Subject: [PATCH v8 1/5] irqchip/aspeed-i2c-ic: binding docs for Aspeed I2C Interrupt Controller
Added device tree binding documentation for Aspeed I2C Interrupt
Controller.
Signed-off-by: Brendan Higgins <brendanhiggins@...gle.com>
---
Added in v6:
- Pulled "aspeed_i2c_controller" out into a interrupt controller since that is
what it actually does.
Changes for v7:
- None
Changes for v8:
- None

+Device tree configuration for the I2C Interrupt Controller on the AST24XX and
+AST25XX SoCs.
+
+Required Properties:
+- #address-cells : should be 1
+- #size-cells : should be 1
+- #interrupt-cells : should be 1
+- compatible : should be "aspeed,ast2400-i2c-ic"
+ or "aspeed,ast2500-i2c-ic"
+- reg : address start and range of controller
+- interrupts : interrupt number
+- interrupt-controller : denotes that the controller receives and fires
+ new interrupts for child busses
+
+Example:
+
+i2c_ic: interrupt-controller@0 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ #interrupt-cells = <1>;
+ compatible = "aspeed,ast2400-i2c-ic";
+ reg = <0x0 0x40>;
+ interrupts = <12>;
+ interrupt-controller;
+};
