[PATCH 1/3] ARM: sunxi: add support for H2+ SoC

[Icenowy Zheng]

Allwinner H2+ is a quad-core Cortex-A7 SoC.

It is very like H3, that they share the same SoC ID (0x1680), and H3
memory maps as well as drivers works well on the SoC.

[PATCH 2/3] ARM: dts: sunxi: add Allwinner H2+ dtsi

[Icenowy Zheng]

Allwinner H2+ is a SoC so similar with H3 that H3 drivers and memory map
is known to work well on H2+, with both BSP kernel/firmware or the
mainline ones.

So add a dtsi file which only include the H3 dtsi only, so we can add
H2+-specified nodes in the dtsi file when we find any software
difference between H2+ and H3.

I agree that given that the chip-id is 1680 for both
this does seem to be the same die as the H3, and given
that we do not have any datasheets, I agree that just
treating the H2+ as a H3 is best for now, we can always
change h2.dtsi to actually differentiate things later.

This entire series LGTM and is:

I don't think we need that patch at all. You can do it just like we
did for the R8 and R16, just include the H3 DTSI in your board. We'll
create it if we need it at some point.

You can drop the drive and pull properties, and could you use the
generic pins and function properties for those nodes?

You can put the always on regulators (I'm guessing reg_vcc5v0 ?) here.

Icenowy,
Given that sunxi-next is currently broken for the pinctrl stuff,
you will need this patch to test, until Linus merges it:

    https://github.com/wens/linux/commit/e8ce92925a6dd1b2b38ed8699e81d0bc9804de20

AFAIK the regulator properties are optional the the USB PHY.
So we probably don't need to add it. Hans (CC-ed) could explain
his original intent?

Icenowy,
Given that sunxi-next is currently broken for the pinctrl stuff,
you will need this patch to test, until Linus merges it:

    https://github.com/wens/linux/commit/e8ce92925a6dd1b2b38ed8699e81d0bc9804de20

AFAIK the regulator properties are optional the the USB PHY.
So we probably don't need to add it. Hans (CC-ed) could explain
his original intent?

I've made the regulators optional exactly for boards like these,
where there is no regulator. Likely the Vbus is simply wired
directly to the 5V DC-in jack. So IMHO adding something like
the fixed reg_vcc5v0 a supply here just makes the dt
harder to read.

I've made the regulators optional exactly for boards like these,
where there is no regulator. Likely the Vbus is simply wired
directly to the 5V DC-in jack. So IMHO adding something like
the fixed reg_vcc5v0 a supply here just makes the dt
harder to read.

I've made the regulators optional exactly for boards like these,
where there is no regulator. Likely the Vbus is simply wired
directly to the 5V DC-in jack. So IMHO adding something like
the fixed reg_vcc5v0 a supply here just makes the dt
harder to read.

It also makes the regulator tree more complete and accurate because
you'd list all the devices that are needing those regulators. That
would also make it easier to deal with in the future.

But fair enough.
