  "message": "spi: SuperH MSIOF SPI Master driver V2\n\nThis patch is V2 of SPI Master support for the SuperH MSIOF.\nFull duplex, spi mode 0-3, active high cs, 3-wire and lsb\nfirst should all be supported, but the driver has so far\nonly been tested with \"mmc_spi\".\n\nThe MSIOF hardware comes with 32-bit FIFOs for receive and\ntransmit, and this driver simply breaks the SPI messages\ninto FIFO-sized chunks. The MSIOF hardware manages the pins\nfor clock, receive and transmit (sck/miso/mosi), but the chip\nselect pin is managed by software and must be configured as\na regular GPIO pin by the board code.\n\nPerformance wise there is still room for improvement, but\non a Ecovec board with the built-in sh7724 MSIOF0 this driver\ngets Mini-sd read speeds of about half a megabyte per second.\n\nFuture work include better clock setup and merging of 8-bit\ntransfers into 32-bit words to reduce interrupt load and\nimprove throughput.\n\nSigned-off-by: Magnus Damm \u003cdamm@opensource.se\u003e\nSigned-off-by: Grant Likely \u003cgrant.likely@secretlab.ca\u003e\n",
