[PATCH] dt-bindings: iio: gyroscope: bosch,bmg160: add spi-max-frequency binding

[Marco Felsch]

Make use of the common spi-peripheral-props.yaml to pull in the common
spi device properties and limit the spi-max-frequency to 10 MHz as this
is the max. frequency if VDDIO >= 1.62V.

The example uses i2c, so I would expect to see in commit msg explanation
which devices are SPI devices.

Also:
A nit, subject: drop second/last, redundant "binding". The "dt-bindings"
prefix is already stating that these are bindings.

Best regards,
Krzysztof

All listed devices can either operate in I2C or in SPI mode.

Will rephrase it if you want me to update the commit message.

Such information in commit msg would be enough.

Added the note whilst applying.

Applied to the togreg branch of iio.git and pushed out (briefly given
timing) as testing for 0-day to take a first look.

Thanks,
