2010-08-06Blackfin: TWI: clean up the MMR namesMike Frysinger2-71/+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>
2010-08-06Blackfin: gpio/portmux: clean up whitespace corruptionMike Frysinger1-54/+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>
2010-08-06Blackfin: add a GPIO_DEFAULT_BOOT_SPI_CSMike Frysinger1-0/+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>

2010-05-21Blackfin: punt duplicated CAN MMRsMike Frysinger1-621/+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>

2010-03-09Blackfin: add UART/SPORT early platform resourcesSonic Zhang1-0/+36

2010-03-09Blackfin: move SPORT UART resources to boards filesSonic Zhang1-0/+154
Rather than keeping the pins in the actual driver and worrying about a mess of Kconfig options, declare all the desired pin resources in the boards file. This lets people easily select the specific pins/ports for the normal emulated UART as well as GPIOs for CTS/RTS.

2009-12-15Blackfin: unify DMA masksMike Frysinger1-46/+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>

2009-12-15Blackfin: punt unused MXVR masksMike Frysinger1-1013/+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>
2009-12-15Blackfin: scrub unused watchdog mmr masksMike Frysinger1-35/+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>

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>
2009-12-15Blackfin: bf538: add support for extended GPIO banksMichael Hennerich5-27/+148
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.

2009-11-25Blackfin: update anomaly listsMike Frysinger1-4/+14

2009-10-08Blackfin: drop all simple-gpio board resourcesMike Frysinger1-15/+0
The simple-gpio has been replaced by the gpio sysfs interface, so drop the unused simple-gpio resources from all Blackfin boards. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-10-08Blackfin: drop cs_change_per_word settingMike Frysinger1-1/+0
Structs get initialized to 0 already, and we want to punt this field, so scrub it from all of our boards. Reported-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-10-07Blackfin: mass clean up of copyright/licensing infoRobin Getz11-249/+31
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).

2009-06-23Blackfin: unify memory map headersMike Frysinger2-49/+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>
