Hi all,
Some of you may have heard of a tool we use inside TI for debugging on
OMAP. It's a nice userspace tool which can inspect many aspects of
hardware state called "omapconf". The tool has just been open sourced
and can be found at:

such example is an adjustable-rate root clock. Ensure that

As a proof-of-concept, convert the existing smp_twd code to use clk
notifiers in place of CPUfreq notifiers. This works out nicely for
Cortex-A9 MPcore designs that scale all CPUs at the same frequency. For
chips which can scale frequency independently this change makes
From: Linus Walleij <(address hidden)>
The localtimer's clock changes with the cpu clock. After a
cpufreq transition, update the clockevent's frequency and
reprogram the next clock event.
Adds a clock called "smp_twd" that is used to determine the
twd frequency, which can also be used at init tim
From: Mike Turquette
The ARM periphclk drives various peripherals for the MPU including the
TWD and local timers. This patch creates the missing clk tree data to
represent this relationship:
dpll_mpu_ck
|
dpll_mpu_m2_ck (divide by 1)
|
mpu_clk (divide by 1
(with 38.4MHz
SYS_CLK). Using CPUfreq to set the MPU to this rate puts the MPU into
Low Power Bypass, which triggers the __clk_reparent code in
drivers/clk/clk.c, which migrates the dpll_mpu_ck directory (and all of
its subdirs) to the div_mpu_hs_clk dir under dpll_core_ck.

HACK: omap: opp: add fake 400MHz OPP to bypass MPU
omap: clk: .round_rate
which simplies passing up a rate change
request to the parent.
Not for merging, just to get discussion going around the common clk
patches and future OMAP adaptations.

This series will be followed up shortly with another set of patches for
"testing" the clk rate change notifiers, parent propagation of rate
changes and debugfs re-parenting.

The common clk framework is an attempt to define a generic struct clk
which most platforms can use to build a clk tree and perform a set of
well-defined operations.

The common clk framework provides clk_prepare and clk_unprepare
implementations. Create an entry for HAVE_CLK_PREPARE so that
GENERIC_CLK can select it.
