[PATCH 5/5] spi: sh-msiof: Add DMA support

2014-06-20 Thread Geert Uytterhoeven
Add DMA support to the MSIOF driver using platform data. As MSIOF DMA is limited to 32-bit words (requiring byte/wordswapping for smaller wordsizes), and the group length is limited to 256 words, DMA is performed on two fixed pages, allocated and mapped at driver initialization time. Performance
