Subject: [PATCH V14 3/4] dt-bindings: mfd: qcom,tcsr: Add simple-mfd support for IPQ6018
Update the binding to include pwm as the child node to TCSR block and
add simple-mfd support for IPQ6018.
Signed-off-by: Devi Priya <quic_devipriy@...cinc.com>
---
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
