2==========================================
3
4This binding describes the APCS "global" block found in various Qualcomm
5platforms.
6
7- compatible:
8	Usage: required
9	Value type: <string>
10	Definition: must be one of:
11		    "qcom,msm8916-apcs-kpss-global",
12		    "qcom,msm8996-apcs-hmss-global"
13		    "qcom,msm8998-apcs-hmss-global"

40= EXAMPLE
41The following example describes the APCS HMSS found in MSM8996 and part of the
42GLINK RPM referencing the "rpm_hlos" doorbell therein.
43
44	apcs_glb: mailbox@9820000 {
45		compatible = "qcom,msm8996-apcs-hmss-global";
46		reg = <0x9820000 0x1000>;
47
48		#mbox-cells = <1>;
49	};
50
51	rpm-glink {
52		compatible = "qcom,glink-rpm";
53
54		interrupts = <GIC_SPI 168 IRQ_TYPE_EDGE_RISING>;
55
56		qcom,rpm-msg-ram = <&rpm_msg_ram>;
57
58		mboxes = <&apcs_glb 0>;
59		mbox-names = "rpm_hlos";
60	};
61
62Below is another example of the APCS binding on MSM8916 platforms:
63
64	apcs: mailbox@b011000 {
65		compatible = "qcom,msm8916-apcs-kpss-global";
66		reg = <0xb011000 0x1000>;
67		#mbox-cells = <1>;
68		clocks = <&a53pll>;
69		#clock-cells = <0>;
70	};
