It also: - enhances arm_big_little[_dt] driver with CPU cluster regulator support - adds CPU clock configuration data and CPU operating points setup for Exynos542x/5800 - adds CPU cluster regulator supplies for Exynos542x/5800 boards This patch series has been tested on Exynos5422 based ODROID-XU3 Lite board. Please note that this is not a final version of the patchset. I just wanted to push out current work-in-progress patches that integrate changes from Anand, Ben and me. TODO: - porting the Exynos542x/5800 support over cpufreq-dt Depends on: - next-20151124 branch of linux-next kernel tree Changes since v2: - ported over next-20151124 branch - integrated missing CLK_RECALC_NEW_RATES flags fix to patch #3 (from Anand Moon) - added regulator supply properties for ODROID-XU3 Lite and ODROID-XU4 in patch #2 - ported CPU OPPs to operating-points-v2 (from Ben Gamari) - added "ARM: dts: Exynos5422: fix OPP tables" patch (from Ben Gamari) - added "cpufreq: arm-big-little: accept operating-points-v2 nodes" patch (from Ben Gamari) - renamed OPP nodes as opp@<opp-hz> Changes since v1: - added CPU cluster regulator supply properties to exynos5420-arndale-octa.dts, exynos5420-peach-pit.dts, exynos5420-smdk5420.dts and exynos5800-peach-pi.dts Changes over Thomas' original v12 code: - split Exynos5420 and Exynos5800 support - moved E5420_[EGL,KFC]_DIV0() macros to clk-exynos5420.c - disabled cpufreq if big.LITTLE switcher support is enabled - enhanced arm_big_little[_dt] driver with CPU cluster regulator support - fixed CPU clock configuration data for Exynos5800 - fixed CPU operating points setup for Exynos5800 - added CPU cluster regulator supplies for ODROID-XU3 board Best regards, -- Bartlomiej Zolnierkiewicz Samsung R&D Institute Poland Samsung Electronics Bartlomiej Zolnierkiewicz (4): cpufreq: arm_big_little: add cluster regulator support ARM: dts: Exynos5420/5800: add cluster regulator supply properties clk: samsung: exynos5800: fix cpu clock configuration data ARM: dts: Exynos5800: fix CPU OPP Ben Gamari (2): ARM: dts: Exynos5422: fix OPP tables cpufreq: arm-big-little: accept operating-points-v2 nodes Thomas Abraham (4): clk: samsung: exynos5420: add cpu clock configuration data and instantiate cpu clock ARM: dts: Exynos5420: add CPU OPP and regulator supply property ARM: Exynos: use generic cpufreq driver for Exynos5420 ARM: Exynos: use generic cpufreq driver for Exynos5800 .../bindings/cpufreq/arm_big_little_dt.txt | 4 + arch/arm/boot/dts/exynos5420-arndale-octa.dts | 8 + arch/arm/boot/dts/exynos5420-peach-pit.dts | 8 + arch/arm/boot/dts/exynos5420-smdk5420.dts | 8 + arch/arm/boot/dts/exynos5420.dtsi | 122 ++++++++++++++ arch/arm/boot/dts/exynos5422-cpus.dtsi | 10 ++ arch/arm/boot/dts/exynos5422-odroidxu3-lite.dts | 8 + arch/arm/boot/dts/exynos5422-odroidxu3.dts | 8 + arch/arm/boot/dts/exynos5422-odroidxu4.dts | 8 + arch/arm/boot/dts/exynos5800-peach-pi.dts | 8 + arch/arm/boot/dts/exynos5800.dtsi | 165 +++++++++++++++++++ arch/arm/mach-exynos/exynos.c | 8 + drivers/clk/samsung/clk-exynos5420.c | 88 ++++++++++- drivers/cpufreq/arm_big_little.c | 175 +++++++++++++++++---- drivers/cpufreq/arm_big_little_dt.c | 12 +- include/dt-bindings/clock/exynos5420.h | 2 + 16 files changed, 608 insertions(+), 34 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
