cpufreq: ti: Add cpufreq driver to determine available OPPs at runtime

2017-02-09T21:57:48+00:00

Some TI SoCs, like those in the AM335x, AM437x, DRA7x, and AM57x families, have different OPPs available for the MPU depending on which specific variant of the SoC is in use. This can be determined through use of the revision and an eFuse register present in the silicon. Introduce a ti-cpufreq driver that can read the aformentioned values and provide them as version matching data to the opp framework. Through this the opp-supported-hw dt binding that is part of the operating-points-v2 table can be used to indicate availability of OPPs for each device. This driver also creates the "cpufreq-dt" platform_device after passing the version matching data to the OPP framework so that the cpufreq-dt handles the actual cpufreq implementation. Even without the necessary data to pass the version matching data the driver will still create this device to maintain backwards compatibility with operating-points v1 tables.

cpufreq: brcmstb-avs-cpufreq: AVS CPUfreq driver for Broadcom STB SoCs

2016-11-01T05:07:37+00:00

This driver supports voltage and frequency scaling on Broadcom STB SoCs using AVS firmware with DFS and DVFS support. Actual frequency or voltage scaling is done exclusively by the AVS firmware. The driver merely provides a standard CPUfreq interface to other kernel components and userland, and instructs the AVS firmware to perform frequency or voltage changes on its behalf.

cpufreq: retire the Integrator cpufreq driver

2016-11-01T05:01:18+00:00

After switching the core module clocks controlling the Integrator clock frequencies to the common clock framework, defining the operating points in the device tree, and activating the generic DT-based CPUfreq driver, we can retire the old Integrator cpufreq driver.

cpufreq: dt: Add generic platform-device creation support

2016-04-08T23:18:42+00:00

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. Signed-off-by: Viresh Kumar Reviewed-by: Krzysztof Kozlowski Signed-off-by: Rafael J. Wysocki
