From: Angelo Dureghello <adureghello@baylibre.com>
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.

Defined in spi-controller.yaml, so you don't need them here.

Maybe an issue in the tooling? pinctrl properties are allowed on any node and so the tools add the property pattern to the schemas. If that wasn't the case, then it would be the same error, but just list the channel regex. Perhaps not all that useful to list regex's that don't match. In any case, the error is simply that io-backends is not defined as a property. Rob
