[GIT PULL] Renesas ARM Based SoC Fixes for v4.3

[Simon Horman]

Hi Olof, Hi Kevin, Hi Arnd,

Please consider these Renesas ARM based SoC fixes for v4.3.

These changes are required to restore working sound for the r8a779[01] SoCs
in v4.3.

My understanding is that with the inclusion of
"drivers: sh: Disable PM runtime for multi-platform ARM with genpd"
in v4.3-rc3 sound stopped working for the SoCs in question.

These patches were previously posted as part of
"Renesas ARM Based SoC DT Updates for v4.4".
I have withdrawn that pull request.


The following changes since commit 6ff33f3902c3b1c5d0db6b1e2c70b6d76fba357f:

  Linux 4.3-rc1 (2015-09-12 16:35:56 -0700)

    Really? I'm only seeing "power-domains" prop added...

    Oh, I understand now. The log seems somewhat poorly worded though...

I understood it right and merged it as is, but I agree this could
have been clearer.
