2007-03-12sh: Fix PCI BAR address-space wraparound.Hideo Saito
When a SH7751R system includes a card that has wide range space like a graphics card, the pci-pci bridge controller can't set the correct address range. For example, when *lower_limit is 0xfd000000 and bar_size is 0x4000000, in the following code at arch/sh/drivers/pci/pci-auto.c, 0x0 is set in bar_value. pciauto_setup_bars() { ... bar_value = ((*lower_limit - 1) & ~(bar_size - 1)) + bar_size; ... *lower_limit = bar_value + bar_size; } As a result, 0x4000000 is set in *lower_limit, but this value is wrong. The following patch avoids this problem by checking the range of the value and refusing to update the BAR if the calculated value ends up being bogus.

2007-02-14sh: Kill off dead bigsur and ec3104 boards.Paul Mundt
Neither of these have had any maintenance in years, and there's no interest in keeping them straggling along. These have already been slated for removal some time, so finally just get rid of them. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-02-13sh: heartbeat consolidation for banked LEDs.Paul Mundt
This consolidates the various board heartbeat LED implementations, used for strobing the load average across a LED bank. Those boards not implementing a full bank can hook in via the LED class. We leave the compat hook in the machvec for now until those non-banked boards are able to migrate to the drivers/leds. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-13sh: SH-DMAC compile fixesManuel Lauss
This patch does the following: - remove the make_ipr_irq stuff from dma-sh.c and replace it with a simple channel<->irq mapping table. - add DMTEx_IRQ constants for sh4 cpus - fix sh7751 DMAE irq number The SH7780 uses the same IRQs for DMA as other SH4 types, so I put the constants on top of the dma.h file. Other CPU types need to #define their own DMTEx_IRQ contants in their appropriate header. Signed-off-by: Manuel Lauss <mano@roarinelk.homelinux.net> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-12sh: push-switch fixups for work_struct API damage.Paul Mundt
INIT_WORK() dropped the data arg, so now we have to stash an extra pointer and backpedal instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-06sh: sh775x/titan fixes for irq header changes.Jamie Lenehan
The following moves the creation of IPR interupts into setup-7750.c and updates a few other things to make it all work after the "Drop CPU subtype IRQ headers" commit. It boots and runs fine on my titan board. - adds an ipr_idx to the ipr_data and uses a function in the subtype code to calculate the address of the IPR registers - adds a function to enable individual interrupt mode for externals in the subtype code and calls that from the titan board code instead of doing it directly. - I changed the shift in the ipr_data to be the actual # of bits to shift, instead of the numnber / 4 - made it easier to match with the manual.

2006-12-06sh: dma-api channel capability extensions.Mark Glaisher
This extends the SH DMA API for allowing handling of DMA channels based off of their respective capabilities. A couple of functions are added to the existing API, the core bits are register_chan_caps() for registering channel capabilities, and request_dma_bycap() for fetching a channel dynamically based off of a capability set.

2006-12-06sh: Drop name overload in dma-sh.Paul Mundt
Pass along the dev_id from request_dma() all the way down, rather than inserting an artificial name relating to the TEI line that we were doing before. This makes the line a bit less obvious, but dev_id is the proper behaviour for this regardless. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-06sh: Make dma-isa depend on ISA_DMA_API.Paul Mundt
Previously we linked in the ISA DMA wrapper unconditionally. As there are very few users of this, it's better to make it conditional. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-06sh: dma-sysfs fixes.Paul Mundt

2006-12-06sh: generic push-switch framework.Paul Mundt
This adds support for a generic push switch framework. Adaptable for various switches, including GPIO switches and the push switches commonly found on Renesas debug boards. This allows switch states to be trivially reported through sysfs. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-06sh: Drop CPU subtype IRQ headers.Paul Mundt
This drops the various IRQ headers that were floating around and primarily providing hardcoded IRQ definitions for the various CPU subtypes. This quickly got to be an unmaintainable mess, made even more evident by the subtle breakage introduced by the SH-2 and SH-2A changes. Now that subtypes are able to register IRQ maps directly, just rip all of the headers out. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-10-31sh: Fix IPR-IRQ's for IRQ-chip change breakage.Jamie Lenehan
The conversion from IPR-IRQ to IRQ-chip resulted in the ipr data being allocated in a local variable in make_ipr_irq - breaking anything using IPR interrupts. This changes all of the callers of make_ipr_irq to allocate a static structure containing the IPR data which is then passed to make_ipr_irq. This removes the need for make_ipr_irq to allocate any additional space for the IPR information. Signed-off-by: Jamie Lenehan <lenehan@twibble.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-10-19sh: Cleanup board header directories.Paul Mundt

2006-09-27sh: Inhibit mapping PCI apertures through page tables.Paul Mundt
Inhibit mapping through page tables in __ioremap() for PCI memory apertures on SH7751 and SH7780-style PCI controllers, translation is not possible for these areas. For other users that map a small window in P1/P2 space, ioremap() traps that already, and should never make it to __ioremap(). Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2006-01-16[PATCH] sh: DMA updatesPaul Mundt
This extends the current SH DMA API somewhat to support a proper virtual channel abstraction, and also works to represent this through the driver model by giving each DMAC its own platform device. There's also a few other minor changes to support a few new CPU subtypes, and make TEI generation for the SH DMAC configurable.

2005-10-30[PATCH] fix missing includesTim Schmielau
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
