1 Qualcomm Hexagon Peripheral Image Loader
3 This document defines the binding for a component that loads and boots firmware
4 on the Qualcomm Hexagon core.
9 Definition: must be one of:
11 "qcom,msm8916-mss-pil",
12 "qcom,msm8974-mss-pil"
16 Value type: <prop-encoded-array>
17 Definition: must specify the base address and size of the qdsp6 and
22 Value type: <stringlist>
23 Definition: must be "q6dsp" and "rmb"
25 - interrupts-extended:
27 Value type: <prop-encoded-array>
28 Definition: must list the watchdog, fatal IRQs ready, handover and
33 Value type: <stringlist>
34 Definition: must be "wdog", "fatal", "ready", "handover", "stop-ack"
39 Definition: reference to the iface, bus and mem clocks to be held on
40 behalf of the booting of the Hexagon core
44 Value type: <stringlist>
45 Definition: must be "iface", "bus", "mem"
50 Definition: reference to the reset-controller for the modem sub-system
54 Value type: <stringlist>
55 Definition: must be "mss_restart"
63 Definition: reference to the regulators to be held on behalf of the
64 booting of the Hexagon core
69 Definition: reference to the smem state for requesting the Hexagon to
72 - qcom,smem-state-names:
74 Value type: <stringlist>
75 Definition: must be "stop"
79 Value type: <prop-encoded-array>
80 Definition: a phandle reference to a syscon representing TCSR followed
81 by the three offsets within syscon for q6, modem and nc
85 The Hexagon node must contain two subnodes, named "mba" and "mpss" representing
86 the memory regions used by the Hexagon firmware. Each sub-node must contain:
91 Definition: reference to the reserved-memory for the region
93 The Hexagon node may also have an subnode named either "smd-edge" or
94 "glink-edge" that describes the communication edge, channels and devices
95 related to the Hexagon. See ../soc/qcom/qcom,smd.txt and
96 ../soc/qcom/qcom,glink.txt for details on how to describe these.
99 The following example describes the resources needed to boot control the
100 Hexagon, as it is found on MSM8974 boards.
