Hello Jean, Hans, here is my first work at TI's 401/411 temperatur sensor. The patch(es) aren't intented to be applied. I just want some comments and maybe real testing by Hans. The first patch is the original one from Hans sent to me. The second patch contains some work of Hans' students. I've brought it in shape. The driver now has multichip support in the usual way. TODO: Update Kconfig Writing documentation There are a few remaining questions. 1. Hans' students implemented two additional sysfs entries (tempX_[lowest|highest]). The TMP411 chip has some additional registers for minimum and maximum temperatures measured since power-on and chip-reset. AFAIK there are no standard sysfs entries for these values. I don't remove the support so far. Should it be removed? Are there other chips with such features? 2. There is another command to reset the chip. Is this a useful feature? 3. Indentation What is the right way to indent arguments in function declaration? a) static int tmp401_probe(struct i2c_client *client, const struct i2c_device_id *id) b) static int tmp401_probe(struct i2c_client *client, const struct i2c_device_id *id) My emacs prefered the first one, but sometimes this doesn't look very well. 4. May I add a copyright note of me in the header? Again, thank you very much for your help. It's a pleasure to work with you. Thanks, Andre
