• 3322c7bbf   Blackfin: document SPI CS limitations with CPHA=0 ... Browse Code »

  With the Blackfin on-chip SPI peripheral, there is some logic tied to
  the CPHA bit whether the Slave Select Line is controlled by hardware
  (CPHA=0) or controlled by software (CPHA=1). However, the Linux SPI
  bus driver assumes that the Slave Select being asserted during the
  entire SPI transfer. So explain these small details for people who
  need certain SPI modes with standard CS behavior.
