This series forces MMC, IVA2 and D2D/modem into known reset/idle states so that the OMAP3 can hit full-chip idle. Tested on OMAP3 Beagle, and custom OMAP3 hardware. NOTE: this is similar to the set I posted for the PM branch but this series is rebased onto linux-omap and includes the MMC reset. Kevin Hilman (5): OMAP3: PM: HSMMC: force MMC module reset on boot OMAP3: PM: Force IVA2 into idle during bootup OMAP3: PM: Add D2D clocks and auto-idle setup to PRCM init OMAP3: PM: D2D clockdomain supports SW supervised transitions OMAP3: PM: Ensure modem is reset during PRCM init arch/arm/mach-omap2/clock34xx.h | 37 +++++++++++++- arch/arm/mach-omap2/clockdomains.h | 2 +- arch/arm/mach-omap2/cm-regbits-34xx.h | 14 +++++ arch/arm/mach-omap2/devices.c | 76 +++++++++++++++++++++++++++++ arch/arm/mach-omap2/pm34xx.c | 65 ++++++++++++++++++++++++- arch/arm/plat-omap/include/mach/control.h | 5 ++ 6 files changed, 195 insertions(+), 4 deletions(-)
