This work is based on previous work by Dan Murphy [0] who is working on other tasks at the moment, so I will be helping to continue upstreaming this driver. This is more of a re-write than a continuation and there are many changes so I am submitting this as a v1. This device is very similar to the AFE4403 and I was originally planning on pushing the two drivers together with common core functions in a third file. The AFE4403 driver is still being tested so I merged common code back into this driver, this is why this driver may seem a bit unnecessarily modular. I will probably split this stuff back out when I push the AFE4403. I also had some issues with sysfs naming for the channels; this device has three input channels from three LED stages and two ambient channels based on the LED stages. This might have been be a good place for using IIO modifiers[1], but we also have two differential channels based on the ambient channels, and channels cannot have both modifiers and be differential (the modifier is stored in the differential channel's ID field?). So I used sysfs names that would be close to what they would be if IIO supported these things.
