Subject: [PATCH 2/5] dt-binding:Rename the mbigen binding file name
From: Ma Jun <majun258@...wei.com>
Because added the mbigen-v1 compatible string, the origin name is
not suitable any more. So,I remove the version number from file name.
Signed-off-by: Ma Jun <majun258@...wei.com>

-Hisilicon mbigen device tree bindings.
-=======================================
-
-Mbigen means: message based interrupt generator.
-
-MBI is kind of msi interrupt only used on Non-PCI devices.
-
-To reduce the wired interrupt number connected to GIC,
-Hisilicon designed mbigen to collect and generate interrupt.
-
-
-Non-pci devices can connect to mbigen and generate the
-interrupt by writing ITS register.
-
-The mbigen chip and devices connect to mbigen have the following properties:
-
-Mbigen main node required properties:
--------------------------------------------
-- compatible: Should be "hisilicon,mbigen-v2" or "hisilicon,mbigen-v1"
-
-- reg: Specifies the base physical address and size of the Mbigen
- registers.
-
-- interrupt controller: Identifies the node as an interrupt controller
-
-- msi-parent: Specifies the MSI controller this mbigen use.
- For more detail information,please refer to the generic msi-parent binding in
- Documentation/devicetree/bindings/interrupt-controller/msi.txt.
-
-- num-pins: the total number of pins implemented in this Mbigen
- instance.
-
-- #interrupt-cells : Specifies the number of cells needed to encode an
- interrupt source. The value must be 2.
-
- The 1st cell is hardware pin number of the interrupt.This number is local to
- each mbigen chip and in the range from 0 to the maximum interrupts number
- of the mbigen.
-
- The 2nd cell is the interrupt trigger type.
- The value of this cell should be:
- 1: rising edge triggered
- or
- 4: high level triggered
-
-Examples:
-
- mbigen_device_gmac:intc {
- compatible = "hisilicon,mbigen-v2";
- reg = <0x0 0xc0080000 0x0 0x10000>;
- interrupt-controller;
- msi-parent = <&its_dsa 0x40b1c>;
- num-pins = <9>;
- #interrupt-cells = <2>;
- };
-
-Devices connect to mbigen required properties:
-----------------------------------------------------
--interrupt-parent: Specifies the mbigen device node which device connected.
-
--interrupts:Specifies the interrupt source.
- For the specific information of each cell in this property,please refer to
- the "interrupt-cells" description mentioned above.
-
-Examples:
- gmac0: ethernet@...80000 {
- #address-cells = <1>;
- #size-cells = <0>;
- reg = <0 0xc2080000 0 0x20000>,
- <0 0xc0000000 0 0x1000>;
- interrupt-parent = <&mbigen_device_gmac>;
- interrupts = <656 1>,
- <657 1>;
- };
