Please cull the marketing from the descriptions. "Industry leading" may
or may not be accurate at the time of going to print, but might be
completely incorrect in 5 years. Ditto "low power consumption".

With the marketing gone,

Seems like having a website like
https://wiki.analog.com/resources/tools-software/linux-drivers/input-misc/adxl345
would make more sense than a generic forum for all of your drivers?
