Viresh Kumar	b43a7ffbf3	cpufreq: Notify all policy->cpus in cpufreq_notify_transition() ... 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.

Wei Yongjun	3a3656d401	imx6q-cpufreq: fix return value check in imx6q_cpufreq_probe() ... In case of error, the function devm_regulator_get() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().

Shawn Guo	1dd538f072	cpufreq: add imx6q-cpufreq driver ... Add an imx6q-cpufreq driver for Freescale i.MX6Q SoC to handle the hardware specific frequency and voltage scaling requirements. The driver supports module build and is instantiated by the platform device/driver mechanism, so that it will not be instantiated on other platforms, as IMX is built with multiplatform support.
