From 3322c7bbf60801da2a22d7bd88865d2dc3bd73ac Mon Sep 17 00:00:00 2001 From: Michael Hennerich Date: Tue, 6 Jul 2010 13:57:12 +0000 Subject: Blackfin: document SPI CS limitations with CPHA=0 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.
