Hi, this is question mainly to @nokia.com kernel people familiar with 770 and N800 MMC code and/or OMAP1 vs OMAP2 power management (like those ones who fixed bug http://bugs.maemo.org/show_bug.cgi?id=1204#c120)
Is the MMC_POWER_STANDBY feature implemented in OMAP MMC driver for latest N800 2.6.18 kernel relevant to 770 hardware? Does omap1710 lower MMC slot power in sleep (when all clocks are off) too so this is needed for high capacity cards? Recently I have backported MMC code from N800 2.6.18 kernel to allow SDHC cards to be used in 770 but I don't know whether I should let the code which waits for the card before turning off MMC clock in or not. And while we are are at it, here is second question that bugs me for long time. Does 770 hardware allow to give MMCmobile cards 1.8 volts? From the schematics floating on the net it looks like OMAP uses 1.8 volts but there is LP3928TLX voltage converter [1] [2] between omap and mmc slot which cannot be bypassed in software, is this correct or did I miss something? And third bonus question, is it stupid idea to search for OMAP pins for second MMC interface and connect them directly to dual voltage MMCmobile card capable of running at 1.8 volts and have some chance for this to actually work?
