	  Each DMA descriptor can be used to transfer (1024*width) bytes of data.
	  Increase or decrease this value depending on the max number of data
	  transferred by the application.

config DMA_MCUX_LPC_NUMBER_OF_CHANNELS_ALLOCATED
	int "Number of DMA channels to allocate memory for in driver"
	default 0
	help
	  The MCUX LPC DMA driver can save memory by not allocating static data
	  depending on this value. So, the application can save some data memory
	  space by setting this value to suit its needs. The meaning of the value
	  is "total number of unique DMA channels ever expected to be used, maximum
	  out of all DMA controllers". A value of 0 (default) means to allocate
	  as many channel data structures as the maximum number of DMA channels
	  in any DMA controller hardware. About 1 KB per 3-4 channels unused can
	  be saved by fine tuning this Kconfig.
