cpufreq: Adjust includes to remove of_device.h Now that of_cpu_device_node_get() is defined in of.h, of_device.h is just implicitly including other includes, and is no longer needed. Adjust the include files with what was implicitly included by of_device.h (cpu.h and of.h) and drop including of_device.h. Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Acked-by: Rafael J.

kbuild, cpufreq: tegra124: remove MODULE_LICENSE in non-modules Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

cpufreq: tegra124: Add suspend and resume support This patch adds suspend and resume pm ops for cpufreq driver. PLLP is the safe clock source for CPU during system suspend and resume as PLLP rate is below the CPU Fmax at Vmin. CPUFreq driver suspend switches the CPU clock source to PLLP and disables the DFLL clock. During system resume, warmboot code powers up the CPU with PLLP clock source. So CPUFreq driver resume enabled DFLL clock and switches CPU back to DFLL clock source.

cpufreq: tegra124: do not handle the CPU rail The Tegra124 cpufreq driver has no information to handle the Vdd-CPU rail. So this driver shouldn't handle for the CPU clock switching from DFLL to other PLL clocks. It was designed to work on DFLL clock only, which handle the frequency/voltage scaling in the background. This patch removes the driver dependency of the CPU rail, as well as not allow it to be built as a module and remove the removal function. So it can keep working on DFLL clock.

cpufreq: Add cpufreq driver for Tegra124 Add a new cpufreq driver for Tegra124. Instead of using the PLLX as the CPU clocksource, switch immediately to the DFLL. It allows the use of higher clock rates, and will automatically scale the CPU voltage as well. Besides the CPU clocksource switch, we let the cpufreq-dt driver for all the cpufreq operations. This driver also relies on the DFLL driver to fill the OPP table for the CPU0 device, so that the cpufreq-dt driver knows what frequencies to use.
