- DESCRIPTION
- 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.
-
- 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.
-
- An i82365-compatible controller normally sits at the IO
- addresses 0x3e0-0x3e1. Two controllers can cooperate to
- share the same IO ports, supporting a total of four sock¡
- ets. A second pair of controllers can be located at
- 0x3e2-0x3e3. Probing at this position is controlled by
- the extra_sockets parameter. The driver will support a
- maximum of eight sockets.
-
-
- PARAMETERS
- 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.
-
- 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 sockets, or stop after checking for
- four sockets. The default is 0 (stop at four sock¡
- ets). Systems with two independent PCMCIA con¡
- trollers (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 automati¡
- cally 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.
-
- 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.
-
-
- Options for CardBus controllers
- 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_mem_base=n
- Sets the base address to use for memory mapping
- CardBus registers, if not set by the PCI BIOS. The
- default is 0x68000000.
-
- cb_bus_base=n
- Specifies that PCI bus numbers for CardBus busses
- should be renumbered starting with this value. By
- default, bus values that are uninitialized at boot
- time will be numbered starting with bus 0x20.
-
- cb_bus_step=n
- Specifies the number of bus slots to reserve for
- secondary PCI busses, for each CardBus socket, when
- busses are renumbered. The default is 2.
-
- cb_write_post=n
- A flag indicating if write posting (a performance
- feature) should be enabled. The default is 1
- (true), except on 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 0 (false).
-
- pci_int=n
- Specifies that functional interrupts for IO cards
- should be routed to PCI interrupts, for CardBus
- controllers. The default is 0 (false).
-
-
- Options specific for Cirrus controllers
- 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.
-
-
- Options specific for Ricoh CardBus controllers
- 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.
-
-
- Options specific for Vadem controllers
- 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 cer¡
- tain socket signals for driving a socket connected
- via a cable.

- Options specific for TI CardBus controllers
- 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.
-
- has_clkrun=n
- A flag indicating if the controller is wired for
- PCI CLKRUN support. The default is to read the
- current setting from the controller.
-
- clkrun_sel=n
- A flag indicating if the CLKRUN signal is wired to
- the ISA interrupt 12 pin, as opposed to ISA inter¡
- rupt 10. The default is to read the current set¡
- ting from the controller.
-
- irq_mode=n
- Selects the interrupt routing method. A value of 1
- selects ISA interrupt routing; 2 selects ISA inter¡
- rupt routing via an external serial interrupt con¡
- troller; and 3 selects serial routing for both PCI
- and ISA interrupts. The default is to use whatever
- routing method is already active, or ISA routing if
- no method is enabled.
