Dave Jones 931db6a32d [CPUFREQ] Clean up convoluted code in arch/x86/kernel/tsc.c:time_cpufreq_notifier()
Christoph Hellwig noticed the following potential uninitialised use:

 > arch/x86/kernel/tsc.c: In function 'time_cpufreq_notifier':
 > arch/x86/kernel/tsc.c:634: warning: 'dummy' may be used uninitialized in this function
 >
 > where we do have CONFIG_SMP set, freq->flags & CPUFREQ_CONST_LOOPS is
 > true and ref_freq is false.

It seems plausable, though the circumstances for hitting it are really low.
Nearly all SMP capable cpufreq drivers set CPUFREQ_CONST_LOOPS.
powernow-k8 is really the only exception. The older CPUs were typically
only ever UP. (powernow-k7 never supported SMP for eg)

It's worth fixing regardless, as it cleans up the code.

Fix possible uninitialized use of dummy, by just removing it,
and making the setting of lpj more obvious.

Thomas Renninger cef9615a85 [CPUFREQ] ondemand: Uncouple minimal sampling rate from HZ in NO_HZ case
With this patch you have following minimal sampling rate restrictions:

Kernel restrictions:
If CONFIG_NO_HZ is set, the limit is 10ms fixed.
If CONFIG_NO_HZ is not set or no_hz=off boot parameter is used, the
limits depend on the CONFIG_HZ option:
HZ=1000: min=20000us  (20ms)
HZ=250:  min=80000us  (80ms)
HZ=100:  min=200000us (200ms)

HW restrictions:
Do not sample/poll more often than HW latency * 100  exported by the low
level cpufreq HW driver

The higher value of above restrictions is the minimal sampling rate
that can be set (and can be seen via ondemand/sampling_rate_min sysfs file)

Default sampling rate still is HW latency * 1000, but this will now end
up in lower values on latest (Intel and AMD) hardware as these can switch
really fast and sampling rate mostly was limited to the 80ms or 200ms
(depending on whether HZ=250 or HZ=1000 is used).

  * Cruft written to the clock registers (seemingly harmless but Not
Good (tm))

It also eliminates some unnecessary ifs and tidies the loop syntax.

Thanks to Philipp Zabel who discovered the divider issue, commenting

   "Except for the SDCLK = HCLK (divider bypassed) case, the clock
    setting resulted in double the requested frequency.
    The smallest possible frequency (f_max/512) is configured with

ASIC3 can disable the memory, so we need to wait for mfd_cell->enable
to enable the memory before we can map the SD control registers.

Use an IRQF_TRIGGER_ flag in request_irq instead.

Philipp Zabel 5e74672c09 tmio_mmc: add bus_shift support
Some ASIC3 devices in the wild are connected with the address bus shifted
by one line, so that its 16-bit registers appear 32-bit aligned in host
memory space.

Philipp Zabel f0e46cc497 MFD,mmc: tmio_mmc: make HCLK configurable
The Toshiba parts all have a 24 MHz HCLK, but HTC ASIC3 has a 24.576 MHz HCLK
and AMD Imageon w228x's HCLK is 80 MHz. With this patch, the MFD driver
provides the HCLK frequency to tmio_mmc via mfd_cell->driver_data.
