Hello, I am running the l-o (55936cdfaaf11ac352b56bc58e42d6661e65ee13) with following: - ARM: OMAP3: Add OMAP3_HAS_IVA_REGS feature - ARM: OMAP3: Use OMAP3_HAS_IVA_REGS with OMAP3503 - OMAPDSS: PM runtime fixes for 3.5-rc Using omap2plus_defconfig. - Minus EHCI - Minus ADS7846 - Minus SMP - Plus initramfs Running on Gumstix Overo Earth (OMP3503). My problem is that while suspend (with the above patches) seems to function the debug counters for DSS do not indicate retention or off mode.

After building it (and PANEL_GENERIC) into kernel the situation does not change. Strangely the core domain is able to go to retention (or off if enabled) even though DSS isn't. Suspend _seems_ to work but I only see a meager 10mA reduction (from 80mA to 70mA) in the current to the gumstix so I'm suspicious. Can anyone shed any light on this? - Juha -- 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
