This function takes an irq_handler_t function, but the prototype in the header doesn't match the function definition. This is due to the smp headers needing to avoid circular dependencies. So change the function to take a simple pointer. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

The common asm-generic non-atomic bitops.h defines test_bit() for us, but we need to use our own version. So redirect the definition of this func to avoid having to inline the rest of the asm-generic file. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

The cpu maps are defines provided by common linux/cpumask.h, not local variables. So stop exporting them locally and include the right header for their definition. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

The external functions are named __raw_xxx, not arch_xxx, so rename the prototypes to match reality. This fixes some simple build errors in the bfin_ksyms.c code which exports these helpers to modules. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Rather than maintain Kconfig entries where people have to enter raw numbers and hardcode lists of addresses/pins in the driver itself, push it all to platform resources. This lets us simplify the driver, the Kconfig, and gives board porters greater flexibility. In the process, we need to also start supporting the early platform interface. Not a big deal, but it causes the patch to be bigger than a simple resource relocation. All the Blackfin boards already have their resources updated and in place for this change.

These were only included because of the irq handling of the PLL funcs, and those PLL funcs have been moved out into their own header now. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

The defBF512.h header exists only to include defBF51x_base.h, and it is the only place where defBF51x_base.h is included. So move the contents of the defBF51x_base.h header into the defBF512.h header. Same situation for the other def/cdef pairs. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Mike Frysinger authored
The main asm/blackfin.h header will pull in mach/blackfin.h to get all the fun Blackfin defines. So having any of the sub-mach headers trying to include asm/blackfin.h makes no sense -- punt it. The mach/blackfin.h header takes care of including the part-specific def headers which in turn will include any other needed def file. Similarly, it takes care of pulling in the part-specific cdef header. So move this logic out of the blackfin.h when necessary. Further, make sure the cdef headers do not waste time including the def headers again. Since all parts need the common def/cdef headers, move this logic out of the part-specific headers and into the mach/blackfin.h file. Finally, we need to split the BF539 def header since the BF538 does not have MXVR and we don't want to expose those MMRs. So now all parts should have the same behavior: mach/blackfin.h asm/def_LPBlackfin.h part-specific def.h if ! asm asm/cdef_LPBlackfin.h part-specific cdef.h And the sub def/cdef headers only tail into what they need.

We don't want the BF533 to be different in terms of its MMR headers, so merge the FIO_FLAG helpers back into the normal place. To avoid circular dependencies with headers, turn the inline C funcs into CPP defines. Not like there will be any code size differences. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Since the SMP code paths tend to compile fail a lot, start a SMP defconfig so our nightly build tools will automatically test it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

We don't want people banging on MMRs directly. As for the ip0x board, it shouldn't need to muck with the CS pin directly as the Blackfin SPI bus master driver takes care of driving this. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Use the same naming convention for DMA traffic MMRs (most were legacy anyways) so we can avoid useless ifdef trees. Same goes for MDMA names -- this actually allows us to undo a bunch of ifdef redirects that existed for this purpose alone. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Each Blackfin port has been duplicating UART structures and defines when there really is no need for it. So start a new bfin_serial.h header to unify all these pieces and give ourselves a fresh start. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Mike Frysinger authored
We're in the process of cleaning up the global Blackfin namespace, so the bfin_sir driver needs to pull in the serial header explicitly now. This does add a little transitional cruft to keep things compiling, but a follow up patch in this series will cull that. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Note that if dma_unmap_single() ever starts * to do real work on ARM, we'd need to clean up mappings * for previous transfers on *ALL* exits of this loop... */ as the comment is not true - we do work in dma_unmap() functions, particularly on ARMv6 and above. I've corrected the existing unmap functions but if any others are required they must be added ASAP.
