Qualcomm ADSP Peripheral Image Loader
This document defines the binding for a component that loads and boots firmware
on the Qualcomm ADSP Hexagon core.
- compatible:
Usage: required
Value type: <string>
Definition: must be one of:
"qcom,msm8974-adsp-pil"
"qcom,msm8996-adsp-pil"
"qcom,msm8996-slpi-pil"
- interrupts-extended:
Usage: required
Value type: <prop-encoded-array>
Definition: must list the watchdog, fatal IRQs ready, handover and
stop-ack IRQs
- interrupt-names:
Usage: required
Value type: <stringlist>
Definition: must be "wdog", "fatal", "ready", "handover", "stop-ack"
- clocks:
Usage: required
Value type: <prop-encoded-array>
Definition: reference to the xo clock and optionally aggre2 clock to be
held on behalf of the booting Hexagon core
- clock-names:
Usage: required
Value type: <stringlist>
Definition: must be "xo" and optionally include "aggre2"
- cx-supply:
Usage: required
Value type: <phandle>
Definition: reference to the regulator to be held on behalf of the
booting Hexagon core
- px-supply:
Usage: required
Value type: <phandle>
Definition: reference to the px regulator to be held on behalf of the
booting Hexagon core
- memory-region:
Usage: required
Value type: <phandle>
Definition: reference to the reserved-memory for the ADSP
- qcom,smem-states:
Usage: required
Value type: <phandle>
Definition: reference to the smem state for requesting the ADSP to
shut down
- qcom,smem-state-names:
Usage: required
Value type: <stringlist>
Definition: must be "stop"
= SUBNODES
The adsp node may have an subnode named "smd-edge" that describes the SMD edge,
channels and devices related to the ADSP. See ../soc/qcom/qcom,smd.txt for
details on how to describe the SMD edge.
= EXAMPLE
The following example describes the resources needed to boot control the
ADSP, as it is found on MSM8974 boards.
adsp {
compatible = "qcom,msm8974-adsp-pil";
interrupts-extended = <&intc 0 162 IRQ_TYPE_EDGE_RISING>,
<&adsp_smp2p_in 0 IRQ_TYPE_EDGE_RISING>,
<&adsp_smp2p_in 1 IRQ_TYPE_EDGE_RISING>,
<&adsp_smp2p_in 2 IRQ_TYPE_EDGE_RISING>,
<&adsp_smp2p_in 3 IRQ_TYPE_EDGE_RISING>;
interrupt-names = "wdog",
"fatal",
"ready",
"handover",
"stop-ack";
clocks = <&rpmcc RPM_CXO_CLK>;
clock-names = "xo";
cx-supply = <&pm8841_s2>;
memory-region = <&adsp_region>;
qcom,smem-states = <&adsp_smp2p_out 0>;
qcom,smem-state-names = "stop";
smd-edge {
interrupts = <0 156 IRQ_TYPE_EDGE_RISING>;
qcom,ipc = <&apcs 8 8>;
qcom,smd-edge = <1>;
};
};
The following example describes the resources needed to boot control the
SLPI, as it is found on MSM8996 boards.
slpi {
compatible = "qcom,msm8996-slpi-pil";
interrupts-extended = <&intc 0 390 IRQ_TYPE_EDGE_RISING>,
<&slpi_smp2p_in 0 IRQ_TYPE_EDGE_RISING>,
<&slpi_smp2p_in 1 IRQ_TYPE_EDGE_RISING>,
<&slpi_smp2p_in 2 IRQ_TYPE_EDGE_RISING>,
<&slpi_smp2p_in 3 IRQ_TYPE_EDGE_RISING>;
interrupt-names = "wdog",
"fatal",
"ready",
"handover",
"stop-ack";
clocks = <&rpmcc MSM8996_RPM_SMD_XO_CLK_SRC>,
<&rpmcc MSM8996_RPM_SMD_AGGR2_NOC_CLK>;
clock-names = "xo", "aggre2";
cx-supply = <&pm8994_l26>;
px-supply = <&pm8994_lvs2>;
memory-region = <&slpi_region>;
qcom,smem-states = <&slpi_smp2p_out 0>;
qcom,smem-state-names = "stop";
};
