Hi Maxime,
Yesterday I've been playing a bit with my Mele A1000G Quad, with the purpose of
trying to get usb and mmc working there. I already have wens' gmac patches for
the
A31 in my tree, so for starters I tried to get that to work.
Unfortunately the fex shows that the phy is powered by dldo1 from the pmic, and
by
default that is configured to off. So I got stuck there wrt getting the gmac to
work
on the A1000G Quad / M9.
Do you know if anyone is working on pmic support for the A31, or for the new
push-pull
serial bus this uses?
Is this bus similar enough to i2c that we can use the i2c subsys for this,
maybe with
an extra controller flag, or do we need to likely write a whole new subsys for
this ?
Also do you know of a datasheet for the AXP221 somewhere ?
There is a Chinese version datasheet in github
https://github.com/OLIMEX/OLINUXINO/tree/master/HARDWARE/A31-PDFs
Ah, that is good to know.
I created an AXP221 page on the wiki: http://linux-sunxi.org/AXP221
I put in most of the tables from the datasheet. A lot of it was
copy-pasted from the AXP209
page, then updated and cleaned up. The register ranges remain mostly
the same, however some
bit offsets were moved around, and some value ranges were changed.
The regulators, interrupts, and most of the registers should be
complete. I know the battery
level stuff is still missing. And all the wording and figures are
still missing as well.
Hopefully I'll finish the translation this week.
If anyone wants to help:
1. upload the datasheet to the linux-sunxi site, and update the link
at the bottom.
Done
2. copy the figures: application, pin layout, and functional diagram
they are on pages 7, 8, and 12.
And done.
Cheers
ChenYu
