cpufreq: dbx500: Round to closest available freq

2013-04-11T21:23:57+00:00

When reading the cpu speed, round it to the closest available
frequency from the table.

cpufreq: drivers: don't check range of target freq in .target()

2013-04-02T13:26:32+00:00

Cpufreq core checks the range of target_freq before calling driver->target() and
so we don't need to do it again.

Remove it.

cpufreq: Notify all policy->cpus in cpufreq_notify_transition()

2013-04-02T13:24:00+00:00

policy->cpus contains all online cpus that have single shared clock line. And
their frequencies are always updated together.

Many SMP system's cpufreq drivers take care of this in individual drivers but
the best place for this code is in cpufreq core.

This patch modifies cpufreq_notify_transition() to notify frequency change for
all cpus in policy->cpus and hence updates all users of this API.

cpufreq: db8500: set CPUFREQ_CONST_LOOPS

2013-01-07T15:03:43+00:00

As ux500 is being converted to timer based delay loops, and the timer
used is not depending on CPUs clock frequency, set cpufreq_driver flag
CPUFREQ_CONST_LOOPS to prevent cpufreq rescaling loops_for_jiffies.

cpufreq: Give driver used for dbx500 family a more generic name

2013-01-07T15:03:01+00:00

This driver doesn't only handle cpufreq functionality for the
db8500 anymore. There are new variants which rely on it too.
Let's make the name a bit more generic.
