| Nordic nRF family TWIS (TWI slave with EasyDMA). |
| |
| Note: for Zephyr users, the I2C slave API is not available for |
| these devices. See this issue for more details and a HAL-based |
| workaround: |

| https://github.com/zephyrproject-rtos/zephyr/issues/21445 |
| |
| This binding can be used for nodes which can represent TWIS |
| peripherals. A single SoC peripheral ID is often associated with |
| multiple I2C peripherals, like a TWIM and a TWIS. You can choose |
| TWIS by setting the node's "compatible" to "nordic,nrf-twis" |
| and its "status" to "okay", e.g. using an overlay file like this: |
| |
| /* This is for TWIS0 -- change to "i2c1" for TWIS1, etc. */ |
| &i2c0 { |
| compatible = "nordic,nrf-twis"; |
| status = "okay"; |
| /* other property settings can go here */ |
| }; |
| |
| This works on any supported SoC, for all TWIS instances. |
| |
| compatible: "nordic,nrf-twis" |
