Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/lliubbo/blackfin
Pull blackfin changes from Bob Liu: "The biggest change was added an new processor(bf60x series). Bf60x series processor of blackfin can up to 1GHz with Hardware Support for HD Video Analytics, it use the same blackfin ISA but with some changes on system buses, interrupt controller and peripheral devices. Added dir arch/blackfin/mach-bf609/ and did some changes to the framework made linux working fine on the reference board bf609-ezkit now." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/lliubbo/blackfin: (41 commits) blackfin: fix build after add bf60x mach/pm.h blackfin: twi: include linux/i2c.h blackfin: bf60x: add head file for crc controller blackfin: bf60x: twi: work around temporary anomaly 0501001 blackfin: twi: Move TWI MMR access macro to twi head file blackfin: twi: Move TWI peripheral pin request array to platform data blackfin: bf60x: anomaly: Add a temporary anomaly 0501001 blackfin: bf60x: Rename the DDR controller macro blackfin: mach-bf609: pm: cleanup bfin_deepsleep blackfin: bf60x: cleanup get clock code blackfin: bf60x: pm: Add a debug option to calculate kernel wakeup time. blackfin: bf60x: add wakeup source select blackfin: bf60x: make clock changeable in kernel menuconfig blackfin:mach-bf609: fix norflash for bf609-ezkit blackfin: mach-bf609: add can_wakeup to ethernet device blackfin: remove redundant CONFIG_BF60x macro blackfin: rotary: Add pm_wakeup flag to platform data structure. bfin_gpio: fix bf548-ezkit kernel fail to boot bfin_dma: fix initcall return error in proc_dma_init() Blackfin: delete fork func ...
