[PATCH v2 0/3] Device tree fixes for Axentia TSE-850 and Nattis

[PATCH v2 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.

Changes since v1:

- One more fix added to patch 1/3. The size of the rootfs partition
  should be 504MB, as the flash is 512MB total.

Sorry for the noise.

Cheers,
Peter

[PATCH v2 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.

All applied. I'm planning to send that for 4.17 as they are not urgent.

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

[PATCH v2 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.
