spi: expose master transfer size limitation. On some SPI controllers it is not feasible to transfer arbitrary amount of data at once. When the limit on transfer size is a few kilobytes at least it makes sense to use the SPI hardware rather than reverting to gpio driver. The protocol drivers need a way to check that they do not sent overly long messages, though. Signed-off-by: Michal Suchanek <hramrach@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
