This binding describes the APCS "global" block found in various Qualcomm

platforms.



- compatible:

	Usage: required

	Value type: <string>

	Definition: must be one of:

		    "qcom,msm8916-apcs-kpss-global",

		    "qcom,msm8996-apcs-hmss-global"



- reg:

	Usage: required

	Value type: <prop-encoded-array>

	Definition: must specify the base address and size of the global block



- #mbox-cells:

	Usage: required

= EXAMPLE

The following example describes the APCS HMSS found in MSM8996 and part of the

GLINK RPM referencing the "rpm_hlos" doorbell therein.



	apcs_glb: mailbox@9820000 {

		compatible = "qcom,msm8996-apcs-hmss-global";

		reg = <0x9820000 0x1000>;



		#mbox-cells = <1>;

	};



	rpm-glink {

		compatible = "qcom,glink-rpm";



		interrupts = <GIC_SPI 168 IRQ_TYPE_EDGE_RISING>;



		qcom,rpm-msg-ram = <&rpm_msg_ram>;



		mboxes = <&apcs_glb 0>;

		mbox-names = "rpm_hlos";

	};
