    [PATCH] yenta TI: turn off interrupts during card power-on #2 · fa912bcb
    Daniel Ritz 提交于
    - 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())
