It's just the way it is currently for AXP209 and AXP22x so did the same for AXP813. I'll add DT "support" in next version for all AXPs supported by this driver. Or is it worthy of a small separate patch series? Thanks, Quentin -- Quentin Schulz, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com

Hmm... Why would you map the IIO channels from the ADC? I thought those were all accessible from userspace? However, proper muxing of the GPIO pin to the ADC function makes sense. ChenYu
