This series is an attempt to move clock support on Samsung
S3C64xx
SoCs
to Common Clock Framework.
First, support for PLL types present on S3C64xx SoCs is added
to
Samsung Common Clock Framework driver. Then the main clock
driver
for mentioned SoCs is introduced. Further patches contain
fixes
for drivers to make them compliant with CCF semantics,
migration
of platform code to use the new clock driver and removal of
old
clock management code.
Depends on:
- [PATCH v4 00/20] Samsung PWM support cleanup
http://thread.gmane.org/gmane.linux.kernel.samsung-soc/20
856
On S3C6410-based Tiny6410 board (Mini6410-compatible):
Tested-by: Tomasz Figa<tomasz.figa@xxxxxxxxx>
For v1:
Acked-by: Mike Turquette<mturquette@xxxxxxxxxx>
Changes since v1:
- added patch for read-only muxes,
- exported configurable muxes and dividers,
- defined mout_syncmux as read-only mux,
- in DT-enabled case fixed-clock binding is used to define
external clocks.> >>>
Tomasz Figa (8):
clk: mux: Add support for read-only muxes.

Basically, this series looks good to me, but I'm not sure how
this
should be handled because of dependency with PWM cleanup and
clk
stuff
in clk tree now...
Patches 1-3 can go into the clk tree. 4-6 should go through
their
respective trees.
If you want I can take 7& 8 through the clk tree.
Alternatively I can provide patches 1-3 in a separate stable
topic
branch for you to pull in as a dependency. We'll both merge that
stable
topic branch into our trees and you can make a note of it for
the
arm-soc folks.
Thanks for your quick response. Would be helpful to samsung tree
if
you
could provide a separate stable topic branch what you suggested
for
clk
stuff in this series.
git://git.linaro.org/people/mturquette/linux.git clk-next-s3c64xx
Topic branch contains patches 1-3 of this series on top of
v3.11-rc2. I
have already merged the same into the clk-next branch.
Mike, thanks. I've merged the branch 'clk-next-s3c64xx' into the samsung
tree :)
What about the dependency on PWM cleanup series? Patches 7-8 must be
merged after them, otherwise there will be a regression, because the
old PWM clocksource driver will be broken and so s3c64xx won't boot
until moved to new one, which is done by mentioned series.
Is this a question for me? I did not take patches 7 or 8 into clk-next.
Sounds like those patches should go through Samsung tree into arm-soc,
and perhaps be a late-applied branch to get the ordering right.
It's just continuation of the topic. I guess the question is mostly for
Kukjin. Anyway, your suggestion is most likely the right thing, thanks.
Tomasz, I can handle. Thanks.
- Kukjin
