This patch series introduces Forward Body-Bias (FBB), which is one technique possible using the Adaptive Body-Bias (ABB) LDO. FBB boosts voltage on VDD1 PMOS back gates which helps cold devices with weak silicon characteristics sustain voltage at high OPPs. All OMAP devices built on the 45nm process have ABB as a part of SmartReflex2. This patchset introduces it for OMAP 3630 and OMAP 4 will make use of ABB in the future. Patch series is based on pm-wip-sr and tested on Zoom3. Please note that the final patch in the series is a total hack and only meant for those wishing to test this new feature. arch/arm/mach-omap2/cpufreq34xx.c | 8 +- arch/arm/mach-omap2/prm-regbits-34xx.h | 22 +++++ arch/arm/mach-omap2/prm.h | 6 ++ arch/arm/mach-omap2/voltage.c | 130 ++++++++++++++++++++++++++++- arch/arm/plat-omap/include/plat/control.h | 4 + 5 files changed, 163 insertions(+), 7 deletions(-) -- 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
