| | | | | | | | | | This patch adds support for the generic GPIO API to Au1x00 boards. It requires the generic GPIO patch for MIPS boards by Yoichi Yuasa.

* [PATCH] sysctl: remove insert_at_head from register_sysctlEric W. Biederman2007-02-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Bigga2007-01-101-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Nemoto2006-11-301-41/+22
| | | | | | | | | | | | | | | | | | | | | 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.

* [MIPS] Fixup migration to GENERIC_TIMEAtsushi Nemoto2006-10-311-98/+0
| | | | | | | | | | | | | | | | | | | | | Since we already moved to GENERIC_TIME, we should implement alternatives of old do_gettimeoffset routines to get sub-jiffies resolution from gettimeofday(). This patch includes: * MIPS clocksource support (based on works by Manish Lachwani). * remove unused gettimeoffset routines and related codes. * remove unised 64bit do_div64_32(). * simplify mips_hpt_init. (no argument needed, __init tag) * simplify c0_hpt_timer_init. (no need to write to c0_count) * remove some hpt_init routines. * mips_hpt_mask variable to specify bitmask of hpt value. * convert jmr3927_do_gettimeoffset to jmr3927_hpt_read. * convert ip27_do_gettimeoffset to ip27_hpt_read. * convert bcm1480_do_gettimeoffset to bcm1480_hpt_read. * simplify sb1250 hpt functions.

* [PATCH] simplify update_times (avoid jiffies/jiffies_64 aliasing problem)Atsushi Nemoto2006-09-291-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
