Subject: [PATCH v7 1/3] dt-bindings: mailbox: Introduce Hi3660 controller binding
Date: Fri, 16 Mar 2018 00:07:36 +0800 [thread overview]
Message-ID: <1521130058-24796-2-git-send-email-leo.yan@linaro.org> (raw)
In-Reply-To: <1521130058-24796-1-git-send-email-leo.yan@linaro.org>
Introduce a binding for the Hi3660 mailbox controller, the mailbox is
used within application processor (AP), communication processor (CP),
HIFI and MCU, etc.

+Hisilicon Hi3660 Mailbox Controller
+
+Hisilicon Hi3660 mailbox controller supports up to 32 channels. Messages
+are passed between processors, including application & communication
+processors, MCU, HIFI, etc. Each channel is unidirectional and accessed
+by using MMIO registers; it supports maximum to 8 words message.
+
+Controller
+----------
+
+Required properties:
+- compatible: : Shall be "hisilicon,hi3660-mbox"
+- reg: : Offset and length of the device's register set
+- #mbox-cells: : Must be 3
+ <&phandle channel dst_irq ack_irq>
+ phandle : Label name of controller
+ channel : Channel number
+ dst_irq : Remote interrupt vector
+ ack_irq : Local interrupt vector
+
+- interrupts: : Contains the two IRQ lines for mailbox.
+
+Example:
+
+mailbox: mailbox@e896b000 {
+ compatible = "hisilicon,hi3660-mbox";
+ reg = <0x0 0xe896b000 0x0 0x1000>;
+ interrupts = <0x0 0xc0 0x4>,
+ <0x0 0xc1 0x4>;
+ #mbox-cells = <3>;
+};
+
+Client
+------
+
+Required properties:
+- compatible : See the client docs
+- 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:
+
+stub_clock: stub_clock@e896b500 {
+ compatible = "hisilicon,hi3660-stub-clk";
+ reg = <0x0 0xe896b500 0x0 0x0100>;

+ mboxes = <&mailbox 13 3 0>;
