v12:

Picked up the R-b tag

v11:

No change

v10:

No change

v9:

Add 'ranges' property to example (Rob)

Drop label in example (Rob)

v8:

Add size cell to 'reg' (Rob)

v7:

Use 'reg' instead of 'offset' (Rob)

Drop 'clock-names' and 'assigned-clock*' (Bjorn)

Use single cell address/size in example node (Bjorn)

Move '#pwm-cells' lower in example node (Bjorn)

List 'reg' as required

v6:

Device node is child of TCSR; remove phandle (Rob Herring)

Add assigned-clocks/assigned-clock-rates (Uwe Kleine-König)

v5: Use qcom,pwm-regs for phandle instead of direct regs (Bjorn
Andersson, Kathiravan T)

v4: Update the binding example node as well (Rob Herring's bot)

v3: s/qcom,pwm-ipq6018/qcom,ipq6018-pwm/ (Rob Herring)

v2: Make #pwm-cells const (Rob Herring)

Filename matching compatible, so qcom,ipq6018-pwm.yaml

compatible is always the first property.

And this order must be the same as in properties.

Drop this node, not related. The parent binding could have full example,
on the other hand. Additionally, I have doubts that you really tested
the parent binding.

We would have other ipq compatibles (ipq9574 & ipq5332) being added to
the binding in the upcoming series.
So, shall we rename the binding to qcom,ipq-pwm.yaml
