Hi all,

Changes since 20150129:

The arm-soc gained conflicts against the arm-current and arm trees.

The spi tree gained a build failure for which I reverted a commit.

Non-merge commits (relative to Linus' tree): 6300
  6348 files changed, 255117 insertions(+), 131620 deletions(-)

I see the following runtime warning repeatedly (with different call
paths to vexpress_osc_round_rate) with my qemu vexpress test.

Bisect points to commit cb75a8fcd14e71 ("clk: Add rate constraints to clocks").

Will try the patch after FOSDEM.

Hi Geert,

thanks a lot for the pointer.

Stephen Boyd's patch ("clk: Assign a requested rate by default")
fixes the problem seen in my test. Stephen, please feel free to add

Tested-by: Guenter Roeck <linux@xxxxxxxxxxxx>

to that patch.

Thanks,
Guenter
