o ToPIC is happy with two cards now, even when the two cards are modems. o Fix (all?) hangs on boot when power is applied to the card. I suspect that this will make the Ricoh bridges happier and also make a lot of VAIO owners happy (confirm to me in private email please :-). o All Cardbus bridges should now support 3.3V, X.XV and Y.YV cards, to the extent that the underlying hardware supports such cards. (X.X and Y.Y haven't been assigned values yet :-). o Better 3.3V support for Ricoh ISA bridges. How: o Don't mess with the power register when scanning the cards. It is unnecessary and causes BADVcc conditions on many chipsets. These in turn can cause an interrupt storm. o Make pcic_disable reset the slot's voltage. o Move initializing voltage for the slot until after it has been disabled. o Fix a lot of issues with the pcic_cardbus_power routine. We now properly enable the card and take it out of reset after a power change. o When detecting the card's voltage, if we're in a BadVcc state, direct the bridge to rescan the card for what it supports. (we might need to in the future set the power register to 0 before doing this). o Don't preserve CLKSTOP. need to revisit this. o Better support for Ricoh ISA bridges for 3.3V cards. o Don't write to PCIC_POWER directly as offten, but instead go through the pcic_power interface. o All cardbus bridges now default to use cardbus power control. o Add misc register definitions. o remove some (now) bogus comments. Extra Special Thanks To: Scott Lamber for his kind and generous loan of a Toshiba laptop with a ToPIC 100 in it for my use.
