Hello, something happened during the last cycle and an old version of the devfreq driver was merged. This thread contains patches that bring it up to date to the last submitted version and also incorporates the feedback that that version received, plus some other small fixes and improvements that came up during rebase and testing. These patches implement support for setting the rate of the EMC clock based on stats collected from the ACTMON, a piece of hw in the Tegra124 that counts memory accesses (among others). It depends on the following in-flight patches: * EMC driver: http://thread.gmane.org/gmane.linux.kernel/1907035 * CPUFreq driver: http://thread.gmane.org/gmane.linux.kernel/1897078 I have pushed a branch here for testing: http://cgit.collabora.com/git/user/tomeu/linux.git/log/?h=actmon-v6 Regards, Tomeu Tomeu Vizoso (8): of: Add binding for NVIDIA Tegra ACTMON node PM / devfreq: tegra: Update to v5 of the submitted patches clk: tegra: Have EMC clock implement determine_rate() PM / devfreq: tegra: Use clock rate constraints PM / devfreq: tegra: remove operating-points PM / devfreq: tegra: Set drvdata before enabling the irq PM / devfreq: tegra: Enable interrupts after resuming the devfreq monitor ARM: tegra: Add Tegra124 ACTMON support .../devicetree/bindings/arm/tegra/actmon.txt | 28 ++ arch/arm/boot/dts/tegra124.dtsi | 11 + drivers/clk/tegra/clk-emc.c | 19 +- drivers/devfreq/tegra-devfreq.c | 480 +++++++++++---------- 4 files changed, 316 insertions(+), 222 deletions(-) create mode 100644 Documentation/devicetree/bindings/arm/tegra/actmon.txt -- 2.1.0 -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
