2008-04-24[Blackfin] arch: Prevent potential Core Hang situationMichael Hennerich1-4/+33
If the new value written to the PLL_CTL or VR_CTL register is the same as the previous value, the PLL wake-up will occur immediately (PLL is already locked), but the core and system clock will be bypassed for the PLL_LOCKCNT duration. For this interval, code will execute at the CLKIN rate instead of at the expected CCLK rate. Software should guard against this condition by comparing the current value to the new value before writing the new value.

2007-07-12Blackfin arch: initial supporting for BF548-EZKITRoy Huang1-20/+26
The ADSP-BF54x was specifically designed to meet the needs of convergent multimedia applications where system performance and cost are essential ingredients. The integration of multimedia, human interface, and connectivity peripherals combined with increased system bandwidth and on-chip memory provides customers a platform to design the most demanding applications. Since now, ADSP-BF54x will be supported in the Linux kernel and bunch of related drivers such as USB OTG, ATAPI, NAND flash controller, LCD framebuffer, sound, touch screen will be submitted later. Please enjoy the show. Signed-off-by: Roy Huang <roy.huang@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>
2007-05-21Blackfin arch: update blackfin header files to latest one in VDSP.Bryan Wu1-0/+2722
a) add new processor BF52x/BF54x header files b) update blackfin BF533/BF537/BF561 header files to latest one in VDSP. c) scrub watchdog/rtc masks from headers as we dont need/want them (too generic and the drivers dont use them) Signed-off-by: Mike Frysinger <michael.frysinger@analog.com> Signed-off-by: Roy Huang <roy.huang@analog.com> Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
