Binding for the Qualcomm APCS global block ========================================== 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" "qcom,msm8998-apcs-hmss-global" "qcom,qcs404-apcs-apps-global" "qcom,sc7180-apss-shared" "qcom,sdm845-apss-shared" "qcom,sm8150-apss-shared" "qcom,ipq8074-apcs-apps-global" - reg: Usage: required Value type: <prop-encoded-array> Definition: must specify the base address and size of the global block - clocks: Usage: required if #clocks-cells property is present Value type: <phandle> Definition: phandle to the input PLL, which feeds the APCS mux/divider - #mbox-cells: Usage: required Value type: <u32> Definition: as described in mailbox.txt, must be 1 - #clock-cells: Usage: optional Value type: <u32> Definition: as described in clock.txt, must be 0 = 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"; }; Below is another example of the APCS binding on MSM8916 platforms: apcs: mailbox@b011000 { compatible = "qcom,msm8916-apcs-kpss-global"; reg = <0xb011000 0x1000>; #mbox-cells = <1>; clocks = <&a53pll>; #clock-cells = <0>; }; |
