		QTI BCM-Voter interconnect driver binding
		-----------------------------------------------------------

		The Bus Clock Manager (BCM) is a dedicated hardware accelerator
		that manages shared system resources by aggregating requests
		from multiple Resource State Coordinators (RSC). Interconnect
		providers are able to vote for aggregated thresholds values from
		consumers by communicating through their respective RSCs.

		Required properties :
		- compatible : shall contain only one of the following:
		"qcom,sdm845-bcm-voter",
		"qcom,bcm-voter",

		Examples:

		apps_rsc: interconnect@179c0000 {
		compatible = "qcom,rpmh-rsc";

		apps_bcm_voter: bcm_voter {
		compatible = "qcom,sdm845-bcm-voter";

		SDM845 interconnect providers support system bandwidth requirements through
