[Maxime Ripard]

Hi,

This is the fourth version of the i2c compatible changes.

Changes from v4:
  - Added extra per-SoC compatibles to the DT for all SoC but the A10

Maxime Ripard (2):
  i2c: sunxi: Change i2c compatibles
  ARM: sunxi: dt: Convert to the new i2c compatibles

[PATCH v4 1/2] i2c: sunxi: Change i2c compatibles

[Maxime Ripard]

The Allwinner A10 compatibles were following a slightly different compatible
patterns than the rest of the SoCs for historical reasons. Move to the other
pattern for consistency across all Allwinner Socs.

[PATCH v4 2/2] ARM: sunxi: dt: Convert to the new i2c compatibles

[Maxime Ripard]

Switch the device tree to the new compatibles introduced in the i2c drivers
to have a common pattern accross all Allwinner SoCs.

I think I've addressed your comments in this version, are you ok with
these changes?

Any chance you merge this for 3.16? I guess I addressed your concerns
about the DT part.

Thanks!

I still don't prefer the removal of the old binding, but as this has
been discussed:

Applied to for-next, thanks!

I usually don't take dts updates, but I guess it makes sense this time,
because we dropped the old binding?

Either way is fine for me. It would be better to have the two patches
in the same tree, but I don't have any issue with merging it.
