Rajeshwari Shinde c4a796329d spi: exynos: Support word transfers ... Since SPI register access is so expensive, it is worth transferring data a word at a time if we can. This complicates the driver unfortunately. Use the byte-swapping feature to avoid having to convert to/from big endian in software. This change increases speed from about 2MB/s to about 4.5MB/s.
