Declares the r8a7740 clocks supported by the legacy clock framework,
excluding those requiring extensions to the DIV6 driver, as well as
the Armadillo800-specific overrides.

Hi!
This one omits the funky DIV6 clocks because the corresponding changes to
the clock driver have not been accepted yet. It should not have any
negative impact on legacy support.

Hi Ulrich,
Thanks for you work on this. The contents of your patch look good to me
but I think the patch should be split up on a per-file basis.
* Documentation/devicetree/bindings/clock/renesas,cpg-mstp-clocks.txt
Although it only touches documentation this is a DT driver change.
I think it should go through Mike Turquette's tree. I have
CCed Mike to keep him in the loop.
As it is a DT change it should also be CCed to the
devicetree@vger.kernel.org. I have CCed them on this email
to keep them in the loop.
* arch/arm/boot/dts/r8a7740-armadillo800eva-reference.dts
This seems independent of the other changes although I assume
it doesn't do anything useful without some of the other changes
in place.
I can take this change through the renesas tree.
* arch/arm/boot/dts/r8a7740.dtsi
This seems to have a binding dependency on the
renesas,cpg-mstp-clocks.txt change. I think I can take
this once Mike has indicated he has merged that change.
It also seems to have a build dependency on the r8a7740-clock.h change.
I can take this change through the renesas tree.
* include/dt-bindings/clock/r8a7740-clock.h
I have a slight preference for it to be in a patch by itself rather
than bundled with the r8a7740.dtsi change even though it is a
dependency for that change.
I believe that I can take this change through the renesas tree.

Hi Ulrich,
Thanks for you work on this. The contents of your patch look good to me
but I think the patch should be split up on a per-file basis.
* Documentation/devicetree/bindings/clock/renesas,cpg-mstp-clocks.txt
Although it only touches documentation this is a DT driver change.
I think it should go through Mike Turquette's tree. I have
CCed Mike to keep him in the loop.
As it is a DT change it should also be CCed to the
devicetree@vger.kernel.org. I have CCed them on this email
to keep them in the loop.
* arch/arm/boot/dts/r8a7740-armadillo800eva-reference.dts
This seems independent of the other changes although I assume
it doesn't do anything useful without some of the other changes
in place.
I can take this change through the renesas tree.
* arch/arm/boot/dts/r8a7740.dtsi
This seems to have a binding dependency on the
renesas,cpg-mstp-clocks.txt change. I think I can take
this once Mike has indicated he has merged that change.
It also seems to have a build dependency on the r8a7740-clock.h change.
I can take this change through the renesas tree.
* include/dt-bindings/clock/r8a7740-clock.h
I have a slight preference for it to be in a patch by itself rather
than bundled with the r8a7740.dtsi change even though it is a
dependency for that change.
I believe that I can take this change through the renesas tree.

Hi Ulrich and Simon,
Thanks for your patch and review help. I've now spent some time giving
a try on top of:
renesas-devel-v3.16-20140808
[PATCH] ARM: shmobile: Partial build of pm-rmobile.c for multiplatform
[PATCH] ARM: shmobile: r8a7740: Multiplatform support
It seems that a couple of more changes are needed for the DTS and C to
boot the system, please see the mangled patch below for prototype
level example code.
Basically, to be able to boot the SCIF console needs to get clocks
assigned to it and the CMT needs to go from platform device to DT.
Actually, most leaf node MSTP clock assignment seems to be missing. I
maybe wrong, but I suspect some MSTP clock assignment can happen
before the DIV6 change gets in.
Ulrich, please work together with Simon to finalize the code! It is of
course up to you guys to decide how to split it, but perhaps Ulrich
can handle the clock assignment for the SCIF and other devices while
Simon gets to covert the CMT and TMU over. I've attached the
configuration I used to test your patch on top of the two above and
the local change below, hope it helps!
After this we need to merge the DTS for legacy and reference board
support. And build the DTB in case of Multiplatform. Then we should be
ready to kill of the DT reference C code. Not so far away!
Cheers,
/ magnus
