ST Microelectronics Mailbox Driver
Each ST Mailbox IP currently consists of 4 instances of 32 channels. Messages
are passed between Application and Remote processors using shared memory.
Controller
----------
Required properties:
- compatible : Should be "st,stih407-mailbox"
- reg : Offset and length of the device's register set
- mbox-name : Name of the mailbox
- #mbox-cells: : Must be 2
<&phandle instance channel direction>
phandle : Label name of controller
instance : Instance number
channel : Channel number
Optional properties
- interrupts : Contains the IRQ line for a Rx mailbox
Example:
mailbox0: mailbox@0 {
compatible = "st,stih407-mailbox";
reg = <0x08f00000 0x1000>;
interrupts = <GIC_SPI 1 IRQ_TYPE_NONE>;
#mbox-cells = <2>;
mbox-name = "a9";
};
Client
------
Required properties:
- compatible : Many (See the client docs)
- reg : Shared (between Application and Remote) memory address
- mboxes : Standard property to specify a Mailbox (See ./mailbox.txt)
Cells must match 'mbox-cells' (See Controller docs above)
Optional properties
- mbox-names : Name given to channels seen in the 'mboxes' property.
Example:
mailbox_test {
compatible = "mailbox-test";
reg = <0x[shared_memory_address], [shared_memory_size]>;
mboxes = <&mailbox2 0 1>, <&mailbox0 2 1>;
mbox-names = "tx", "rx";
};

Qualcomm GLINK edge binding
This binding describes a Qualcomm GLINK edge, a fifo based mechanism for
communication between subsystem-pairs on various Qualcomm platforms. Two types
of edges can be described by the binding; the GLINK RPM edge and a SMEM based
edge.
- compatible:
Usage: required for glink-rpm
Value type: <stringlist>
Definition: must be "qcom,glink-rpm"
- label:
Usage: optional
Value type: <string>
Definition: should specify the subsystem name this edge corresponds to.
- interrupts:
Usage: required
Value type: <prop-encoded-array>
Definition: should specify the IRQ used by the remote processor to
signal this processor about communication related events
- qcom,remote-pid:
Usage: required for glink-smem
Value type: <u32>
Definition: specifies the identifier of the remote endpoint of this edge
- qcom,rpm-msg-ram:
Usage: required for glink-rpm
Value type: <prop-encoded-array>
Definition: handle to RPM message memory resource
- mboxes:
Usage: required
Value type: <prop-encoded-array>
Definition: reference to the "rpm_hlos" mailbox in APCS, as described
in mailbox/mailbox.txt
= GLINK DEVICES
Each subnode of the GLINK node represent function tied to a virtual
communication channel. The name of the nodes are not important. The properties
of these nodes are defined by the individual bindings for the specific function
- but must contain the following property:
- qcom,glink-channels:
Usage: required
Value type: <stringlist>
Definition: a list of channels tied to this function, used for matching
the function to a set of virtual channels
- qcom,intents:
Usage: optional
Value type: <prop-encoded-array>
Definition: a list of size,amount pairs describing what intents should
be preallocated for this virtual channel. This can be used
to tweak the default intents available for the channel to
meet expectations of the remote.
= EXAMPLE
The following example represents the GLINK RPM node on a MSM8996 device, with
the function for the "rpm_request" channel defined, which is used for
regulators and root clocks.
apcs_glb: mailbox@9820000 {
compatible = "qcom,msm8996-apcs-hmss-global";
reg = <0x9820000 0x1000>;

};
rpm_msg_ram: memory@68000 {
compatible = "qcom,rpm-msg-ram";
reg = <0x68000 0x6000>;
};
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>;
rpm-requests {
compatible = "qcom,rpm-msm8996";
qcom,glink-channels = "rpm_requests";
qcom,intents = <0x400 5
0x800 1>;
