A ACPI HID,
which will add a ACPI_KIOX010A acpi_type to the introduced enum.

For stable as needed as precursor for next patch.

When VCNL4035 is enabled and IIO_BUFFER is disabled, it results in the
following Kbuild warning:

WARNING: unmet direct dependencies detected for IIO_TRIGGERED_BUFFER
  Depends on [n]: IIO [=y] && IIO_BUFFER [=n]
  Selected by [y]:
  - VCNL4035 [=y] && IIO [=y] && I2C [=y]

The reason is that VCNL4035 selects IIO_TRIGGERED_BUFFER without depending
on or selecting IIO_BUFFER while IIO_TRIGGERED_BUFFER depends on
IIO_BUFFER. This can also fail building the kernel.

Honor the kconfig dependency to remove unmet direct dependency warnings
and avoid any potential build failures.

When the command feature of the ADC is used, it is possible to program
the ADC, and specify at each step what input should be processed, and in
comparison to what reference.

This broke the AUX and battery readings when the touchscreen was
enabled, most likely because the CMD feature would change the VREF all
the time.

Now, when AUX or battery are read, we temporarily disable the CMD
feature, which means that we won't get touchscreen readings in that time
frame. But it now gives correct values for AUX / battery, and the
touchscreen isn't disabled for long enough to be an actual issue.

Set 10ms as minimum i2c slave configuration timeout since st_lsm6dsx
relies on accel ODR for i2c master clock and at high sample rates
(e.g. 833Hz or 416Hz) the slave sensor occasionally may need more cycles
than i2c master timeout (2s/833Hz + 1 ~ 3ms) to apply the configuration
resulting in an uncomplete slave configuration and a constant reading
from the i2c slave connected to st_lsm6dsx i2c master.

Since overrun interrupt support has been added, there's a regression when
two ADCs are used at the same time, with:
- an ADC configured to use IRQs. EOCIE bit is set. The handler is normally
  called in this case.
- an ADC configured to use DMA. EOCIE bit isn't set. EOC triggers the DMA
  request. It's then automatically cleared by DMA read. But the handler
  gets called due to status bit is temporarily set (IRQ triggered by the
  other ADC).

This is a regression as similar issue had been fixed earlier by
commit dcb10920 ("iio: adc: stm32-adc:
fix a race when using several adcs with dma and irq").
Issue is that stm32_adc_eoc_enabled() returns non-zero value (always)
since OVR bit has been added and enabled for both DMA and IRQ case.

Remove OVR mask in IER register, and rely only on CSR status for overrun.
To avoid subsequent calls to interrupt routine on overrun, CSR OVR bit has
to be cleared. CSR OVR bit cannot be cleared directly by software.
To do this ADC must be stopped first, and OVR bit in ADC ISR has
to be cleared.
Also add a check in ADC IRQ handler to report spurious IRQs.

The "cb_pcidas" driver supports asynchronous commands on the analog
output (AO) subdevice for those boards that have an AO FIFO.  The code
(in `cb_pcidas_ao_check_chanlist()` and `cb_pcidas_ao_cmd()`) to
validate and set up the command supports output to a single channel or
to two channels simultaneously (the boards have two AO channels).
However, the code in `cb_pcidas_auto_attach()` that initializes the
subdevices neglects to initialize the AO subdevice's `len_chanlist`
member, leaving it set to 0, but the Comedi core will "correct" it to 1
if the driver neglected to set it.  This limits commands to use a single
channel (either channel 0 or 1), but the limit should be two channels.
Set the AO subdevice's `len_chanlist` member to be the same value as the
`n_chan` member, which will be 2.

  perturb the SipHash state using fast, non-trivially predictable data,

  make any occasional memory leakage or brute-force attempt useless.

  The resulting code was verified to be very slightly faster on x86_64

Commit 21653a41 ("i2c: core: Call i2c_acpi_install_space_handler()
before i2c_acpi_register_devices()")'s intention was to only move the
acpi_install_address_space_handler() call to the point before where
the ACPI declared i2c-children of the adapter where instantiated by
i2c_acpi_register_devices().

But i2c_acpi_install_space_handler() had a call to
acpi_walk_dep_device_list() hidden (that is I missed it) at the end
of it, so as an unwanted side-effect now acpi_walk_dep_device_list()
was also being called before i2c_acpi_register_devices().

Move the acpi_walk_dep_device_list() call to the end of
i2c_acpi_register_devices(), so that it is once again called *after*
the i2c_client-s hanging of the adapter have been created.

This fixes the Microsoft Surface Go 2 hanging at boot.
