[PATCH v3 0/4] PXA cpufreq conversion to clock API

[PATCH v3 0/4] PXA cpufreq conversion to clock API

[Robert Jarzmik]

Hi,

This serie is a preparation to shift the cpufreq of pxa2xx platforms to clocks
API, next iteration.

The first 3 patches are review and merge material :
 - patch 1/4 for Viresh and Rafael
 - patches 2/4 and 3/4 for me

The 4th on is for review but not merge, as the clock changes must be fully
reviewed and go in first as a prequisite

Since previous iteration, 2 and 3 were amended per Viresh's suggestion.

Robert Jarzmik (4):
  cpufreq: pxa: use generic platdev driver for device-tree
  ARM: dts: pxa: add pxa25x cpu operating points
  ARM: dts: pxa: add pxa27x cpu operating points
  cpufreq: pxa: convert to clock API

[PATCH v3 1/4] cpufreq: pxa: use generic platdev driver for device-tree

[Robert Jarzmik]

For device-tree based pxa25x and pxa27x platforms, cpufreq-dt driver is
doing the job as well as pxa2xx-cpufreq, so add these platforms to the
compatibility list.

This won't work for legacy non device-tree platforms where
pxa2xx-cpufreq is still required.

[PATCH v3 4/4] cpufreq: pxa: convert to clock API

[Robert Jarzmik]

As the clock settings have been introduced into the clock pxa drivers,
which are now available to change the CPU clock by themselves, remove
the clock handling from this driver, and rely on pxa clock drivers.

Ok, thanks Viresh.

Would you or Rafael take patch 1/4 "cpufreq: pxa: use generic platdev driver for
device-tree" through your tree please ?

I'll take patches 2 and 3 through my tree, and we'll wait for clock patches to
hit clock tree before I ask patch 4/4 to be applied.

Cheers.

Rafael is the one who applies the patches.
