9 	  DMA driver for MCUX LPC MCUs.
14 	int "Number of DMA descriptors to use"
17 	  Each DMA descriptor can be used to transfer (1024*width) bytes of data.
22 	int "Number of DMA channels to allocate memory for in driver"
25 	  The MCUX LPC DMA driver can save memory by not allocating static data
28 	  is "total number of unique DMA channels ever expected to be used, maximum
29 	  out of all DMA controllers". A value of 0 (default) means to allocate
30 	  as many channel data structures as the maximum number of DMA channels
31 	  in any DMA controller hardware. About 1 KB per 3-4 channels unused can
