1 | Binding for the Cadence I2C controller |
2 | ||
3 | Required properties: | |
4 | - reg: Physical base address and size of the controller's register area. | |
5 | - compatible: Compatibility string. Must be 'cdns,i2c-r1p10'. | |
6 | - clocks: Input clock specifier. Refer to common clock bindings. | |
7 | - interrupts: Interrupt specifier. Refer to interrupt bindings. | |
8 | - #address-cells: Should be 1. | |
9 | - #size-cells: Should be 0. | |
10 | ||
11 | Optional properties: | |
12 | - clock-frequency: Desired operating frequency, in Hz, of the bus. | |
13 | - clock-names: Input clock name, should be 'pclk'. | |
14 | ||
15 | Example: | |
16 | i2c@e0004000 { | |
17 | compatible = "cdns,i2c-r1p10"; | |
18 | clocks = <&clkc 38>; | |
19 | interrupts = <GIC_SPI 25 IRQ_TYPE_LEVEL_HIGH>; | |
20 | reg = <0xe0004000 0x1000>; | |
21 | clock-frequency = <400000>; | |
22 | #address-cells = <1>; | |
23 | #size-cells = <0>; | |
24 | }; |
