Subject: [PATCH v2 1/3] dt-bindings: iio: frequency: add adf4377 doc
Add device tree bindings for the ADF4377 driver.
Signed-off-by: Antoniu Miclaus <antoniu.miclaus@...log.com>
---
changes in v2:
- use GPIO with uppercase in the property description
- add `adi,muxout-select` property
- add maintainer in this patch
- add allOf with reference to spi-peripheral-props.yaml
- use unevaluatedProperties

+ The ADF4377 is a high performance, ultralow jitter, dual output integer-N
+ phased locked loop (PLL) with integrated voltage controlled oscillator (VCO)
+ ideally suited for data converter and mixed signal front end (MxFE) clock
+ applications.
