[PATCH v2 2/3] ARM: dts: exynos: Add Google Manta (Nexus 10)
Posted by Lukas Timmermann 6 days, 8 hours ago
From: Alexandre Marquet <tb@a-marquet.fr>

Manta is the code name for Google Nexus 10, and was manufactured by
Samsung with their Exynos5250 SoC.
This patch adds initial device-tree file for this board.

Everything looks good in general, thanks for working on this. I have
few nits below. You can send next version whenever you are ready, but
just to let you know - my tree is already closed till RC1.

Please order the nodes in top level by node name (see DTS coding style).
I know that existing files do not follow that, but we try to have new
code conforming to the coding style.

Separate <> for each entry.

Are you sure you have this clock input? I think on Exynos5250 usually
only XXTI was provided, no?

Just "pwrseq"

First of all, thank you!
The as3668 bindings are yet to be applied, no need to rush here.

We ordered them as seen in other devices. I've checked out the coding style 
guideline and will make modifications accordingly.

We checked with the downstream code and found this clock input. We
recognize, that downstream kernels aren't 100% correct at times.
I tested the device without this clock input as you suggested.
It seems that this is in fact not needed. So I will remove it in v3.

Just out of curiosity. Why is that?

You have only one pwrseq device, so not need to precise which one is
that and node names should be generic.
