+ The classic in digital I/O. The 8255 appears in Comedi as a single
+ digital I/O subdevice with 24 channels. The channel 0 corresponds
+ to the 8255's port A, bit 0; channel 23 corresponds to port C, bit
+ 7. Direction configuration is done in blocks, with channels 0-7,
+ 8-15, 16-19, and 20-23 making up the 4 blocks. The only 8255 mode
+ supported is mode 0.
+
+ You should enable compilation this driver if you plan to use a board
+ that has an 8255 chip. For multifunction boards, the main driver will
+ configure the 8255 subdevice automatically.
+
+ This driver also works independently with ISA and PCI cards that
+ directly map the 8255 registers to I/O ports, including cards with
+ multiple 8255 chips. To configure the driver for such a card, the
+ option list should be a list of the I/O port bases for each of the
+ 8255 chips. For example,
+
+ comedi_config /dev/comedi0 8255 0x200,0x204,0x208,0x20c
+
+ Note that most PCI 8255 boards do NOT work with this driver, and
+ need a separate driver as a wrapper. For those that do work, the
+ I/O port base address can be found in the output of 'lspci -v'.
+
+ This file contains an exported subdevice for driving an 8255.
+
+ To use this subdevice as part of another driver, you need to
+ set up the subdevice in the attach function of the driver by
+ calling:
+
+ subdev_8255_init(device, subdevice, io_function, iobase)
+
+ device and subdevice are pointers to the device and subdevice
+ structures. io_function will be called to provide the
+ low-level input/output to the device, i.e., actual register
+ access. io_function will be called with the value of iobase
+ as the last parameter. If the 8255 device is mapped as 4
+ consecutive I/O ports, you can use NULL for io_function
+ and the I/O port base for iobase, and an internal function will
+ handle the register access.
+
+ In addition, if the main driver handles interrupts, you can
+ enable commands on the subdevice by calling subdev_8255_init_irq()
+ instead. Then, when you get an interrupt that is likely to be
+ from the 8255, you should call subdev_8255_interrupt(), which
+ will copy the latched value to a Comedi buffer.
