It h= as applications in electronic equipment, personal computers, wearables, and= HVAC. The datasheet can be found here: https://ams.com/documents/20143/360= 05/AS621x_DS000677_4-00.pdf I wish to write a driver for this device and contribute it to the kernel, a= s my first module. It being my first module, I wanted to make sure that thi= s was a worthy use of everyone's time and that it could be useful at some p= oint. Sparkfun provides a convenient breakout board already, which is the o= ne that I will be using. After searching through the mailing list archive, I found a set of patches = from 2016 for the AS6200 as part of the iio subsystem. For reasons I could = not find, the driver never got merged. I guess the original developers move= d on to something else. Additionally, they were discussing towards the end = how the hwmon subsystem may have been a better fit for the driver. Therefor= e, I wanted to hear everyone's thoughts on writing this driver before I get= started on it. From what I can tell, it does not seem much more complex th= an some other temperature sensor drivers in the kernel, such as the tmp102. Regards, Joe Strauss
