[PATCH] yenta TI: turn off interrupts during card power-on #2
- make boot-up card recognition more reliable (ie. redo interrogation
always if there is no valid 'card inserted' state) (and yes, i saw it
happening on an o2micro controller that both CB_CBARD and CB_16BITCARD
bits were set at the same time)
- also redo interrogation before probing the ISA interrupts. it's safer
to do the probing with the socket in a clean state.
- make card insert detect more reliable. yenta_get_status() now returns
SS_PENDING as long as the card is not completley inserted and one of the
voltage bits is set. also !CB_CBARD doesn't mean CB_16BITCARD. there is
CB_NOTACARD as well, so make an explicit check for CB_16BITCARD.
- for TI bridges: disable IRQs during power-on. in all-serial and tied
interrupt mode the interrupts are always disabled for single-slot
controllers. for two-slot contollers the disabling is only done when the
other slot is empty. to force disabling there is a new module parameter
now: pwr_irqs_off=Y (which is a regression for working setups. that's
why it's an option, only use when required)
- modparm to disable ISA interrupt probing (isa_probe, defaults to on)
- remove unneeded code/cleanups (ie. merge yenta_events() into
yenta_interrupts())
