Subject: [PATCH v2 0/4] ARM: dts: s5pv210: Enable cpufreq support

This patchset enables cpufreq support using s5pv210-cpufreq driver.

First patch adds missing dmc nodes, which are required by driver.

Second patch is cosmetic, it stops driver from flooding kernel log with
 messages, after every change of freq.

Third patch adds defer probe support for regulators, needed by driver.
It was observed, that those regulators can be no yet initialized, when
 driver is probed, so we should wait till we can get them.

Last patch enables required kernel config options.

Changes from v1:
  - Added Acked-by to one of patches
  - Fix compilation error after changes in driver
  - Reorganize code (so it's smaller), inside patch which logs information
    about defered probe of regulators

Paweł Chmiel (4):
  ARM: dts: s5pv210: Add dmc nodes
  cpufreq: s5pv210: Don't flood kernel log after cpufreq change
  cpufreq: s5pv210: Defer probe if getting regulators fail
  ARM: defconfig: s5pv210: Add cpufreq support
