From b4a32d218d424b81a58fbd419e1114b1c1f76168 Mon Sep 17 00:00:00 2001
From: Devi Priya <quic_devipriy@quicinc.com>

Subject: [PATCH] pwm: driver for qualcomm ipq6018 pwm block
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.
