| Common i2c arbitration bus properties. |
| |
| - i2c-arb child node |
| |
| Required properties for the i2c-arb child node: |
| - #address-cells = <1>; |
| - #size-cells = <0>; |
| |
| Optional properties for i2c-arb child node: |
| - Child nodes conforming to i2c bus binding |
| |
| |
| Example : |
| |
| /* |
| An NXP pca9541 I2C bus master selector at address 0x74 |
| with a NXP pca8574 GPIO expander attached. |
| */ |
| |
| arb@74 { |
| compatible = "nxp,pca9541"; |
| reg = <0x74>; |
| |
| i2c-arb { |
| #address-cells = <1>; |
| #size-cells = <0>; |
| |
| gpio@38 { |
| compatible = "nxp,pca8574"; |
| reg = <0x38>; |
| #gpio-cells = <2>; |
| gpio-controller; |
| }; |
| }; |
