-Amlogic Meson MHU Mailbox Driver
-================================
-
-The Amlogic's Meson SoCs Message-Handling-Unit (MHU) is a mailbox controller
-that has 3 independent channels/links to communicate with remote processor(s).
-MHU links are hardwired on a platform. A link raises interrupt for any
-received data. However, there is no specified way of knowing if the sent
-data has been read by the remote. This driver assumes the sender polls
-STAT register and the remote clears it after having read the data.
-
-Mailbox Device Node:
-====================
-
-Required properties:
---------------------
-- compatible: Shall be "amlogic,meson-gxbb-mhu"
-- reg: Contains the mailbox register address range (base
- address and length)
-- #mbox-cells Shall be 1 - the index of the channel needed.
-- interrupts: Contains the interrupt information corresponding to
- each of the 2 links of MHU.
-
-Example:
---------
-
- mailbox: mailbox@c883c404 {
- #mbox-cells = <1>;
- compatible = "amlogic,meson-gxbb-mhu";
- reg = <0 0xc883c404 0 0x4c>;
- interrupts = <0 208 IRQ_TYPE_EDGE_RISING>,
- <0 209 IRQ_TYPE_EDGE_RISING>,
- <0 210 IRQ_TYPE_EDGE_RISING>;
- #mbox-cells = <1>;
- };
