This patch adds bindings for Qualcomm soundwire controller.
Qualcomm SoundWire Master controller is present in most Qualcomm SoCs either integrated as part of WCD audio codecs via slimbus or as part of SOC I/O.

So I was expecting to see bus support patches for OF first. I think you have missed those changes. Please do include those in v2 with bindings and OF support for bus.

On these I think we should have specified dpn properties as specified in DisCo, but then looking at spec we do not define that for master, but bus seems to have it.
Pierre do you why master does not have dpn properties in DisCo?
+- qcom,ports-offset1: Must be frame offset1 of each data port.

These are software so do not belong here
