Rasmus Villemoes af0e624290 spi: spi-fsl-spi: automatically adapt bits-per-word in cpu mode ... Taking one interrupt for every byte is rather slow. Since the controller is perfectly capable of transmitting 32 bits at a time, change t->bits_per-word to 32 when the length is divisible by 4 and large enough that the reduced number of interrupts easily compensates for the one or two extra fsl_spi_setup_transfer() calls this causes.
