2018-03-16arch: remove blackfin portArnd Bergmann1-214/+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.

2017-08-27blackfin: merge the two TWI header filesWolfram Sang1-1/+133
There seems to be no need for separate ones since all users include both files anyhow. Merge them because include/linux/i2c is to be deprecated. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2014-03-09i2c: bfin-twi: remove unnecessary Blackfin SSYNC from the driverSonic Zhang1-2/+21
Put necessary SSYNC code into blackfin twi arch header. The generic TWI driver should not contain any architecture specific code. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2014-03-09i2c: bfin-twi: move bits macros and structs in header from arch include to ↵Sonic Zhang1-125/+1
generic include The ADI TWI peripheral is not binding to the Blackfin processor only. The bits macros and structs should be put in the generic include header. And update head file path in drivers accordingly. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2012-12-13Blackfin: twi: Add missing __iomem annotationLars-Peter Clausen1-1/+1
Add a missing __iomem to the bfin_twi_iface struct's regs_base field.
