 * Driver: adl_pci6208
 * Description: ADLink PCI-6208/6216 Series Multi-channel Analog Output Cards
 * Devices: [ADLink] PCI-6208 (adl_pci6208), PCI-6216
 * Author: nsyeow <[email protected]>
 * Updated: Wed, 11 Feb 2015 11:37:18 +0000
 * Status: untested
 *
 * Configuration Options: not applicable, uses PCI auto config
 *
 * All supported devices share the same PCI device ID and are treated as a
 * PCI-6216 with 16 analog output channels.  On a PCI-6208, the upper 8
 * channels exist in registers, but don't go to DAC chips.
