Tested on 4.14.0-rc5-next-20171018+ 
I will try to check which uboot is used, perhaps it's an old uboot with some 
PMIC hack.

Schematics say PHY is power by DC1SW from the PMIC.
Not sure why you don't need that. Have you tested your patch?

Subjects should have "dts:" prefix.
We could probably fix it up for you.

Or our Q027, S027 boards, but final dts still are not complete.


Therefore no upstream boards are using it right now, so we'll merge it
when that will be the case.


I think the LCD connector on Banana Pi's uses parallel interface,
although the LCD should be an external DT overlay.

We had a couple of reports in Armbian forum about instabilities with NEO2 
that went away after downclocking the DRAM to 408 MHz (that's what Armbian 
uses currently on all Allwinner H thingies with just a single DRAM chip). 
FriendlyELEC started with 432 MHz on their single bank DRAM configurations 
last year and also lowered down to 408 MHz in the meantime.

But not where one would expect the change but somewhere else -- please see 
here: 
https://github.com/armbian/build/commit/b57c9d767ead528a54001d8728d39470e9faf5e4#commitcomment-23003991

I asked FriendlyELEC's Weidong right now to join the discussion providing 
some insights.

Best,

Thomas

What's the status of HDMI/SimpleFB driver for H5?

I don't see anything related to HDMI in linux-next dts files:

Hi Giulio,

If the board is available to buy, for general public use, then I think YES
it should go in as a separate DTS ;-).

I'd say no, do not merge if hardware is not publicly available, make a
separate DTS in your separate Tree that extends the board you are closest

Hi Giulio,

Sounds good to me.  I guess you are developing using the Olimex Lime board,
in which case the DTS patch is useless to anyone else?
