[PATCH v1 0/2] Tegra114: switch Tegra Note 7 from tn7 to tegratab

[Svyatoslav Ryhel]

Currently Tegra Note 7 uses tn7 compatible and device tree name which is
not quite correct. This device has proper codename which is tegratab.
Switch tn7 in compatible to tegratab and set a better device tree name
tegra114-nvidia-tegratab which aligns with newer trees.

[PATCH v1 1/2] ARM: tegra: set correct naming for Tegra Note 7

[Svyatoslav Ryhel]

Correct codename of Tegra Note 7 is "tegratab", while model
name should be "NVIDIA Tegra Note 7". Fix this inconsistency.

This is compatible, not codename. Change is meaningless, because
compatibles are just unique strings. Old string was fine.

Best regards,
Krzysztof

Which has nothing to do with compatible...

That part is fine.

Certainly news to me :-)

I have always known it as Tegra Note 7 and so 'tn7' as an abbreviation 
seems fine.

No mention of adding the chassis-type in the commit message. Seems like 
that should be a separate change.

Agreed. Along with Krzysztof's comments maybe this should just be a
single patch that updates the model property and adds the chassis-type.
We haven't used chassis-type before, but I see that the devicetree
specification has it marked as "optional-but-recommended", so maybe we
should make a pass over all files and add these as appropriate.
