	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:

	Definition: must be 1; cell entry represents the reset index.

Example:

pdc_reset: reset-controller@b2e0000 {
	compatible = "qcom,sdm845-pdc-global";
	reg = <0xb2e0000 0x20000>;
	#reset-cells = <1>;
};

PDC reset clients
======================================

Device nodes that need access to reset lines should
specify them as a reset phandle in their corresponding node as
specified in reset.txt.

For a list of all valid reset indices see
<dt-bindings/reset/qcom,sdm845-pdc.h>

Example:

modem-pil@4080000 {
	...

	resets = <&pdc_reset PDC_MODEM_SYNC_RESET>;
	reset-names = "pdc_reset";

	...
};
