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"
include: ["nordic,nrf-twi-common.yaml", "memory-region.yaml"]
