Subject: [PATCH v3] ARM: dts: pxa: add mioa701 board description

Add device-tree description of the Mitac MIO A701 board.
This is aimed at replacing mioa701.c board file, and once stabilized,
the leftover, such as the suspend resume mechanics will rely on a new
IPL, and not the legacy Windows CE one.

Signed-off-by: Robert Jarzmik <[email protected]>

Since v1: fix lcd_supply and lcd_backlight
These were depending on my internal tree changes, fit it.
Since v2: take into account Rob's comments

This patch deserves some special "love review". As it will probably
serve for a more broad pxa conversion to devicetree of the other boards,
and because it touches almost all domains for a pxa platform (camera,
video, audio, i2c, ...), it should be as clean as possible so that
mistakes are not carried on ...

Therefore I expect the review of this one to be long (ie. it won't land
for v4.19), until it looks good enough.

Cool, I did work on a Colibri PXA270 device tree off and on just never
came around submitting it. Yours is now definitely a good start!

Isn't that one supposed to be prefixed by pxa270-?

Wouldn't it rather make more sense to use CONFIG_MACH_PXA27X_DT
instead?

Usually, there is also a compatible for the particular board e.g.
"mitac,mioa701", not? You might have to check on the vendor prefix
though.

I guess usually, one would add newlines in front and between those
pinctrls but its kind of a matter of taste.

I believe pxa2xx.dtsi calls them uart rather than serial so unless you
plan to change this we will have to stick to using uart instead.

I also don't think those serial port labels buy us anything, so I would
get rid of them.

Uups, I guess that address is wrong, not? I will send a patch to fix it
in pxa27x.dtsi as well.

Haven't seen core_regulator before. Just regulator would do unless it
would be a more complex pmic.

While a few device trees seem to use audio-codec just codec would work
too.

I believe node names should not contain underscores therefore suggest
chaning snd_soc_pxa_audio to snd-soc-pxa-audio.

I guess that @0 is a legacy from when we used a fake regulator simple
bus and nowadays regulator-vmmc is more common.

Same for the @1 here and usually, for regulator labels the reg_ prefix
is used.

I guess it just missed the dependency on the following:

This is because you are missing at least this patch submitted earlier :
- [PATCH] ARM: dts: pxa: add pincontrol helpers

You're also missing the previous patches in the pxa/dt tree, which are already
on the trampoline for linux-next :
- git fetch github.com:rjarzmik/linux.git pxa/dt

Cheers.

Good point, for v4.

No, I'll have all the devicetree files under one config, for the PXA
architecture.

Ok, for this and all the following newlines.

There was a patch submitted for that earlier, at Rob's demand, to change these
names. That's another dependency on the pxa/dt tree.

As there are already in the .dtsi files, they don't hurt do they ?
