Hi Heiner, > I didn't find a single dts(i) with a 10bit i2c device. Because you said In all those years, I didn't even find a device supporting 10 bit addresses. And I really looked especially for them. Some controllers offer 10-bit support in target mode, but that's all I found. Also, there is only one user of I2C_CLIENT_TEN, and this is only a hack to allow instantiating the device at address 0x00. No actual 10-bit usage involved. I will remove this as a first step, because this hack is terrible anyhow. > that you're tempted to remove 10 bit support: Could the device tree part > be a starting point? I don't really have a roadmap how to deprecate 10 bit support. Because it is exported to userspace, the first question is if we can deprecate it, after all. But not much bandwidth even for that, currently. Happy hacking, Wolfram
