linux-toradex.git/include/linux/spi/dw_spi.h, branch v2.6.34.4 Linux kernel for Apalis and Colibri modules spi/dw_spi: enable platform specific chipselect. 2010-01-21T14:24:29+00:00 George Shore george@georgeshore.com 2010-01-21T11:40:48+00:00 83fe518a839e317480e50a138ef4acd73510d7ce The driver core allows for a platform-specific chipselect assert/deassert function, however the chipselect function in the core doesn't take advantage of this fact. This enables the use of a custom function, should it be defined. Signed-off-by: George Shore <george@georgeshore.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

spi/dw_spi: refine the IRQ mode working flow 2010-01-20T20:49:45+00:00 Feng Tang feng.tang@intel.com 2010-01-20T20:49:45+00:00 552e450929a7298cc8834fd2824a60b2e914f70e Now dw_spi core fully supports 3 transfer modes: pure polling, DMA and IRQ mode. IRQ mode will use the FIFO half empty as the IRQ trigger, so each interface driver need set the fifo_len, so that core driver can handle it properly Signed-off-by: Feng Tang <feng.tang@intel.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
