Hi,
This patch series adds support for a new set of boards, codenamed
"midas". These are the Galaxy S3 (m0/m3, GT-I9300/GT-I9305)
and the Galaxy Note 2 (t0, GT-N7100/GT-N7105).
These boards are closely related to trats2 - m0 is a trats2 but with a
bootloader geared towards booting Android rather than a traditional Linux
distribution - and because of this, the dts files are largely based off
what is already in-place for trats2. Trats2 is modified to use
the dts files added by this series.
Patch #1 adds documentation for the bindings used by the boards.
Patch #2 splits the existing trats2 DTS into the common midas,
m0/m3/trats2-specific, and trats2-specific parts.
Patch #3 adds the device-tree files for the other boards.
Patch #4 enables cpuidle support for all added boards.
Changes since v1:
* Include trats2 in inheritance
* Add the new dtbs to the makefile
* Cleanup style per Krzysztof's comments
Changes since v2:
* Rebase on linux-next 20171218 (adds some fixes yet to land in mainline)
* Leave any changes to the DTS out of patch #2
* Minimise diff of exynos4412-midas.dtsi, using format-patch -B30%
(thanks for the suggestion, Krzysztof)
* Leave original trats2 copyrights on midas and galaxy-s3 DTS files
* Preserve ABI for the cpuidle compatability check
* Explain the m0/m3/t0 -> GT-I9300/GT-I9305/GT-N7100/GT-N7105 relationship
in the DT binding docs.
Cheers,
Simon

The midas boards share a lot with trats2. Split the common parts
out of trats2 into a common midas dtsi and a common "galaxy s3" dts.

"midas" is the codename for a family of smartphones released by Samsung
Mobile. It includes the Galaxy S3 (GT-I9300/I9305) and the Galaxy
Note 2 (GT-N7100/N7105). The boards largely have the same peripherals:
the main differences are touchscreen, display panel and cellular modem.

Exynos4412 can only use cpuidle when running under a compatible
bootloader/firmware. The midas family of boards, including trats2,
have such a firmware, so allow them to use cpuidle.
Leave the trats2 check there in order to preserve the ABI.

This looks incorrect. Not every midas board is trats2... Unless that
was left here for compatibility purpose but then it would be good to
see explanation.

I do not get this node. It sits in midas.dtsi and s3.dtsi just enables
it. Why not enabling it here?

Regulator should not be disabled or enabled. It is not a device. I do
not get the logic behind...
The ''status = disabled" usually is added in DTSI files to nodes which
are not fully configured at this point, e.g. they require external
resources (clocks, regulators). These external resources will be
provided when extending in DTS (or further DTSI) while enabling it.
However regulator has always all necessary resources.

Ditto.

I think each board has the same memory so maybe this can be made part
of midas.dtsi?

Initially, I thought that T0 had some extra regulator that needed to be enabled,
but in reality it's just a different vdda supply - so vdda should be
moved down to galaxy-s3

In this case, s3 and t0 have different regulator voltages/names
(3.0V vs 2.8V), but it doesn't really seem to make sense to me
to leave ldo25 out of the common dts altogether, since it's there on all
boards. If you would prefer, I can remove ldo25 and leave it completely
in the t0/s3 config files

T0 and M3 have 2GB of RAM, trats2/M0 have 1GB.

Handled by the bootloader - to work around the proprietary bootloader not
supporting device tree and requiring hacks to successfully boot a
mainline kernel, i'm using kexec from a suitably patched kernel to load
and boot the "real" kernel. (This also means one image can be used
across all boards).

Yes, please and then only for s5c73m3@3c. The i2c node should stay
enabled, I think.

So leave empty ldo25, like:
ldo25_reg: LDO25 {
regulator-name = "LDO25";
};
Something like buck8_reg in
arch/arm/boot/dts/exynos4412-odroid-common.dtsi. The point is to
provide entire description of max77686 regulators in basic DTSI. The
driver anyway knows the constraints (min/max voltages) so in case of
missing entries in DTS, default will be applied. Then in child-DTS you
can customize the voltage and/or name to necessary value.
Best regards,
Krzysztof

Could you document it in DTS why bootargs are missing?

If you're going to change it, use an SPDX tag.

Do you have any example of a better description? All the other ARM board
descriptions seem similarly terse.
Alternatively, maybe changing the compatible strings is a better
solution? "samsung,n710x" for t0, "samsung,i9300" for m0, and
"samsung,i9305" for m3?
Cheers,
Simon

I initially did this in v2[1], but Krzysztof said to keep
the trats2 copyright header, since the galaxy-s3 dts is a
subset of the old trats2 DTS. Is adding the SPDX tag and
keeping the Samsung copyright stanza the preferred approach
here?

Yes, but I was referring only to copyright header. The SPDX tag
replaces the license, not the copyright.

Yes, it was the compatible string I was commenting on. I don't really
care about the description because for most boards I have no idea what
they are.
