v14:
Picked up the R-b tag
v13:
Updated the file name to match the compatible
Sorted the properties and updated the order in the required field
Dropped the syscon node from examples
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)
