      cpufreq: Avoid calling cpufreq_verify_current_freq() from handle_update() · 70a59fde
      由 Viresh Kumar 提交于 
      On some occasions cpufreq_verify_current_freq() schedules a work whose
callback is handle_update(), which further calls cpufreq_update_policy()
which may end up calling cpufreq_verify_current_freq() again.

On the other hand, when cpufreq_update_policy() is called from
handle_update(), the pointer to the cpufreq policy is already
available, but cpufreq_cpu_acquire() is still called to get it in
cpufreq_update_policy(), which should be avoided as well.

To fix these issues, create a new helper, refresh_frequency_limits(),
and make both handle_update() call it cpufreq_update_policy().

      cpufreq: Consolidate cpufreq_update_current_freq() and __cpufreq_get() · 5980752e
      由 Viresh Kumar 提交于 
      Their implementations are quite similar, so modify
cpufreq_update_current_freq() somewhat and call it from
__cpufreq_get().

Also rename cpufreq_update_current_freq() to
cpufreq_verify_current_freq(), as that's what it is doing.

      cpufreq: Don't skip frequency validation for has_target() drivers · 98015228
      由 Viresh Kumar 提交于 
      CPUFREQ_CONST_LOOPS was introduced in a very old commit from pre-2.6
kernel release by commit 6a4a93f9c0d5 ("[CPUFREQ] Fix 'out of sync'
issue").

Basically, that commit does two things:

 - It adds the frequency verification code (which is quite similar to
   what we have today as well).

 - And it sets the CPUFREQ_CONST_LOOPS flag only for setpolicy drivers,
   rightly so based on the code we had then. The idea was to avoid
   frequency validation for setpolicy drivers as the cpufreq core doesn't
   know what frequency the hardware is running at and so no point in
   doing frequency verification.

The problem happened when we started to use the same CPUFREQ_CONST_LOOPS
flag for constant loops-per-jiffy thing as well and many has_target()
drivers started using the same flag and unknowingly skipped the
verification of frequency. There is no logical reason behind skipping
frequency validation because of the presence of CPUFREQ_CONST_LOOPS
flag otherwise.

Fix this issue by skipping frequency validation only for setpolicy
drivers and always doing it for has_target() drivers irrespective of
the presence or absence of CPUFREQ_CONST_LOOPS flag.

cpufreq_notify_transition() is only called for has_target() type driver
and not for set_policy type, and the check is simply redundant. Remove
it as well.

Also remove () around freq comparison statement as they aren't required
and checkpatch also warns for them.

      clk: Remove io.h from clk-provider.h · 62e59c4e
      由 Stephen Boyd 提交于 
      Now that we've gotten rid of clk_readl() we can remove io.h from the
clk-provider header and push out the io.h include to any code that isn't
already including the io.h header but using things like readl/writel,
etc.

Found with this grep:

I also reordered a couple includes when they weren't alphabetical and
removed clk.h from kona, replacing it with clk-provider.h because
that driver doesn't use clk consumer APIs.
