This is the low-level driver for the Intel i82365sl PCMCIA
host controller, and many derivative controllers. It also
implements the Intel "Yenta" register specification for
CardBus bridges. Common clones of the i82365sl include
controllers made by Cirrus Logic, IBM, O2Micro, Omega
Micro, Ricoh, SMC, Texas Instruments, Toshiba, Vadem, and
VLSI. The overwhelming majority of current PCMCIA con
trollers, and all CardBus bridges, are register compatible
with the i82365sl. This driver is used by Card Services
for configuring the host controller, and for monitoring
card status change events.
An ISA i82365-compatible controller normally sits at the
IO addresses 0x3e0-0x3e1. Two ISA controllers can cooper
ate to share the same IO ports, supporting a total of four
sockets. A second pair of controllers can be located at
0x3e2-0x3e3. Probing at this position is controlled by
the extra_sockets parameter. This only affects ISA
bridges: the PCI bridge probe handles multiple controllers
automatically. The driver will support a maximum of eight
sockets.
pc_debug=n
Selects the PCMCIA debugging level. This parameter
is only available if the module is compiled with
debugging enabled. A non-zero value enables debug
ging.
i365_base=n
Sets the base I/O port address of the i82365sl
chip. The default is 0x3e0. Applies only to ISA-
to-PCMCIA bridges.
ignore=n
Causes the driver to ignore a single socket. Sock
ets are numbered starting at 0. The socket will be
left in whatever state it was already in, so it can
be used for cards with point enablers that do not
cooperate with Card Services.
extra_sockets=n
A flag indicating if the driver should probe for as
many as eight ISA sockets, or stop after checking
for four sockets. The default is 0 (stop at four
sockets). Systems with two independent ISA-to-PCM
CIA controllers (say, one internal and one in a
docking station) may require this flag to be set,
even though they have a total of only four sockets.
If this flag is set, then poll_interval will auto
matically be enabled.
do_scan=n
This flag specifies that all free interrupts should
be tested to see if they can be triggered by the
PCMCIA controller. The default is 1 (true).
irq_list=i,j,...
Specifies the set of interrupts that may be allo
cated by this driver, if they are otherwise avail
able. The default list is 3, 4, 5, 7, 9, 10, 11,
12, 14, and 15.
cs_irq=n
Sets the interrupt line to use for monitoring card
status changes. The default is 0, which means pick
the highest-numbered legal interrupt not already in
use. Legal values are 15, 14, 12, 11, 10, 9, 7, 5,
4, and 3.
poll_interval=n
Sets the card status polling delay, in 1/100 second
increments. If this parameter is set, card status
interrupts will be disabled. A reasonable value is
100. Polling only affects detection of card insert
and eject events.
cycle_time=n
Sets the length of a host bus cycle, in nanosec
onds. The default is 210 ns, corresponding to a
standard 4.77 MHz clock.
do_pci_probe=n
This flag indicates if the PCI bus should be probed
for PCI-to-PCMCIA and/or PCI-to-CardBus bridges.
The default is 1 (true).
cb_write_post=n
A flag indicating if write posting (a performance
feature) should be enabled. The default is 1
(true), except on certain TI 1130 bridges.
pci_csc=n
Specifies that card status change interrupts should
be routed to PCI interrupts, for CardBus con
trollers. The default is 1 (true).
pci_int=n
Specifies that functional interrupts for IO cards
should be routed to PCI interrupts, for CardBus
controllers. The default is 1 (true), except on
systems that require use of PCI interrupts.
pci_irq_list=i,j,...
The Linux kernel sometimes cannot deduce the PCI
interrupt assignments for CardBus sockets. If this
information can be determined some other way, it
can be entered here. The Nth socket will get the
Nth interrupt number from the list.
When the i82365 driver is loaded, it will try to determine
what interrupts can safely be allocated for use by PCMCIA
devices. Cirrus controllers support some optional fea
tures that interfere with the use of certain interrupt
lines. Cirrus chips also lack the functionality needed to
detect whether or not an interrupt can be used. The
has_dma, has_ring, and has_led options are used to specify
if these features are implemented.
has_dma=n
A flag indicating if the controller has DMA sup
port.
has_led=n
A flag indicating if the controller is wired for a
disk status LED. This is set by default.
has_ring=n
A flag indicating if the controller's "ring indi
cate" signal is implemented. This is set by
default.
freq_bypass=n
A flag indicating that the controller should be set
up in "frequency bypass" mode. This disables the
normal 7/4 clock multiplier, and slows down all
PCMCIA bus access, for systems with fast system
clocks.
setup_time=n
Sets the bus setup time, in internal clock cycles.
The default is 1.
cmd_time=n
Sets the bus command time, in internal clock
cycles. The default is 6.
recov_time=n
Sets the bus recovery time, in internal clock
cycles. The default is 0.
wakeup=n
A flag indicating if the probe function should
attempt to wake up a suspended controller chip.
The default is 0.
fast_pci=n
A flag for the CL6729 PCI controller, indicating
that the PCI bus speed exceeds 25 MHz.
irq_mode=n
Selects the interrupt routing method. A value of 1
selects ISA interrupt routing, and 2 selects inter
rupt routing via an external serial interrupt con
troller. The default is to use whatever routing
method is already enabled.
setup_time=n
Sets the bus setup time, in internal clock cycles.
The default is 3.
cmd_time=n
Sets the bus command time, in internal clock
cycles. The default is 6.
hold_time=n
Sets the bus hold time, in internal clock cycles.
The default is 1.
async_clock=n
This flag specifies that PCMCIA bus cycles should
be clocked asynchronously from host bus cycles. It
effectively adds a wait state to some operations.
cable_mode=n
For the VG469, this flag adjusts certain socket
signals for driving a socket connected via a cable.
Normally, a system's BIOS will configure these options
appropriately, so all these options default to leaving
these features configured the way the driver finds them.
has_ring=n
A flag indicating if the controller is wired for
"ring indicate". The default is to read the cur
rent setting from the controller.
irq_mode=n
Selects the interrupt routing method. A value of 0
selects only PCI interrupts; 1 selects ISA inter
rupt routing; 2 selects ISA interrupt routing via
an external serial interrupt controller; and 3
selects serial routing for both PCI and ISA inter
rupts. The default is to use whatever routing
method is already active, or ISA routing if no
method is enabled.
p2cclk=n
A flag, indicating if the P2CCLK pin should be con
figured as an input (0) or an output (1). This
signal is used for communicating with a socket
power controller; if set incorrectly, the bridge
will be unable to power up cards. The default is
to use the BIOS setting.
