- * Driver: ni_65xx
- * Description: National Instruments 65xx static dio boards
- * Author: Jon Grierson <jd@renko.co.uk>,
- * Frank Mori Hess <fmhess@users.sourceforge.net>
- * Status: testing
- * Devices: [National Instruments] PCI-6509 (pci-6509), PXI-6509 (pxi-6509),
- * PCI-6510 (pci-6510), PCI-6511 (pci-6511), PXI-6511 (pxi-6511),
- * PCI-6512 (pci-6512), PXI-6512 (pxi-6512), PCI-6513 (pci-6513),
- * PXI-6513 (pxi-6513), PCI-6514 (pci-6514), PXI-6514 (pxi-6514),
- * PCI-6515 (pxi-6515), PXI-6515 (pxi-6515), PCI-6516 (pci-6516),
- * PCI-6517 (pci-6517), PCI-6518 (pci-6518), PCI-6519 (pci-6519),
- * PCI-6520 (pci-6520), PCI-6521 (pci-6521), PXI-6521 (pxi-6521),
- * PCI-6528 (pci-6528), PXI-6528 (pxi-6528)
- * Updated: Mon, 21 Jul 2014 12:49:58 +0000
- *
- * Configuration Options: not applicable, uses PCI auto config
- *
- * Based on the PCI-6527 driver by ds.
- * The interrupt subdevice (subdevice 3) is probably broken for all
- * boards except maybe the 6514.
- *
- * This driver previously inverted the outputs on PCI-6513 through to
- * PCI-6519 and on PXI-6513 through to PXI-6515. It no longer inverts
- * outputs on those cards by default as it didn't make much sense. If
- * you require the outputs to be inverted on those cards for legacy
- * reasons, set the module parameter "legacy_invert_outputs=true" when
- * loading the module, or set "ni_65xx.legacy_invert_outputs=true" on
- * the kernel command line if the driver is built in to the kernel.
