maintainerPATCH v2 1/1 dt-bindings:iio:dac:ad5755: txt to yaml format conversion.
From: Jonathan Cameron <[email protected]>
Straight forward conversion. Only fiddly bit is the XOR of spi-cpol and spi-cpha.
---
This has been in a few different series, so version numbering is a bit scrambled. Let's just call it v2.
V2:
* Drop unnecessary refs where units in naming
* Drop unnecessary brackets in child node naming

The applied message for this one seems to be missing. Anyhow for anyone curious, applied some time back.
Thanks,
