cpufreq: rename index as driver_data in cpufreq_frequency_table

2013-06-04T12:25:59+00:00

The "index" field of struct cpufreq_frequency_table was never an
index and isn't used at all by the cpufreq core.  It only is useful
for cpufreq drivers for their internal purposes.

Many people nowadays blindly set it in ascending order with the
assumption that the core will use it, which is a mistake.

Rename it to "driver_data" as that's what its purpose is. All of its
users are updated accordingly.

sh: extend clock struct with mapped_reg member

2011-12-09T09:01:05+00:00

Add a "mapped_reg" member to struct clk and use that
to keep the ioremapped register based on enable_reg.

sh: clkfwk: Kill off remaining debugfs cruft.

2011-11-11T07:11:41+00:00

Now that all of the named string association with clocks has been
migrated to clkdev lookups there's no meaningful named topology that can
be constructed for a debugfs tree view. Get rid of the left over bits,
and shrink struct clk a bit in the process.

sh: clkfwk: add clk_rate_mult_range_round()

2011-11-04T15:49:27+00:00

This provides a clk_rate_mult_range_round() helper for use by some of the
CPG PLL ranged multipliers, following the same approach as used by the
div ranges.

drivers: sh: late disabling of clocks V2

2011-06-24T07:27:07+00:00

This V2 patch changes the clock disabling behavior during boot.
Two different changes are made:

1) Delay disabling of clocks until late in the boot process.
   This fixes an existing issue where in-use clocks without
   software reference are disabled by mistake during boot.
   One example of this is the handling of the Mackerel serial
   console output that shares clock with the I2C controller.

2) Write out the "disabled" state to the hardware for clocks
   that not have been used by the kernel. In other words,
   make sure so far unused clocks actually get turned off.

drivers: sh: resume enabled clocks fix

2011-06-14T06:15:25+00:00

Extend the SH / SH-Mobile ARM clock framework to only
resume clocks that have been enabled.

Without this fix divide-by-zero is triggering on sh7372
FSIDIV during system wide resume of Suspend-to-RAM.

sh: Use struct syscore_ops instead of sysdevs

2011-03-23T09:57:37+00:00

Convert the SuperH clocks framework and shared interrupt handling
code to using struct syscore_ops instead of a sysdev classes and
sysdevs for power managment.

This reduces the code size significantly and simplifies it.  The
optimizations causing things not to be restored after creating a
hibernation image are removed, but they might lead to undesirable
effects during resume from hibernation (e.g. the clocks would be left
as the boot kernel set them, which might be not the same way as the
hibernated kernel had seen them before the hibernation).

This also is necessary for removing sysdevs from the kernel entirely
in the future.
