Merge tag 'iio-for-5.9b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

Second set of new device support, cleanups etc for IIO/Counters in the 5.9 cycle

There are two merge commits in here of immutable branches that may
also be picked up through other trees (clocksource and input)

I've put a few late breaking fixes in here that aren't worth rushing
in before the  merge window.  One major fix for an issue introduced
in the last set that can result in devices not having their parent set.

This set is dominated by W=1 cleanups from Lee Jones. I won't list them
all separately.  They are mostly:
* Kernel doc fixes
* Unused variable removal.
* Suppression of unused stuff that is static in headers.

Counters subsystem
* atmel-tcb
  - New counter driver after various cleanups of existing tcb code and bindings.

Device support
* stk311
  - Trivial addition of ID for STK311-X variant.

yaml conversions
* kionix,kxsd9
* ti,ads8688

Features
* jz47xx
  - Add support for touch screen channels. In this particular case the
    boards in question actually wire a joystick to them so we want them
    as simple voltage channels. The joystick driver will probably go
    via the input tree.

Cleanups + fixes
* core
  - A rebase issue in recent major refactoring dropped the assignment of
    of the device parent in the core. Put it back.
* ad5592r
  - Fix unbalanced mutex unlocks in *_read_raw()
* ad7124
  - Move chip ID and name to the chip_info table plus add a read of the
    revision register to check the device is working during probe.
* ad7192
  - Ridy up ordering to put the match table near the end fo the file where it
    is used.
* lsm6dsx
  - Reset the hardware timestamp after a resume to avoid an issue with
    missaligned timestamps after suspend.
* jz47xx
  - Error checks on clk_enable() calls.
  - xlate callaback to find channel index.
  - Use separate chan_spec arrays for different variants rather than
    parts of a single list.  Simplifies code.

A neater approach would be to cleanup the ad5592r_read_raw(), but that
would make this patch more difficult to backport to stable versions.

Series needed as base for a clocksource tree hence immutable branch

Immutable branch may be needed in input for a joystick set that is
dependent on it.

This was introduced initially via commit 78289b4a ("iio: core: pass
parent device as parameter during allocation"), but was accidentally
removed via commit 6d4ebd56 ("iio: core: wrap IIO device into an
iio_dev_opaque object").

This looks like a rebase gone wrong, and ends up breaking devicetree
bindings of IIO clients.

This change adds back the parent assignment.

This change does the following:
* removes the SPI device table in favor of the OF device table
* adds 'name' && 'chip_id' fields to chip_info
* implements chip ID & silicon revision checking; the device ID for
  AD7124-4 is 0x0, so just checking that value can be useless;
  but at least the silicon revision isn't 0, so a non-zero value can be
  used to check that "a" device is on the SPI bus; it's probably the best
  way to narrow it down to one of the 2 AD7124 chip IDs

Since now we have a notifier block for each DPSW instance probed, we
have to also check that the netdev is indeed connected to the notifier
received. Without this, we end up with the same switchdev callback being
executed multiple times (because it would be received by all notifier
blocks, not just the one intended to).
Also, move the function higher in the source file because it will be
used in later patches from multiple places.

This drivers allows to use the capture mode of the Timer Counter Block
hardware block available in Microchip SoCs through the counter subsystem.

Two functions of the counter are supported for the moment: period
capture and quadrature decoder. The latter is only supported by the
SAMA5 series of SoCs.

For the period capture mode a basic setup has been chosen that will
reset the counter each time the period is actually reached. Of course
the device offers much more possibilities.

For quadrature mode, both channel 0 and 1 must be configured even if we
only capture the position (no revolution/rotation).

The SADC component in JZ47xx SoCs provides support for touchscreen
operations (pen position and pen down pressure) in single-ended and
differential modes.

The touchscreen component of SADC takes a significant time to stabilize
after first receiving the clock and a delay of 50ms has been empirically
proven to be a safe value before data sampling can begin.

Of the known hardware to use this controller, GCW Zero and Anbernic RG-350
utilize the touchscreen mode by having their joystick(s) attached to the
X/Y positive/negative input pins.

JZ4770 and later SoCs introduce a low-level command feature. With it, up
to 32 commands can be programmed, each one corresponding to a sampling
job. It allows to change the low-voltage reference, the high-voltage
reference, have them connected to VCC, GND, or one of the X-/X+ or Y-/Y+
pins.

This patch introduces support for 6 stream-capable channels:
- channel #0 samples X+/GND
- channel #1 samples Y+/GND
- channel #2 samples X-/GND
- channel #3 samples Y-/GND
- channel #4 samples X+/X-
- channel #5 samples Y+/Y-

Being able to sample X-/GND and Y-/GND is useful on some devices, where
one joystick is connected to the X+/Y+ pins, and a second joystick is
connected to the X-/Y- pins.

All the boards which probe this driver have the interrupt provided from
Device Tree, with no need to handle a case where the IRQ was not provided.
