* Blackfin: sport_uart resources: remove unused secondary RX/TX pinsSonic Zhang2011-01-1018-36/+36
| | | | | | | | The SPORT/UART driver doesn't use the secondary channel pins, so don't try and request them thus keeping other drivers from using them. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: tll6527m: fix spelling in unused code (struct name)Stefan Weil2011-01-101-1/+1
| | | | | | | | | | | | | platfrom -> platform This changes a struct name. The related code is conditionally compiled and won't work because the include file linux/gpio-decoder.h is missing, so removing this code would be an even better solution. If the missing include file is added, it must fix the spelling, too. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: no-mpu: fix masking of small uncached dma regionSonic Zhang2011-01-101-1/+1
| | | | | | | | | | | When using an uncached DMA region less than 1 MiB, we try to mask off the whole last 1 MiB for it. Unfortunately, this fails as we forgot to subtract one from the calculated mask, leading to the region still be marked as cacheable.

* Blackfin: pm: drop irq save/restore in standby and suspend to mem callbackSteven Miao2011-01-101-10/+0
| | | | | | | | | Since linux-2.6.31, the kernel suspend framework will do disable_irq/enable_irq, so save/restore irq in standby and suspend to mem callback should be dropped.

* Blackfin: SMP: rewrite IPI handling to avoid memory allocationYi Li2011-01-103-133/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, sending an interprocessor interrupt (IPI) requires building up a message dynamically which means memory allocation. But often times, we will want to send an IPI in low level contexts where allocation is not possible which may lead to a panic(). So create a per-cpu static array for the message queue and use that instead. Further, while we have two supplemental interrupts, we are currently only using one of them. So use the second one for the most common IPI message of all -- smp_send_reschedule(). This avoids ugly contention for locks which in turn would require an IPI message ... In general, this improves SMP performance, and in some cases allows the SMP port to work in places it wouldn't before. Such as the PREEMPT_RT state where the slab is protected by a per-cpu spin lock. If the slab kmalloc/kfree were to put the task to sleep, and that task was actually the IPI handler, then the system falls down yet again. After running some various stress tests on the system, the static limit of 5 messages seems to work. On the off chance even this overflows, we simply panic(), and we can review that scenario to see if the limit needs to be increased a bit more.

| | | | | | | | | The BF561 mem_map.h header has the __ASSEMBLY__/CONFIG_SMP checks out of order which leads to build errors for assembly code that happens to include this file. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: SMP: tweak platform_request_ipi() usageGraf Yang2011-01-103-3/+5
| | | | | | | | | | 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.

* serial: bfin_5xx: move resources into board filesSonic Zhang2011-01-101-0/+12
| | | | | | | | | | | | | | | | | | 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.

* Blackfin: drop asm/irq.h include from mach headersMike Frysinger2011-01-107-21/+0
| | | | | | | 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>
* Blackfin: bf51x/bf52x: drop redundant "base" def/cdef headerMike Frysinger2011-01-108-4953/+4893
| | | | | | | | | | 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>
* Blackfin: clean up mach header includesMike Frysinger2011-01-1045-2142/+1990
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Soon resource data will get automatically populated from a set of autogenerated data from TI's hardware database for the OMAP platform. Such database, might not have resources at the expected order by the current drivers. While we could hack in some exceptions to that tool to generate resources in a specific order, it seems less fragile to use the resource name instead. That way, no matter what order the resources are generated, the driver still work. Modified the OMAP, Blackfin and Davinci architecture files to add the name of the IRQs in the resource structures and musb driver to use the platform_get_irq_byname() api to get the device and dma irq numbers instead of using the index.
