linux-sunxi/sunxi-next is a branch we maintain that has "most" new features
and patches aimed at the next release. It is not an official kernel branch,
nor is it always up to date (though we try to merge new things in).

mripard/linux sunxi/for-next is Maxime's sunxi branches, which is mostly
clock and dts patches.

You should always base your patches on the "next" branch of the maintainer
that will take your patches. In this case, ASoC:

    https://git.kernel.org/cgit/linux/kernel/git/broonie/sound.git/log/?h=for-next

There's also a sunxi topic branch:

    https://git.kernel.org/cgit/linux/kernel/git/broonie/sound.git/log/?h=topic/sunxi

Or you can just base them off linux-next.
