This is the sun5i / a13 version of sun8i-q8-common.dtsi for use in dts
files for a13 q8 based tablets. Compared to sun8i this uses uart1 for the
serial console, and PG0 for card-detect for mmc0.
This also adds pmic and otg support, which both use the same config on
all known q8 a13 devices. This is not present in sun5i-q8-common.dtsi
because pmic / otg support for sun8i has not yet been merged.

Are we going to have any user but the one you posted in the patch 3
planned?
Depends on what I can get my hands on / what is in the post atm.
One difference in fex files of different 18 variants is how the usb wifi is
powered, either via a gpio or via ldo3. Also there are differences in which
accelerometer is used, so eventually I expect there to be several users
of this dtsi.
But no difference in the SoC used (A13 vs A10s)?
I'm not sure having 18 DTs for a single board name is going to be
really helpful.
Sorry I meant to write q8 not 18 :)
It would be something to be supported by some quirks
mechanism, instead of having to require the user to pick the right one.
Agreed, which is why I added a generic sun5i-a13-q8-tablet.dts, which
can then later be extended with quirks and such to get all the different
variants supported. Which I guess means that the contents of
sun5i-q8-common.dtsi can be folded into sun5i-a13-q8-tablet.dts, otoh
we may have some special cases which do require a separate dts and
having sun5i-q8-common.dtsi follows the same scheme as used for the
a23 / a33 tablets. In the future we should probably also add
sun8i-a23-q8-tablet.dts and sun8i-a33-q8-tablet.dts files and make
the existing ones just empty files with a single #include for
compatibility.
If possible I would like to at least have you queue up the default
sun5i-a13-q8-tablet.dts so that we've a dts file for a13 based tablets
which at least gets the basics going.
Either in its current form, or with it and sun5i-q8-common.dtsi
squashed together. If you want a squashed version let me know and
I'll do a resend.
Are you coming to ELCE ? I think the both of us should go to:
http://lceeu2015.sched.org/event/999c45c7fe78824a88269f35539c7e5c#.VfGcCLPYqlM
(Device Tree NG BoF) and try to hash out a solution for this there,
the quirks / variants stuff sounds good, but I wonder how far along
that is ?

Hans
