Add SDM845 PDC (Power Domain Controller) reset controller binding
Even though this is currently describing only a reset controller I think
this binding better be talking about the "PDC Global" hardware.

Rename this qcom,pdc-global to match the compatible, and hardware name.

+PDC Reset Controller
PDC Global
+======================================
+
+This binding describes a reset-controller found on PDC-Global(Power Domain
+Controller) block for Qualcomm Technologies Inc SDM845 SoCs.
This looks good.
+
+Required properties:
+- compatible:
+	Usage: required
+	Value type: <string>
+	Definition: must be:
+		    "qcom,sdm845-pdc-global"
+
+- reg:
+	Usage: required
+	Value type: <prop-encoded-array>
+	Definition: must specify the base address and size of the register
+	            space.
+
+- #reset-cells:
+	Usage: required
+	Value type: <uint>
+	Definition: must be 1; cell entry represents the reset index.
+
+Example:
+
+pdc_reset: reset-controller@b2e0000 {
This is perfectly fine, in its current form it is a reset-controller.
+	compatible = "qcom,sdm845-pdc-global";
+	reg = <0xb2e0000 0x20000>;
+	#reset-cells = <1>;
+};
+
Apart from this, the binding looks good!

Bjorn
