92c7ae3486 dt-bindings: iio: accel: bosch,bma220 set irq type in example block
Set the interrupt type to rising edge within the example block in order
to match the new driver.

The entry that got replaced was not in use by the original driver.

b8719569a0 dt-bindings: iio: accel: bosch,bma220 setup SPI clock mode
Assert CPOL for a high-idle clock signal and CPHA for sampling on the
trailing (rising) edge.

Quoting from the datasheet:

 "During the transitions on CSB, SCK must be high. SDI and SDO are driven
 at the falling edge of SCK and should be captured at the rising edge of
 SCK."

The sensor does not function with the default SPI clock mode.

46908557a5 dt-bindings: iio: correct node names in examples
Do not use underscores and unneeded suffixes (e.g. i2c0) in node name in
examples.

5f72930016 dt-bindings: iio: accel: use spi-peripheral-props.yaml
Instead of listing directly properties typical for SPI peripherals,
reference the spi-peripheral-props.yaml schema.  This allows using all
properties typical for SPI-connected devices, even these which device
bindings author did not tried yet.

Remove the spi-* properties which now come via spi-peripheral-props.yaml
schema, except for the cases when device schema adds some constraints
like maximum frequency.

While changing additionalProperties->unevaluatedProperties, put it in
typical place, just before example DTS.

7dbd479425 dt-bindings:iio:accel:bosch,bma220 device tree binding documentation
Linux driver currently relies on the driver.name to match to the
compatible, but that doesn't mean it isn't a good idea to document it.

Only real complexity is the 3 separate power supplies.
