Subject: [PATCH V12 3/3] arm64: dts: ipq6018: add pwm node
Date: Mon, 25 Sep 2023 12:29:15 +0530 [thread overview]
Message-ID: <20230925065915.3467964-4-quic_devipriy@quicinc.com> (raw)
In-Reply-To: <20230925065915.3467964-1-quic_devipriy@quicinc.com>
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.
