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";
|
||||
};
