2016-03-28staging: comedi: ni_660x: refactor ni_gpct_to_660x_register()H Hartley Sweeten
Convert this big switch into an array and refactor ni_660x_gpct_{write,read}() functions to use the array to find the register offset. All the TIO (GPCT) registers are included in the array except for NITIO_G0_ABZ and NITIO_G1_ABZ. These registers only exist on the ni_pcimio m-series boards and this driver will never read/write them. Just in case someone adds a new entry to the enum ni_gpct_register in ni_tio.h, add a dev_warn() for any unhandled registers.

Use the comedi.h provided constants (enum ni_660x_pfi_routing) instead of defining new ones for the output sources. Use a switch to clarify the channel/source validation. For aesthetics, rename the private data members 'pfi_output_selects' and 'pfi_direction_bits'. Remove the 'min_counter_pfi_chan' and 'max_dio_pfi_chan' from enum ni_660x_constants.

Hard-coding the subdevice order is normally a bad idea. If a new subdevice is added, or removed, it could potentially break pretty badly. Remove the enum and associated NI_660X_GPCT_SUBDEV() helper that hard-code the subdevice order. Fix the (*auto_attach) so it initializes all the subdevices without depending on the hard-coded order.

This BUG_ON() happens if a mite DMA channel is already requested when an ansynchronous command is started for one of the counter subdevices.

2016-03-28staging: comedi: ni_660x: cleanup the NI660X_DMA_CFG register helpersH Hartley Sweeten
The BUG_ON() checks in the helper functions are not necessary. The mite driver quiries the PCI chip to determine the number of DMA channels. This is then used when a DMA channel is requested so the channel will always be in range. Convert the inline functions used to set the bits in the NI600X_DMA_CFG register into macros. Also convert the associated enum dma_selection. This clarifies the association with the register. Rename the associated 'dma_configuration_soft_copies' member of the private data to allow shorting some of the ugly long lines in the driver.
