Add the ADC low and high resolution configuration and which one to use.

Hi,

This patch is a split from this set of patches:
http://thread.gmane.org/gmane.linux.ports.arm.kernel/206130/focus=6321

Then device tree changes can go through ARM-SOC and driver changes through the
iio subsystem.

Regards

Ludovic

I am guessing the IIO side is to follow.  Even when posting series where it different
bits are to go through different trees, it is useful to have them in one series so that
people can see the whole result.

Yes, a v2 series is coming. In fact, I asked Ludovic to post his .dtsi
modifications separately because:
- From the fist discussion, it seemed that we reached a consensus and
that the current binding is okay
- I have to reassemble a pull-request to arm-soc maintainers for 3.10
and it seems that is is time to collect all material.

So, I plan to stack this update of AT91 device tree files real soon. If
you want to give me your acknowledgement once you have read the whole
series, let me know...

Best regards,

I agree too

Ludo please resend the whole series

Consensus is probably putting it a bit strongly given Maxime's comments
but as there was no specific alternative suggested and they Maxime
was raising general issues rathe rthan specifics, I'll take the
iio side of these as is.
