2017-02-09cpufreq: dt: Don't use generic platdev driver for ti-cpufreq platformsDave Gerlach
Some TI platforms, specifically those in the am33xx, am43xx, dra7xx, and am57xx families of SoCs can make use of the ti-cpufreq driver to selectively enable OPPs based on the exact configuration in use. The ti-cpufreq is given the responsibility of creating the cpufreq-dt platform device when the driver is in use so drop am33xx and dra7xx from the cpufreq-dt-platdev driver so it is not created twice.

2016-11-11cpufreq: pxa: use generic platdev driver for device-treeRobert 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.

2016-09-16cpufreq: ti: Use generic platdev driverDave Gerlach
Now that the cpufreq-dt-platdev is used to create the cpufreq-dt platform device for all OMAP platforms and the platform code that did it before has been removed, add ti,am33xx and ti,dra7xx to the machine list in cpufreq-dt-platdev which had relied on the removed platform code to do this previously.

2016-09-13cpufreq: dt: Support governor tunables per policyViresh Kumar
The cpufreq-dt driver is also used for systems with multiple clock/voltage domains for CPUs, i.e. multiple cpufreq policies in a system. And in such cases the platform users may want to enable "governor tunables per policy". Support that via platform data, as not all users of the driver would want that behavior.

If of_match_node() fails, this init function bails out without calling of_node_put(). Also change of_node_put(of_root) to of_node_put(np); both of them hold the same pointer, but it seems better to call of_node_put() against the node returned by of_find_node_by_path().

2016-04-09cpufreq: dt: Add generic platform-device creation supportViresh Kumar
Multiple platforms are using the generic cpufreq-dt driver now, and all of them are required to create a platform device with name "cpufreq-dt", in order to get the cpufreq-dt probed. Many of them do it from platform code, others have special drivers just to do that. It would be more sensible to do this at a generic place, where all such platform can mark their entries. This patch adds a separate file to get this device created. Currently the compat list of platforms that we support is empty, and will be filled in as and when we move platforms to use it. It always compiles as part of the kernel and so doesn't need a module-exit operation.
