Subject[PATCH v4 2/5] arm64: dts: exynos: make tm2 and tm2e independent from each other
Message-ID<sWBbX-1l7-7@gated-at.bofh.it>
Currently tm2e dts includes tm2 but there are some differences
between the two boards and tm2 has some properties that tm2e
doesn't have.

That's why it's important to keep the two dts files independent
and put all the commonalities in a tm2-common.dtsi file.

At the current status the only two differences between the two
dts files (besides the board name) are ldo31 and ldo38.

Thanks. Now I can easily see the differences... and there are
differences! This is much, much easier to review then all previous
versions.

I understand that you added the label to create LDO31 and LDO38
regulators in specific DTS (I read your comments below). I do not have
strong opinion but I would prefer overriding in DTS instead of new addon, so:
1. without the label above,
2. with something like:
	ldo31_reg: LDO31 {
		/*
		 * LDO31 differs from target to target,
		 * its definition is in the .dts
		 */
	};

With such empty stub, one can still find all the regulator nodes in
common DTSI. I find it more readable. What do you think?

Best regards,
Krzysztof

Patch looks good to me.

You ended with the wrong model and compatible for TM2.

Speaking about these, I noticed that the common .dtsi has the TM2 model and
compatible. I think those don't belong to .dtsi files and instead should be
defined on each .dts file.
