Subject: [PATCH 3/3] arm64: dts: ipq6018: add pwm node
Date: Mon,  7 Feb 2022 11:30:45 +0200	[thread overview]
Message-ID: <989c681a730f38b1a5f09dbb31552d9b974e400e.1644226245.git.baruch@tkos.co.il> (raw)
In-Reply-To: <17dd231f496d09ed8502bdd505eaa77bb6637e4b.1644226245.git.baruch@tkos.co.il>

From: Baruch Siach <baruch.siach@siklu.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.

Signed-off-by: Baruch Siach <baruch.siach@siklu.com>

v9:

  Add 'ranges' property (Rob)

v8:

  Add size cell to 'reg' (Rob)

v7:

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

  Add qcom,tcsr-ipq6018 (Rob)

  Drop clock-names (Bjorn)

v6:

  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)
