[PATCH v5 1/3] i2c: cadence: Document device tree bindings
Add device tree binding documentation for the Cadence I2C controller.
Signed-off-by: Soren Brinkmann
---
Changes in v5:
- Document all properties
- list clock-names as optional property (driver doesn't use it, though)
- use lower case hex digits in 'reg' property
- reword description of 'clocks' property
- remove implementation specific notes regarding default speed
- use #defines for interrupt specifier
Changes in v4:
- moved adding DT docs into this dedicated patch
Changes in v3: None
Changes in v2: None

+Binding for the Cadence I2C controller
+
+Required properties:
+ - reg: Physical base address and size of the controller's register area.
+ - compatible: Compatibility string. Must be 'cdns,i2c-r1p10'.
+ - clocks: Input clock specifier. Refer to common clock bindings.
+ - interrupts: Interrupt specifier. Refer to interrupt bindings.
+ - #address-cells: Should be 1.
+ - #size-cells: Should be 0.
+
+Optional properties:
+ - clock-frequency: Desired operating frequency, in Hz, of the bus.
+ - clock-names: Input clock name, should be 'pclk'.
+
+Example:
+ i2c@e0004000 {
+ compatible = "cdns,i2c-r1p10";
+ clocks = < 38>;
+ interrupts = ;
+ reg = <0xe0004000 0x1000>;
+ clock-frequency = <40>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ };
