Hi Yoko-S,

What specifically is the customer looking for in terms of software? What exactly is a DTS request? The TCA6408A is an I2C IO expander with minimal coding to get the device working, and software related instructions for proper implementation of the device are found in the datasheet. We do not have example code for this device that we give out. Normally we can test all functionality with a simple arduino script or using an I2C compatible driver such as the Aardvark from Total Phase.

Regards,

Tyler

DTS is stand for Device tree source. it seems like ".dts" file is needed for evaluating TCA6408A in this case.

The TCA6408A is handled by the gpio-pca953x driver; its device tree compatible ID would be "ti,tca6408".

The device tree describes how the device is wired up to the master and to other devices, so it is not possible to provide an example that would work in every customer's random application. See the examples in the documentation for how to write your own.
