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>; | ||
