Sorry, I meant: setting (or clearing) the extended temperature format is not supported. The extended temperature format itself is supported already. The proper mode is supposed to have been set by the BIOS/firmware. If for some reason this doesn't work for you, the proper way would be to pass the setting as platform data when you instantiate the device. If for some reason you can't do that, you can overwrite the configuration register using i2cset (from package i2c-tools) and the i2c-dev driver, before the tmp401 driver gets loaded. We _could_ add a module parameter or a sysfs attribute to select it, but this means extra code in the driver, and caution is needed because the value of many registers depend on the format so we would have to update them all at once to preserve existing settings. A module parameter would be suboptimal because all chips handled by the driver would need to have the same setting. Yet another approach would be to auto-select the range depending on which limits are set. This means even more code, but has the advantage to not introduce a new interface.
