PDC Global

======================================

This binding describes a reset-controller found on PDC-Global (Power Domain

Controller) block for Qualcomm Technologies Inc SDM845 SoCs.

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 {

	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";

	...

};
