Qualcomm AOSS Reset Controller
======================================

This binding describes a reset-controller found on AOSS-CC (always on subsystem)
for Qualcomm SDM845 SoCs.

Required properties:
- compatible:
	Usage: required
	Value type: <string>
	Definition: must be:
		    "qcom,sdm845-aoss-cc"

- 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:

aoss_reset: reset-controller@c2a0000 {
	compatible = "qcom,sdm845-aoss-cc";
	reg = <0xc2a0000 0x31000>;
	#reset-cells = <1>;
};

Specifying reset lines connected to IP modules
==============================================

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 list of all valid reset indicies see
<dt-bindings/reset/qcom,sdm845-aoss.h>

Example:

modem-pil@4080000 {
	...

	resets = <&aoss_reset AOSS_CC_MSS_RESTART>;
	reset-names = "mss_restart";

	...
};
