[PATCH 0/3] Device tree fixes for Axentia TSE-850 and Nattis

[Peter Rosin]

Hi!

Here's a series that is of the "documentation" kind. It fixes things
that don't really need fixing, but the fixes are correct none-the-less
and should prevent possible confusion.

Cheers,
Peter

[PATCH 1/3] ARM: dts: at91: nattis: use up-to-date mtd partitions

[Peter Rosin]

The nattis currently relies on the cmdline to correctly configure the
MTD partition table, and the one given in the device tree is simply
ignored. Which is fortunate, since the device tree partition table is
bonkers and does not match reality.

So, in order to avoid confusion, fix the device tree partition table
to match what is expected (i.e. what is normally provided on the cmdline).
In particular, the rootfs partition should be mtd6.

Shouldn't it be simply removed then?

Hmm, that's a thought! Less is more, and all that. However, I think I
rather have it in the device tree anyway. Then I have the option to
drop a lot of tedious cmdline args in the future.

Cheers,
Peter

The lvds encoder chip was omitted by oversight. Add it.

[PATCH 3/3] ARM: dts: at91: tse850: make the sound dai cell count explicit

[Peter Rosin]

The node is referred to as a DAI from the sound node and should
therefore have a #sound-dai-cells property.
