Subject: [PATCH] dt-bindings: mfd: syscon: Add Qualcomm TCSR registers

Qualcomm devices have a set of registers that provide various control and status
functions for their peripherals.

Modification:
- dropped "qcom,tcsr-ipq6018", "syscon", "simple-mfd", since it's not
used anywhere.

-Qualcomm devices have a set of registers that provide various control and status
-functions for their peripherals. This node is intended to allow access to these
-registers via syscon.
-
-Required properties:
-- compatible: Should contain:
- "qcom,tcsr-ipq6018", "syscon", "simple-mfd" for IPQ6018
- "qcom,tcsr-ipq8064", "syscon" for IPQ8064
- "qcom,tcsr-apq8064", "syscon" for APQ8064
- "qcom,tcsr-msm8660", "syscon" for MSM8660

Should I go path specifying MFD or though I could just add minItems: 2
and maxItems: 4 to the list?

What you think Rob?
