Setting it as the default muxing for i2c2 would be great

Right, I checked the datasheet and it looks like this is the only pins where
i2c2 can be muxed to.

I will change it.

[PATCH 3/3] arm64: dts: allwinner: Add initial support for Pine64 PinePhone

[Ondrej Jirman]

At them moment PinePhone comes in two slightly incompatible variants:

- 1.0: Early Developer Batch
- 1.1: Braveheart Batch

There will be at least one more incompatible variant in the very near
future, so let's start by sharing the dtsi among multiple variants,
right away, even though the HW description doesn't yet include the
different bits.

This is a basic DT that includes only features that are already
supported by mainline drivers.

What are those incompatibilities? It's not really obvious from your
patch.

That's the default too, and I guess you'd need hardware flow control
here?

The changes are listed here:

https://wiki.pine64.org/index.php/PinePhone_v1.1_-_Braveheart#Changes_from_1.0

Substantial ones are:

2. Swap PC3 to FLASH_EN and PD24 to FLASH_TRIGOUT, where previously they were reversed
5. Set the EG25G's PWRKEY on by default (see resistor R1526)
6. Add R630 resistor location, populate with 0K by default. Allows adjusting to
   different battery thermistors in case this is not possible in software.

The incompatiblilities between 1.1 and 1.2 will be more extensive:

Yes, I made this and the 1.1 dts file by myself. It's not really a meaningful
contribution, since at the moment it's basically empty. I suppose to have
a license, the file requires some author.

Collaborative work is mostly in the dtsi.

For the record. Originally I took this file from:

https://gitlab.com/pine64-org/linux/commits/pine64-kernel-5.4.y
https://gitlab.com/pine64-org/linux/-/blob/pine64-kernel-5.4.y/arch/arm64/boot/dts/allwinner/sun50i-a64-pinephone.dts

about a month ago, and kept working on it in my trees for 5.5 and 5.6:

https://megous.com/git/linux/log/?h=pp-5.5
https://megous.com/git/linux/log/?h=pp-5.6

Adding support for using multiple cameras, bugfixing, and integrating work from
others, and now doing the legwork to strip the more complete DTS and make it
into a mainlainable state, so that collaboration can continue in the mainline
tree.

AFAIK, at this point (after stripdown), most of the work comes from Icenowy.
With some people contributing "smaller" things. I say "smaller" in quotes, since
I know that there can be a weekend of debugging behind changing a 2-3 lines, and
don't want to minimize anyone's contribution.

IANAL and I don't know what's entirely apropriate to do here. I've disucssed
this briefly on the IRC with involved people (that are also CCed in this
series), and there was a suggestion to adding a bunch of Cob/SoB tags, based on
some even older DTS file for dontbeevil (developer kit for PinePhone), that the
Icenowy's file was based on. So I did.

The more copyright holders the better, I guess. :) So if CCed people want to
be added here, and made the contribution to the present file, please state
so for the record again here on the mailing list, and I'll add you to the
header, or anywhere you wish.

Do you mean using a label? It seems label is deprecated, and bindings should
start using function/function-enumerator/color properties now:

https://elixir.bootlin.com/linux/v5.6-rc2/source/Documentation/devicetree/bindings/leds/common.yaml#L57

It doesn't look like the new bindings are used much, yet. I've found:

https://elixir.bootlin.com/linux/v5.6-rc2/source/arch/arm64/boot/dts/amlogic/meson-gxbb-kii-pro.dts

and

https://elixir.bootlin.com/linux/v5.6-rc2/source/arch/arm64/boot/dts/amlogic/meson-gx-libretech-pc.dtsi#L96

On PinePhone these are indicator leds with no pre-defined meaning, for
use by the apps to indicate things like a new SMS, or missed call, or
whatever people desire.

Actually it is not. There's not i2c2_pins at all in the mainline yet.

It's a common name for spring-loaded pin headers that can be used to connect the
phone to auxiliary devices. 6 pins are visible on this image near the top:

Hardware flow control is routed badly on the board, and can't be used at the
moment on any of the submitted versions. It may be added in 1.2.
