[PATCH v5 00/14] arm64: renesas: add sound support

[PATCH v5 00/14] arm64: renesas: add sound support

[Simon Horman]

Hi,

these patches add sound support to the r8a7795/Salvator-X.

These patches are an update of work by Kuninori Morimoto,
broken out of a larger patchset posted by him.

The main change to the patches themselves since Morimoto-san's v3 posting
and v4 updates to that posting is to update to new CPG/MSSR bindings via
Geert Uytterhoeven.

Morimoto-san, I would be most grateful if you could look over this and repost
if there are problems.

Base:

* "[PATCH v4 0/3] arm64: renesas: r8a7795: add I2C support"
  This can be found in the topic/r8a7795-i2c-v4 branch of
  my renesas tree on kernel.org.

Availability:
* This patchset is available in the  topic/r8a7795-sound-v5 branch of my
  renesas tree on kernel.org

I have posted this cs2000 driver to clk ML, but not yet accepted.
And new version can't use "clock-frequency".
Actually, Salvator-X sound can work without cs2000,
but it can be limited sound rate
Do you want to avoid cs2000 until it was accepted ?
Then, I can create and post whole patch set.
Or we can avoid sound support so far ?

If we can have partial sound support without cs2000 now,
and then fuller support with cs2000 later, then that seems
like a good way to proceed to me.
