2018-03-16 | arch: remove blackfin port | Arnd Bergmann | 1 | -16/+0 | |
The Analog Devices Blackfin port was added in 2007 and was rather active for a while, but all work on it has come to a standstill over time, as Analog have changed their product line-up. Aaron Wu confirmed that the architecture port is no longer relevant, and multiple people suggested removing blackfin independently because of some of its oddities like a non-working SMP port, and the amount of duplication between the chip variants, which cause extra work when doing cross-architecture changes.

2010-08-06 | Blackfin: document SPI CS limitations with CPHA=0 | Michael Hennerich | 1 | -0/+14 | |
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.
