[linux-sunxi][PATCH 0/3] Enable SPDIF on the Mele I7

[codekipper at gmail.com]

From: Marcus Cooper <codekipper@gmail.com>

Hi All,
here is the patch set required to enable SPDIF on the Mele I7 which is
a A31 based TV-box. To get this working a fix has to be applied to the
clock driver and this will be pushed seperately.

For now the dtsi changes can be applied and when the clk change is
merged then we can finialise this push by applying the I7 patch.
BR,
CK

That property isn't documented anywhere, and doesn't seem to be used
in your driver either.

On a separate topic, is the channel inversion bug also found on the
A31?

Ooops....do you want me to respin a new patch or will you do your
magic with 'dd'? It fell through the cracks as it was cherry picked
from my dev branch where I was at one time playing with spdif-in. This
has pretty much been relegated to the bottom of my todo/finish list.

I have seen this and I'm sure that was also on my A31 hardware but
I've just fired her up and the speaker test worked as expected. I also
repeated the test on my A10 device and didn't hear the issue.

Sorry, it's C-w for me :)

I fixed and applied.

This patch should be ready to be merged. The associated clk
