[GIT PULL] Renesas ARM Based SoC Boards Updates for v3.16

[Simon Horman]

Hi Olof, Hi Kevin, Hi Arnd,

Please consider these Renesas ARM Based SoC Boards Updates for v3.16.


This pull request is based on
3984ba10dddc5a10 ("ARM: shmobile: r8a7791: Rename VSP1_SY clocks to VSP1_S").

That commit is part of the pull request
"Renesas ARM Based SoC Clock Updates for v3.16",
tagged as renesas-clock-for-v3.16, which I have previously sent.

I have not rebased this pull-request on top of renesas-clock-for-v3.16
in order to avoid churn in linux-next.

The reason for basing this pull-request on clock updates is
that many of its patches depend on shmobile_clk_workaround() which
is added as part of the clock updates.


The following changes since commit 58ea1d53ba93620ac50fef9d9720b2323971f243:

  ARM: shmobile: r8a7791: Rename VSP1_SY clocks to VSP1_S (2014-04-14 11:30:11 +0900)

[PATCH 05/14] ARM: shmobile: koelsch-reference: Work around core clock issues

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@linux-m68k.org>

Due to issues with runtime PM clock management, clocks not explicitly
managed by their drivers may not be enabled at all, or be inadvertently
disabled by the clk_disable_unused() late initcall.

Until this is fixed, add a temporary workaround, calling
shmobile_clk_workaround() with enable == true.

For now this enables the clocks for: ether, i2c2, msiof0, qspi_mod, and
thermal. More clocks can be added if needed.

[PATCH 10/14] ARM: shmobile: bockw: remove old style audio clock

[Simon Horman]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Current audio clock didn't have dependency to device/driver,
but, it was not good design for DT support.
To avoid branch merge conflict issue,
it is using this load map, and this patch is 3) part.
 1) add new style clock in platform
 2) add new style clock method in driver
 3) remove old tyle clock from platform

    It is strange but this workaround doesn't seem to help me booting Koelsch
reference kernel with NFS root: it still crashes due to imprecise external 
abort once the userland starts. Only the actual drivers/sh/ fixing series by 
Ben/Geert helps with booting further. I therefore would like to have it merged 
by Simon the sooner the better...

    Unfortunately, I currently don't have time to find out what is wrong with
