70de3868eb dt-bindings: iio: dac: ad5686: extend device support
Add compatible entries for AD5313R, AD5317R, AD5674, AD5679, AD5687,
AD5687R, AD5689, AD5689R. These devices have unique combination of channel
count, bit resolution and supported command set, so that fallback
compatibles are not used. Also, a small copy-and-paste error is fixed to
the title field.

692d2294c2 dt-bindings: iio: dac: ad5686: rework on power supplies
Add supplies for VDD, VLOGIC and VREF input voltage pins. The vcc-supply
property is deprecated, once it does not really exist as none of the
devices describe any power input with that name. VCC is also misleading as
it sounds like the input power supply, but it is being used as an external
voltage reference, which should be called VREF. Certain devices require
vref-supply to be available once an internal reference voltage is absent.
For correct operation vdd and vlogic supplies are required.

Add compatible strings for the LTC2654 quad-channel DAC family.

format as the LTC2632/2634/2636 family.

The 16-bit variants (LTC2654-L16 and LTC2654-H16) require new
compatible strings, as no existing compatibles support 16-bit
resolution.

The 12-bit variants (LTC2654-L12 and LTC2654-H12) are register-
compatible with LTC2634-L12 and LTC2634-H12 respectively, and can
use them as fallback compatibles.

043e4e514c dt-bindings: iio: dac: adi-axi-dac: add ad3552r axi variant
Add a new compatible and related bindigns for the fpga-based
"ad3552r" AXI IP core, a variant of the generic AXI DAC IP.

The AXI "ad3552r" IP is a very similar HDL (fpga) variant of the
generic AXI "DAC" IP, intended to control ad3552r and similar chips,
mainly to reach high speed transfer rates using a QSPI DDR
(dobule-data-rate) interface.

The ad3552r device is defined as a child of the AXI DAC, that in
this case is acting as an SPI controller.

Note, #io-backend is present because it is possible (in theory anyway)
to use a separate controller for the control path than that used
for the datapath.

For this case, the binding is modified to include some additional

0fbce5d171 dt-bindings: iio: dac: fix ad3552r gain parameter names
The adi,gain-scaling-p/n values are an inverted log2,
so initial naming was set correctly, but the driver uses just
adi,gain-scaling-p/n, and if fdt is created accordingly with
the fdt bindings documentation, driver fails the probe.

Observing that:
- the Linux driver is the only consumer,
- there are no upstreamed dts nodes related to ad3552r,

the fix to the documentation side is preferred and less-risk.

Description of this property is added to all peripheral binding files of
the peripheral under the STM32 firewall controller. It allows an accurate
representation of the hardware, where various peripherals are connected
to a firewall bus. The firewall can then check the peripheral accesses
before allowing its device to probe.
