Describe the PWM block on IPQ6018.

The PWM is in the TCSR area. Make &tcsr "simple-mfd" compatible, and add
&pwm as child of &tcsr.

Add also ipq6018 specific compatible string.

   Add 'ranges' property (Rob)


   Add size cell to 'reg' (Rob)


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

   Add qcom,tcsr-ipq6018 (Rob)

   Drop clock-names (Bjorn)


   Make the PWM node child of TCSR (Rob Herring)

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

v5: Use qcom,pwm-regs for TCSR phandle instead of direct regs

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

Hi Krzysztof,
Referring to, it seems that the TCSR block should
not have any child nodes. Could you pls provide your suggestions on pwm
being added as the child node?
