This patch series introduces support for Dynamic Voltage and Frequency Scaling (DVFS) for OMAP devices. For detailed design details, refer to DVFS Documentation. Pending Work: 1. OMAP4 support Changes done in this series: 1. Seperated DVFS code from Voltage layer (voltage.c) and introduced DVFS layer in dvfs.c 2. Added support for frequency throttling and frequency locking (by introducing frequency list per device) 3. Added changes in omap cpufreq driver for DVFS support 4. Fixed race condition issues in DVFS layer 5. Added documentation for DVFS framework 5. Addressed comments received on V2 V1: https://patchwork.kernel.org/patch/120132/ V2: https://patchwork.kernel.org/patch/290542/ Contributors to conceptualization of the design include Anand Sawant <sawant@xxxxxx> Benoit Cousson <b-cousson@xxxxxx>, Kevin Hilman <khilman@xxxxxxxxxxxxxxxxxxx>, Paul Wamsley <paul@xxxxxxxxx>, Parthasarathy Basak <p-basak2@xxxxxx> Thara Gopinath <thara@xxxxxx> Vishwanath Sripathy <vishwanath.bs@xxxxxx> This patch series is generated against latest kevin's pm branch and has been tested on ZOOM3 for mpu, iva and core DVFS. Thara Gopinath (6): OMAP: Introduce device specific set rate and get rate in omap_device structure OMAP3: Introduce custom set rate and get rate APIs for scalable OMAP: Disable Smartreflex across DVFS devices OMAP3: Introduce voltage domain info in the hwmod structures. OMAP3: Add voltage dependency table for VDD1. OMAP2PLUS: Enable various options in defconfig Vishwanath BS (7): OMAP: Introduce accessory APIs for DVFS OMAP: Implement Basic DVFS OMAP: Introduce dependent voltage domain support OMAP: Introduce device scale implementation OMAP3: cpufreq driver changes for DVFS support OMAP2PLUS: Replace voltage values with Macros OMAP: Add DVFS Documentation Documentation/arm/OMAP/omap_dvfs | 111 ++++ arch/arm/configs/omap2plus_defconfig | 4 + arch/arm/mach-omap2/Makefile | 2 +- arch/arm/mach-omap2/dvfs.c | 751 +++++++++++++++++++++++++ arch/arm/mach-omap2/omap_hwmod_3xxx_data.c | 3 + arch/arm/mach-omap2/opp3xxx_data.c | 47 +- arch/arm/mach-omap2/opp4xxx_data.c | 13 +- arch/arm/mach-omap2/pm.c | 71 +++ arch/arm/mach-omap2/voltage.c | 159 ++---- arch/arm/plat-omap/cpu-omap.c | 35 +- arch/arm/plat-omap/include/plat/dvfs.h | 34 ++ arch/arm/plat-omap/include/plat/omap_device.h | 9 + arch/arm/plat-omap/include/plat/voltage.h | 148 +++++ arch/arm/plat-omap/omap_device.c | 58 ++ 14 files changed, 1293 insertions(+), 152 deletions(-) create mode 100644 Documentation/arm/OMAP/omap_dvfs create mode 100644 arch/arm/mach-omap2/dvfs.c create mode 100644 arch/arm/plat-omap/include/plat/dvfs.h -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
