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)
