There is no real advantage in having these protections and
for parts that do not have an explicit ACPI ID, it prevents the
use of PRP0001. I'm trying to clear this out of IIO in general
to avoid copying in new drivers.
Include mod_devicetable.h as we are using of_device_id in here so
including that header is best practice.

This driver cannot be instantiated from ACPI due to it's use of
syscon_regmap_lookup_by_phandle() but in the interests of clearing
this anti pattern out of IIO, let us switch to an explicit
check in Kconfig and remove the protections on the of_match_table
The switch of header is because we only use of_device_id
in here and that is defined in mod_devicetable.h not of.h.

Support for AMS AS73211 JENCOLOR(R) Digital XYZ Sensor.
This driver has no built-in trigger. In order for making triggered
measurements, an external (software) trigger driver like
iio-trig-hrtimer or iio-trig-sysfs is required.
The sensor supports single and continuous measurement modes. The latter
is not used by design as this would require tight timing synchronization
between hardware and driver without much benefit.

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

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.
