PM / OPP: Move opp core to its own directory OPP code is expanding and is already present in multiple directories (cpufreq and power). Lets move it to its own directory, to manage it better. This also moves/renames the cpufreq_opp file to cpu.c, as it will contain helpers for cpu device. Its not just about cpufreq, other frameworks can use OPPs as well.

PM / OPP: Move CONFIG_OF dependent code in a separate file Recently, a few issues were noticed in the code where CONFIG_OF wasn't consistently used for many routines. The core file is big enough now and ifdef hackery makes it less readable. Move OF-specific code to another file and compile that only if CONFIG_OF is enabled. Compile-tested: - For ARM (exynos) with CONFIG_OF enabled - For X86 with CONFIG_OF disabled (have to enable CONFIG_PM_OPP separately) No functional changes.

PM / OPP: Add debugfs support This patch adds debugfs support to OPP layer to export OPPs and their properties for all the devices. This creates a top level directory: /sys/kernel/debug/opp and then device specific directories (based on device names) inside it. For example: 'cpu0', 'cpu1', etc.. If multiple devices share the OPP table, then the real directory is created only for the first device. For all others, links are created to the real directory. Inside the device specific directory, a separate directory is created for each OPP. And within that files per opp property.

PM / OPP: Add ti-opp-supply driver Introduce a ti-opp-supply driver that will use new multiple regulator support that is part of the OPP core This is needed on TI platforms like DRA7/AM57 in order to control both CPU regulator and Adaptive Body Bias (ABB) regulator. These regulators must be scaled in sequence during an OPP transition depending on whether or not the frequency is being scaled up or down. This driver also implements AVS Class0 for these parts by looking up the required values from registers in the SoC and programming adjusted optimal voltage values for each OPP.
