* Blackfin: bf538: add missing SIC_RVECT defineMike Frysinger2010-10-221-0/+1
| | | | Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: punt short SPI MMR bit namesMike Frysinger2010-10-221-72/+0
| | | | | | | Now that the common header defines everything and the SPI drivers are using it, we can drop these duplicated global namespace polluters. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: Rename IRQ flags handling functionsDavid Howells2010-10-071-4/+4
| | | | | | | | | | | | | | | Rename h/w IRQ flags handling functions to be in line with what is expected for the irq renaming patch. This renames local_*_hw() to hard_local_*() using the following perl command: perl -pi -e 's/local_irq_(restore|enable|disable)_hw/hard_local_irq_\1/ or s/local_irq_save_hw([_a-z]*)[(]flags[)]/flags = hard_local_irq_save\1()/' `find arch/blackfin/ -name "*.[ch]"` and then fixing up asm/irqflags.h manually. Additionally, arch/hard_local_save_flags() and arch/hard_local_irq_save() both return the flags rather than passing it through the argument list. Signed-off-by: David Howells <dhowells@redhat.com>
* Blackfin: Split PLL code from mach-specific cdef headersDavid Howells2010-10-072-50/+63
| | | | | | | Split the PLL control code from the Blackfin machine-specific cdef headers so that the irqflags functions can be renamed without incurring a header loop. Signed-off-by: David Howells <dhowells@redhat.com>
* Blackfin: punt duplicate SPORT MMR definesMike Frysinger2010-08-271-107/+0
| | | | | | | The common bfin_sport.h header now has unified definitions of these, so stop polluting the global namespace. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: TWI: clean up the MMR namesMike Frysinger2010-08-062-71/+7
| | | | | | | | The standard short name for control is CTL and not CTRL. Use TWI0_xxx even on parts that only have one TWI bus to keep things simple. Drop all the cdef helpers since the bus driver takes care of everything. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: gpio/portmux: clean up whitespace corruptionMike Frysinger2010-08-061-54/+54
| | | | | | | Random tabs instead of spaces, mixes of the two, and unicode spaces instead of ascii spaces. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: add a GPIO_DEFAULT_BOOT_SPI_CSMike Frysinger2010-08-061-0/+1
| | | | | | | This is parallel to the existing P_DEFAULT_BOOT_SPI_CS, but in terms of the GPIO value so it can be used with the normal gpio API. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: punt duplicated CAN MMRsMike Frysinger2010-05-211-621/+0
| | | | | | | Now that there's a common header with everything unified, drop the defines from the global namespace. Pollution sucks. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: unify DMA masksMike Frysinger2009-12-151-46/+0
| | | | | | | Every Blackfin variant has the same DMA bit masks, so avoid duplicating them over and over in each mach header. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: unify duplicated power masksMike Frysinger2009-12-152-81/+0

* Blackfin: punt unused MXVR masksMike Frysinger2009-12-151-1013/+0
| | | | | | | There are no MXVR device drivers, and if someday there is, we can put these in a dedicated header rather than polluting the global namespace. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: scrub unused watchdog mmr masksMike Frysinger2009-12-151-35/+0
| | | | | | | The watchdog code doesn't need these, and the other parts had these punted, so keep the global namespace clean. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: scrub unused RTC masksMike Frysinger2009-12-151-50/+0
| | | | | | | The RTC driver code doesn't need these, and the other parts had these punted, so keep the global namespace clean. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bf538: add support for extended GPIO banksMichael Hennerich2009-12-153-27/+24
| | | | | | | | | | | The GPIOs on ports C/D/E on the BF538/BF539 do not behave the same way as the other ports on the part and the same way as all other Blackfin parts. The MMRs are programmed slightly different and they cannot be used to generate interrupts or wakeup a sleeping system. Since these guys don't fit into the existing code, create a simple gpiolib driver for them.

* Blackfin: update anomaly listsMike Frysinger2009-11-251-4/+14
| | | | | | | | Add some recently documented anomalies (473, 474, 475, 477). Also stick a "do not edit" notice in here so people know these are copies of some master version. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: mass clean up of copyright/licensing infoRobin Getz2009-10-078-175/+20
| | | | | | | | | | | | | | | | | | Bill Gatliff & David Brownell pointed out we were missing some copyrights, and licensing terms in some of the files in ./arch/blackfin, so this fixes things, and cleans them up. It also removes: - verbose GPL text(refer to the top level ./COPYING file) - file names (you are looking at the file) - bug url (it's in the ./MAINTAINERS file) - "or later" on GPL-2, when we did not have that right It also allows some Blackfin-specific assembly files to be under a BSD like license (for people to use them outside of Linux).

* Blackfin: unify memory map headersMike Frysinger2009-06-222-49/+9
| | | | | | | | | | Many aspects of the Blackfin memory map is exactly the same across all variants. Rather than copy and paste all of these duplicated values in each header, unify all of these into the common Blackfin memory map header file. In the process, push down BF561 SMP specific stuff to the BF561 specific header to keep the noise down. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
