> Subject: [PATCH 00/13] OMAP: Basic DVFS Framework
>
> 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/

> 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
