Aren't the MFD cells probed in order?

In that case, it makes little sense to short order them for this
particular device (X-Powers PMICs in general). It will just make the
system boot slower because of probe deferring.

Why? As explained by Chen-Yu in v3[1], axp-gpios can be muxed as
regulators, thus should be probed before axp-regulators. axp-adc is
often used by axp-battery, axp-usb-power, axp-ac-power, thus should be
probed beforehand as well.

For the alignment that also triggered your OCD, I can send you a patch
the day you merge this one if it can help. I sent a few patches for this
driver that didn't respect the alignment so I'm fine fixing the mfd
cells (and eventually re-order them as I saw a few axp-gpio cells being
declared after axp-regulators).

Does that make this patch OK for you, Lee?

Thanks,
Quentin
