Absolutely would be interested to try and test that on my ERD850 device,
feel free to send patches/instructions my way.

On another side note, I noticed that on the e850-96 you setup basic PMIC
functionality in u-boot, on ERD850 we also do a similar thing via a
secondary bootloader (uniLoader), was curious to know whether you or Sam
have tried implementing PMIC capabilities into the Linux kernel at all and
if so how successful or unsuccessful has it been?
