Qualcomm Hexagon Peripheral Image Loader
This document defines the binding for a component that loads and boots firmware
on the Qualcomm Hexagon core.
- compatible:
Usage: required
Value type: <string>
Definition: must be one of:
"qcom,q6v5-pil",
"qcom,msm8916-mss-pil",
"qcom,msm8974-mss-pil"
"qcom,msm8996-mss-pil"
"qcom,sdm845-mss-pil"
- reg:
Usage: required
Value type: <prop-encoded-array>
Definition: must specify the base address and size of the qdsp6 and
rmb register blocks
- reg-names:
Usage: required
Value type: <stringlist>
Definition: must be "q6dsp" and "rmb"
- 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: <phandle>
Definition: reference to the iface, bus and mem clocks to be held on
behalf of the booting of the Hexagon core
- clock-names:
Usage: required
Value type: <stringlist>
Definition: must be "iface", "bus", "mem"
- resets:
Usage: required
Value type: <phandle>
Definition: reference to the reset-controller for the modem sub-system
- reset-names:
Usage: required
Value type: <stringlist>
Definition: must be "mss_restart"
- cx-supply:
- mss-supply:
- mx-supply:
- pll-supply:
Usage: required
Value type: <phandle>
Definition: reference to the regulators to be held on behalf of the
booting of the Hexagon core
- qcom,smem-states:
Usage: required
Value type: <phandle>
Definition: reference to the smem state for requesting the Hexagon to
shut down
- qcom,smem-state-names:
Usage: required
Value type: <stringlist>
Definition: must be "stop"
- qcom,halt-regs:
Usage: required
Value type: <prop-encoded-array>
Definition: a phandle reference to a syscon representing TCSR followed
by the three offsets within syscon for q6, modem and nc
halt registers.
= SUBNODES:
The Hexagon node must contain two subnodes, named "mba" and "mpss" representing
the memory regions used by the Hexagon firmware. Each sub-node must contain:
- memory-region:
Usage: required
Value type: <phandle>
Definition: reference to the reserved-memory for the region
The Hexagon node may also have an subnode named either "smd-edge" or
"glink-edge" that describes the communication edge, channels and devices
related to the Hexagon. See ../soc/qcom/qcom,smd.txt and
../soc/qcom/qcom,glink.txt for details on how to describe these.
= EXAMPLE
The following example describes the resources needed to boot control the
Hexagon, as it is found on MSM8974 boards.

compatible = "qcom,q6v5-pil";
reg = <0xfc880000 0x100>,
<0xfc820000 0x020>;

<&modem_smp2p_in 0 0>,
<&modem_smp2p_in 1 0>,
<&modem_smp2p_in 2 0>,
<&modem_smp2p_in 3 0>;
interrupt-names = "wdog",
"fatal",
"ready",
"handover",
"stop-ack";

};
mpss {
memory-region = <&mpss_region>;
};
};
