	a possible deadlock.

2001-12-07  Damian Gruszka  <damian.gruszka@VisionSystems.de>

2001-12-07  Tim Waugh  <twaugh@redhat.com>

	* parport_pc.c (dmaval): Don't use DMA by default.  It seems to be

	behaviour.

2001-12-07  Tim Waugh  <twaugh@redhat.com>

	* daisy.c (DEBUG): Undefine.

2001-12-06  Tim Waugh  <twaugh@redhat.com>

	* ieee1284_ops.c (parport_ieee1284_ecp_read_data): Mask off
	PARPORT_CONTROL_AUTOFD as well.  Bug spotted by Joe
	<joeja@mindspring.com>.

2001-12-03  Rich Liu  <Rich.Liu@ite.com.tw>

	* parport_pc.c (sio_ite_8872_probe): ITE8873 is a single-port
	serial board, not a serial+parallel.

2001-10-26  Tim Waugh  <twaugh@redhat.com>

	* parport_pc.c (parport_irq_probe): When ECR programmable IRQ
	support fails, generate interrupts using the FIFO even if we don't
	want to use the FIFO for real data transfers.
	(parport_pc_probe_port): Display the ECR address if we have an
	ECR, not just if we will use the FIFO.

2001-10-24  Dave Strauss  <D.Strauss@motorola.com>

	* parport_pc.c (parport_pc_compat_write_block_pio,

2001-10-08  Philip Blundell  <philb@gnu.org>

	* parport_pc.c: New modular parameter verbose_logging.

       * parport_pc.c (parport_pc_epp_read_data): added support for
       reading from a w91284pic peripheral, flag is PARPORT_W91284PIC.

2001-05-07  Fred Barnes  <frmb2@ukc.ac.uk>
 
 	* parport_pc.c (parport_pc_epp_read_data,

	change.

	* parport_pc.c: Cut down the size quite a bit (more than 4k off
	the object, about 1k off the zImage) for the older non-PCI
	machines which are typically resource starved anyway...

2001-03-26  R Horn  <rjh@world.std.com>

	* parport_pc.c: Some commentary changes.

2001-04-19  Tim Waugh  <twaugh@redhat.com>

	* parport_pc.c (parport_pc_probe_port): Remove __devinit
	attribute.  Export unconditionally.

2001-04-14  Jeff Garzik  <jgarzik@pobox.com>

	Merged:  2001-03-30  Tim Waugh  <twaugh@redhat.com>

        * drivers/parport/parport_pc.c: Make Via SuperIO chipsets behave
        like everything else with respect to irq= and dma= parameters.

2001-04-08  Tim Waugh  <twaugh@redhat.com>

      * parport_pc.c (parport_pc_save_state): Read from the soft copy of
      the control port.
      (parport_pc_restore_state): Update the soft copy of the control
      port.

2001-03-26  Tim Waugh  <twaugh@redhat.com>

	* share.c (parport_find_number, parport_find_base): Trigger
	a lowlevel driver load if there are no ports yet.

2001-03-26  Tim Waugh  <twaugh@redhat.com>

	* parport_pc.c (parport_ECP_supported): Remove the IRQ conflict
	check since it seems totally unreliable.

2001-03-02  Tim Waugh  <twaugh@redhat.com>

	* ieee1284_ops.c (parport_ieee1284_read_nibble): Reset nAutoFd
	on timeout.  Matches 2.2.x behaviour.

2001-03-02  Andrew Morton <andrewm@uow.edu.au>

	* parport_pc.c (registered_parport): New static variable.
	(parport_pc_find_ports): Set it when we register PCI driver.
	(init_module): Unregister PCI driver if necessary when we
	fail.

2001-03-02  Tim Waugh  <twaugh@redhat.com>

	* ieee1284_ops.c (parport_ieee1284_write_compat): Don't use
	down_trylock to reset the IRQ count.  Don't even use sema_init,
	because it's not even necessary to reset the count.  I can't
	remember why we ever did.

2001-01-04  Peter Osterlund  <peter.osterlund@mailbox.swipnet.se>

	* ieee1284.c (parport_negotiate): Fix missing printk argument.

2001-01-03  Paul Schleger  <Paul.Schleger@t-online.de>
