[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()) Signed-off-by: Daniel Ritz <daniel.ritz@gmx.ch> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
