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

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

[David Heidelberg]

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.

-QCOM Top Control and Status Register
-
-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
-		"qcom,tcsr-msm8960", "syscon" for MSM8960
-		"qcom,tcsr-msm8974", "syscon" for MSM8974
-		"qcom,tcsr-apq8084", "syscon" for APQ8084
-		"qcom,tcsr-msm8916", "syscon" for MSM8916
-- reg: Address range for TCSR registers
-
-Example:
-	tcsr: syscon@1a400000 {
-		compatible = "qcom,tcsr-msm8960", "syscon";
-		reg = <0x1a400000 0x100>;

There is about to be. See:

[David Heidelberg]

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

What you think Rob?
