Subject: [PATCH V15 3/4] dt-bindings: mfd: qcom,tcsr: Add simple-mfd support for IPQ6018
Date: Thu, 5 Oct 2023 21:35:49 +0530	[thread overview]
Message-ID: <20231005160550.2423075-4-quic_devipriy@quicinc.com> (raw)
In-Reply-To: <20231005160550.2423075-1-quic_devipriy@quicinc.com>

Update the binding to include pwm as the child node to TCSR block and
add simple-mfd support for IPQ6018.

Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
Signed-off-by: Devi Priya <quic_devipriy@quicinc.com>
---
v15:

 Picked up the R-b tag

v14:

Addressed comments suggested by krzysztof

 Added type: object to patternProperties and added the complete path to
 pwm.yaml in the reference

 Disallow pwm for targets other than ipq6018

 Moved ranges property just after reg in the examples

v13:

 Added simple-mfd support for IPQ6018 based devices

 Added support to include pwm as the child node to TCSR

 Included syscon node found on IPQ6018 to the examples
