- * Register map
- *
- * The register map varies slightly depending on the board type but
- * all registers are 8-bit.
- *
- * The boardinfo 'io_range' is used to allow comedi to request the
- * proper range required by the board.
- *
- * The comedi_subdevice 'private' data is used to pass the register
- * offset to the (*insn_bits) functions to read/write the correct
- * registers.
- *
- * The basic register mapping looks like this:
- *
- * BASE+0 Isolated outputs 0-7 (write) / inputs 0-7 (read)
- * BASE+1 Isolated outputs 8-15 (write) / inputs 8-15 (read)
- * BASE+2 TTL outputs 0-7 (write) / inputs 0-7 (read)
- * BASE+3 TTL outputs 8-15 (write) / inputs 8-15 (read)
- *
- * The pcm3730 board does not have register BASE+1.
- *
- * The pcl725 and p8r8dio only have registers BASE+0 and BASE+1:
- *
- * BASE+0 Isolated outputs 0-7 (write) (read back on p8r8dio)
- * BASE+1 Isolated inputs 0-7 (read)
- *
- * The acl7225b and p16r16dio boards have this register mapping:
- *
- * BASE+0 Isolated outputs 0-7 (write) (read back)
- * BASE+1 Isolated outputs 8-15 (write) (read back)
- * BASE+2 Isolated inputs 0-7 (read)
- * BASE+3 Isolated inputs 8-15 (read)
- *
- * The pcl733 and pcl733 boards have this register mapping:
- *
- * BASE+0 Isolated outputs 0-7 (write) or inputs 0-7 (read)
- * BASE+1 Isolated outputs 8-15 (write) or inputs 8-15 (read)
- * BASE+2 Isolated outputs 16-23 (write) or inputs 16-23 (read)
- * BASE+3 Isolated outputs 24-31 (write) or inputs 24-31 (read)
- *
- * The opmm-1616-xt board has this register mapping:
- *
- * BASE+0 Isolated outputs 0-7 (write) (read back)
- * BASE+1 Isolated outputs 8-15 (write) (read back)
- * BASE+2 Isolated inputs 0-7 (read)
- * BASE+3 Isolated inputs 8-15 (read)
- *
- * These registers are not currently supported:
- *
- * BASE+2 Relay select register (write)
- * BASE+3 Board reset control register (write)
- * BASE+4 Interrupt control register (write)
- * BASE+4 Change detect 7-0 status register (read)
- * BASE+5 LED control register (write)
- * BASE+5 Change detect 15-8 status register (read)
- *
- * The pearl-mm-p board has this register mapping:
- *
- * BASE+0 Isolated outputs 0-7 (write)
- * BASE+1 Isolated outputs 8-15 (write)
- *
- * The ir104-pbf board has this register mapping:
- *
- * BASE+0 Isolated outputs 0-7 (write) (read back)
- * BASE+1 Isolated outputs 8-15 (write) (read back)
- * BASE+2 Isolated outputs 16-19 (write) (read back)
- * BASE+4 Isolated inputs 0-7 (read)
- * BASE+5 Isolated inputs 8-15 (read)
- * BASE+6 Isolated inputs 16-19 (read)
