This implementation will determine the fastest command by taking the supported commands from the flash and the controller, controller is always been a priority.

spi: omap3: add support for more word lengths 2013-11-12T09:02:44+00:00 Nikita Kiryanov nikita@compulab.co.il 2013-10-16T14:23:25+00:00 5753d09b1064a669e3be8f27e0f1fd008b96934a Current implementation only supports 8 bit word lengths, even though omap3 can handle anything between 4 and 32. Update the spi interface to support changing the SPI word length, and implement it in omap3_spi driver to support the full range of possible word lengths. This implementation is backwards compatible by defaulting to the old behavior of 8 bit word lengths. Also, it required a change to the omap3_spi non static I/O functions, but since they are not used anywhere else, no collateral changes are required.
