* [MIPS] Add generic GPIO to Au1x00Florian Fainelli2007-07-10
| | | | | | | | | | This patch adds support for the generic GPIO API to Au1x00 boards. It requires the generic GPIO patch for MIPS boards by Yoichi Yuasa. Now there is a MIPS target using it, can you queue these patchset for 2.6.22 ? Thank you very much in advance.

* [PATCH] sysctl: remove insert_at_head from register_sysctlEric W. Biederman2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by: Eric W.

* [MIPS] Alchemy: Fix PCI-memory accessAlexander Bigga2007-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem was introduced in 2.6.18.3 with the casting of some 36bit-defines (PCI memory) in au1000.h to resource_size_t which may be u32 or u64 depending on the experimental CONFIG_RESOURCES_64BIT. With unset CONFIG_RESOURCES_64BIT, the pci-memory cannot be accessed because the ioremap in arch/mips/au1000/common/pci.c already used the truncated addresses. With set CONFIG_RESOURCES_64BIT, things get even worse, because PCI-scan aborts, due to resource conflict: request_resource() in arch/mips/pci/pci.c fails because the maximum iomem-address is 0xffffffff (32bit) but the pci-memory-start-address is 0x440000000 (36bit). To get pci working again, I propose the following patch: 1. remove the resource_size_t-casting from au1000.h again 2. make the casting in arch/mips/au1000/common/pci.c (it's allowed and necessary here. The 36bit-handling will be done in __fixup_bigphys_addr). With this patch pci works again like in 2.6.18.2, the gcc-compile warnings in pci.c are gone and it doesn't depend on CONFIG_EXPERIMENTAL.

* [MIPS] IRQ cleanupsAtsushi Nemoto2006-11-29
| | | | | | | | | | | | | | | | | | | | | This is a big irq cleanup patch. * Use set_irq_chip() to register irq_chip. * Initialize .mask, .unmask, .mask_ack field. Functions for these method are already exist in most case. * Do not initialize .startup, .shutdown, .enable, .disable fields if default routines provided by irq_chip_set_defaults() were suitable. * Remove redundant irq_desc initializations. * Remove unnecessary local_irq_save/local_irq_restore, spin_lock. With this cleanup, it would be easy to switch to slightly lightwait irq flow handlers (handle_level_irq(), etc.) instead of __do_IRQ(). Though whole this patch is quite large, changes in each irq_chip are not quite simple. Please review and test on your platform. Thanks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pass ticks to do_timer() and update_times(), and adjust x86_64 and s390 timer interrupt handler with this change. Currently update_times() calculates ticks by "jiffies - wall_jiffies", but callers of do_timer() should know how many ticks to update. Passing ticks get rid of this redundant calculation. Also there are another redundancy pointed out by Martin Schwidefsky. This cleanup make a barrier added by 5aee405c662ca644980c184774277fc6d0769a84 needless. So this patch removes it. As a bonus, this cleanup make wall_jiffies can be removed easily, since now wall_jiffies is always synced with jiffies. (This patch does not really remove wall_jiffies. It would be another cleanup patch) Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: "Eric W.

* | [PATCH] genirq: rename desc->handler to desc->chipIngo Molnar2006-06-29
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch-queue improves the generic IRQ layer to be truly generic, by adding various abstractions and features to it, without impacting existing functionality. While the queue can be best described as "fix and improve everything in the generic IRQ layer that we could think of", and thus it consists of many smaller features and lots of cleanups, the one feature that stands out most is the new 'irq chip' abstraction. The irq-chip abstraction is about describing and coding and IRQ controller driver by mapping its raw hardware capabilities [and quirks, if needed] in a straightforward way, without having to think about "IRQ flow" (level/edge/etc.) type of details. This stands in contrast with the current 'irq-type' model of genirq architectures, which 'mixes' raw hardware capabilities with 'flow' details. The patchset supports both types of irq controller designs at once, and converts i386 and x86_64 to the new irq-chip design. As a bonus side-effect of the irq-chip approach, chained interrupt controllers (master/slave PIC constructs, etc.) are now supported by design as well. The end result of this patchset intends to be simpler architecture-level code and more consolidation between architectures. We reused many bits of code and many concepts from Russell King's ARM IRQ layer, the merging of which was one of the motivations for this patchset. This patch: rename desc->handler to desc->chip. Originally i did not want to do this, because it's a big patch. But having both "desc->handler", "desc->handle_irq" and "action->handler" caused a large degree of confusion and made the code appear alot less clean than it truly is. I have also attempted a dual approach as well by introducing a desc->chip alias - but that just wasnt robust enough and broke frequently. So lets get over with this quickly. The conversion was done automatically via scripts and converts all the code in the kernel. This renaming patch is the first one amongst the patches, so that the remaining patches can stay flexible and can be merged and split up without having some big monolithic patch act as a merge barrier.

* [MIPS] arch/mips/au1000/time.c cleanupSergei Shtylyov2006-06-19
| | | | | | | | | Mark au1xxx_timer_setup() __init, just because it is. Get rid of unneeded extern's (note that (*do_gettimeoffset)() is already declared by <asm/time.c>) and an unused variable. Kill some whitespace... Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* [MIPS] Au1xxx: board specific irq code cleanupHerbert Valerio Riedel2006-06-19
| | | | | | | | Convert sizeof/sizeof use to use of ARRAY_SIZE macro, and annotate irqmap structures as __initdata. Signed-off-by: Herbert Valerio Riedel <hvr@gnu.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* [MIPS] Au1xx0: fix prom_getenv() to handle YAMON style environmentSergei Shtylyov2006-06-05
| | | | | | | | | Alchemy boards use YAMON which passes the environment variables as the tuples of strings (the name followed by the value) unlike PMON which passes "name=<val>" strings. Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* [MIPS] Save write-only Config.OD from being clobberedSergei Shtylyov2006-06-05
| | | | | | | | | | Save the Config.OD bit from being clobbered by coherency_setup(). This bit, when set, fixes various errata in the early steppings of Au1x00 SOCs. Unfortunately, the bit was write-only on the most early of them. In addition, also restore the bit after a wakeup from sleep.

* [MIPS] AU1xxx mips_timer_interrupt() fixesHerbert Valerio Riedel2006-05-31
| | | | | | | | | | common/au1000/irq.c was missing a mips_timer_interrupt() prototype, whereas in common/au1000/time.c the actual mips_timer_interrupt() implementation was missing an irq_exit() invocation, causing a preempt_count() leak.
