Wysocki" , linux-samsung-soc@vger.kernel.org, linux-arm-kernel@lists.infradead.org, Kukjin Kim , Thomas Abraham , cpufreq@vger.kernel.org, Inderpal Singh , Viresh Kumar , Sylwester Nawrocki , Russell King - ARM Linux List-Id: linux-pm@vger.kernel.org Submitting the V6 version of exynos5440 cpufreq driver. This patchset addresses all the coding and design concerns raised especially by Viresh. Changes in V6: * Used cpufreq post-change notifier call back in case of failure as pointed by Viresh. * Called cpufreq_frequency_table_cpuinfo before calling cpufreq_frequency_table_get_attr as pointed by Viresh. * Used modified API cpufreq_notify_transition. Changes in V5: * Removed the unnecessary DT look up entry from mach-exynos5-dt.c. * Fixed all coding and comments issue raised by Viresh. Changes in V4: * Added dev_err logs instead of pr_err. * Used the devm_ioremap_resource API. * Implemented several coding guidelines and minor error comments from Sylwester, Russell and Viresh. Changes in V3: * Converted the driver to probe based as suggested by Viresh. This is also beneficial for multiplatform kernel. * Other coding guidelines related changes. * Moved the DT node outside cpu0 node as the driver is now a platform driver. Changes in V2: * Added OPP library support to parse DT parameters. * Removed a hack to handle interrupts in bootup. * Implemented other review comments from Viresh and Inder. All these patches are dependent on Thomas Abraham common clock patches.
