 Interface /proc/isapnp
 ======================
 
-Read commands:
---------------
+The interface has been removed. See pnp.txt for more details.
 
-No comment.
-
-Write commands:
----------------
-
-With the write interface you can activate or modify the configuration of
-ISA Plug & Play devices.  It is mainly useful for drivers which have not
-been rewritten to use the ISA Plug & Play kernel support yet.
-
-card <idx> <vendor>	- select PnP device by vendor identification
-csn <CSN>		- select PnP device by CSN
-dev <idx> <logdev>	- select logical device
-auto			- run autoconfigure
-activate		- activate logical device
-deactivate		- deactivate logical device
-port <idx> <value>	- set port 0-7 to value
-irq <idx> <value>	- set IRQ 0-1 to value
-dma <idx> <value>	- set DMA 0-1 to value
-memory <idx> <value>	- set memory 0-3 to value
-poke <reg> <value>	- poke configuration byte to selected register
-pokew <reg> <value>	- poke configuration word to selected register
-poked <reg> <value>	- poke configuration dword to selected register
-allow_dma0 <value>	- allow dma channel 0 during auto activation: 0=off, 1=on
-
-Explanation:
-	- variable <idx> begins with zero
-	- variable <CSN> begins with one
-	- <vendor> is in the standard format 'ABC1234'
-	- <logdev> is in the standard format 'ABC1234'

-                                        struct pci_bus *from);
-
-This function finds an ISA PnP card.  For the vendor argument, the
-ISAPNP_VENDOR(a,b,c) macro should be used, where a,b,c are characters or
-integers.  For the device argument the ISAPNP_DEVICE(x) macro should be
-used, where x is an integer value.  Both vendor and device arguments
-can be taken from contents of the /proc/isapnp file.
-
-extern struct pci_dev *isapnp_find_dev(struct pci_bus *card,

-
-This function finds an ISA PnP device. If card is NULL, then the global
-search mode is used (all devices are used for the searching).  Otherwise
-only devices which belong to the specified card are checked.  For the
-function number the ISAPNP_FUNCTION(x) macro can be used; it works
-similarly to the ISAPNP_DEVICE(x) macro.

-ISA PnP configuration
-=====================
-
-There are two ways in which the ISA PnP interface can be used.
-
-First way: low-level
---------------------
-
-All ISA PNP configuration registers are accessible via the low-level
-isapnp_(read|write)_(byte|word|dword) functions.
-
-The function isapnp_cfg_begin() must be called before any lowlevel function.
-The function isapnp_cfg_end() must be always called after configuration
-otherwise the access to the ISA PnP configuration functions will be blocked.
-
-Second way: auto-configuration
-------------------------------
-
-This feature gives to the driver the real power of the ISA PnP driver.
-The function dev->prepare() initializes the resource members in the device
-structure.  This structure contains all resources set to auto configuration
-values after the initialization.  The device driver may modify some resources
-to skip the auto configuration for a given resource.
-
-Once the device structure contains all requested resource values, the function
-dev->activate() must be called to assign free resources to resource members
-with the auto configuration value.
-
-Function dev->activate() does:
-   - resources with the auto configuration value are configured
-   - the auto configuration is created using ISA PnP resource map
-   - the function writes configuration to ISA PnP configuration registers
-   - the function returns to the caller actual used resources
-
-When the device driver is removed, function dev->deactivate() has to be
-called to free all assigned resources.
-
-Example (game port initialization)
-==================================
-
-/*** initialization ***/
-
-	struct pci_dev *dev;
-
-	/* find the first game port, use standard PnP IDs */
-	dev = isapnp_find_dev(NULL,
-			      ISAPNP_VENDOR('P','N','P'),
-			      ISAPNP_FUNCTION(0xb02f),
-			      NULL);
-	if (!dev)
-		return -ENODEV;
-	if (dev->active)
-		return -EBUSY;
-	if (dev->prepare(dev)<0)
-		return -EAGAIN;
-	if (!(dev->resource[0].flags & IORESOURCE_IO))
-		return -ENODEV;
-	if (!dev->ro) {
-		/* override resource */
-		if (user_port != USER_PORT_AUTO_VALUE)
-			isapnp_resource_change(&dev->resource[0], user_port, 1);
-	}
-	if (dev->activate(dev)<0) {
-		printk("isapnp configure failed (out of resources?)\n");
-		return -ENOMEM;
-	}
-	user_port = dev->resource[0].start;		/* get real port */
-
-/*** deactivation ***/
-
-	/* to deactivate use: */
- 	if (dev)
- 		dev->deactivate(dev);
