Log:
What:
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.
