Split the DPLL3 M2 divider clock functions out of clock34xx.c and move
them into mach-omap2/clkt34xx_dpll3m2.c. This is intended to make the
clock code easier to understand, since all of the functions needed to
manage the OMAP3 DPLL3 M2 divider are now located in their own file,
rather than being mixed with other, unrelated functions.
Clock debugging is also now more finely-grained, since the DEBUG macro
can now be defined for the DPLL3 M2 clock alone. This should reduce
unnecessary console noise when debugging DVFS.
Also, if at some future point the mach-omap2/ directory is split
into OMAP2/3/4 variants, this clkt file can be placed in the mach-omap34xx/
directory, rather than shared with other chip types that don't use this
clock type.
This patch also lays the groundwork to skip compilation of this
code on OMAP3 chips that don't support DVFS (e.g., AM35xx) via
the Makefile, rather than via #ifdefs.

First, this patch adds new worst-case latency values to the
omap_device_pm_latency struct. Here the worst-case measured latencies
for the activate and deactivate hooks are stored.
In addition, add an option to auto-adjust the latency values used for
device activate/deactivate.
By setting a new 'OMAP_DEVICE_LATENCY_AUTO_ADJUST' flag in the
omap_device_pm_latency struct, the omap_device layer automatically
adjusts the activate/deactivate latencies to the worst-case measured
values.
Anytime a new worst-case value is found, it is printed to the console.
Here is an example log during boot using UART2 s an example. After
boot, the OPP is manually changed to the 125MHz OPP:
[...]
Freeing init memory: 128K
omap_device: serial8250.2: new worst case deactivate latency 0: 30517
omap_device: serial8250.2: new worst case activate latency 0: 30517
omap_device: serial8250.2: new worst case activate latency 0: 218139648
omap_device: serial8250.2: new worst case deactivate latency 0: 61035
omap_device: serial8250.2: new worst case activate latency 0: 278076171
omap_device: serial8250.2: new worst case activate latency 0: 298614501
omap_device: serial8250.2: new worst case activate latency 0: 327331542
/ # echo 125000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed
omap_device: serial8250.2: new worst case deactivate latency 0: 91552
Motivation: this can be used as a technique to automatically determine
the worst case latency values. The current method of printing a
warning on every violation is too noisy to actually interact the
console in order to set low OPP to discover latencies.
Another motivation for this patch is that the activate/deactivate
latenices can vary depending on the idlemode of the device. While
working on the UARTs, I noticed that when using no-idle, the activate
latencies were as high as several hundred msecs as shown above. When
the UARTs are in smart-idle, the max latency is well under 100 usecs.

Add usecounting for wakeup and sleep dependencies. In the current
situation, if several functions add dependencies on the same
clockdomains, when the first dependency removal function is called,
the dependency will be incorrectly removed from the hardware.
Add clkdm_clear_all_wkdeps() and clkdm_clear_all_sleepdeps(), which
provide a fast and usecounting-consistent way to clear all hardware
clockdomain dependencies, since accesses to these registers can be
quite slow. pm{2,3}4xx.c has been updated to use these new functions.
The original version of this patch did not touch these files, which
previously wrote directly to the wkdep registers, and thus confused
the usecounting code. This problem was found by Kevin Hilman
<khilman@deeprootsystems.com>.
N.B.: This patch introduces one significant functional difference over
the previous pm34xx.c code: sleepdeps are now cleared during
clockdomain initialization, whereas previously they were left
untouched. This has been tested by Kevin and confirmed to work.
The original version of this patch also did not take into
consideration that some clockdomains do not have sleep or wakeup
dependency sources, which caused NULL pointer dereferences. This
problem was debugged and fixed by Kevin Hilman
<khilman@deeprootsystems.com>.

Move clockdomain wakeup dependency and sleep dependency data

this is not such a big problem, but for OMAP4 this needs to be fixed.
