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>;
};
