2009-02-27sh: multiple vectors per irq - baseMagnus Damm
Instead of keeping the single vector -> single linux irq mapping we extend the intc code to support merging of vectors to a single linux irq. This helps processors such as sh7750, sh7780 and sh7785 which have more vectors than masking ability. With this patch in place we can modify the intc tables to use one irq per maskable irq source. Please note the following: - If multiple vectors share the same enum then only the first vector will be available as a linux irq. - Drivers may need to be rewritten to get pending irq source from the hardware block instead of irq number. This patch together with the sh7785 specific intc tables solves DMA controller irq issues related to buggy interrupt masking.

2009-02-27sh: maple: Support block reads and writes.Adrian McMenamin
This patch updates the maple bus to support asynchronous block reads and writes as well as generally improving the quality of the code and supporting concurrency (all needed to support the Dreamcast visual memory unit - a driver will also be posted for that). Changes in the bus driver necessitate some changes in the two maple bus input drivers that are currently in mainline. As well as supporting block reads and writes this code clean up removes some poor handling of locks, uses an atomic status variable to serialise access to devices and more robusly handles the general performance problems of the bus.

2008-10-01sh: Move the shared INTC code out to drivers/sh/Paul Mundt
The INTC code will be re-used across different architectures, so move this out to drivers/sh/ and include/linux/sh_intc.h respectively. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-08-04maple: Kill useless private_data pointer.Paul Mundt
We can simply wrap in to the dev_set/get_drvdata(), there's no reason to track an extra level of private data on top of the struct device. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-08-04maple: Clean up maple_driver_register/unregister routines.Paul Mundt
These were completely inconsistent. Clean these up to take a maple_driver pointer directly for consistency. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-07-29sh/maple: clean maple bus codeAdrian McMenamin
This patch cleans up the handling of the maple bus queue to remove the risk of races when adding packets. It also removes references to the redundant connect and disconnect functions. Signed-off-by: Adrian McMenamin <adrian@mcmen.demon.co.uk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-02-26maple: fix device detectionAdrian McMenamin
The maple bus driver that went into the kernel mainline in September 2007 contained some bugs which were revealed by the update of the kobj code for the current release series. Unfortunately those bugs also helped ensure maple devices were properly detected. This patch (against the current git) now ensures that devices are properly detected again. (A previous attempt to fix this by delaying initialisation only partially fixed this - as became apparent when the bus was fully loaded) Signed-off-by: Adrian McMenamin <adrian@mcmen.demon.co.uk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-02-14maple: improve detection of attached peripheralsAdrian McMenamin
Improve device detection for maple through longer delay Experience suggests that a much longer delay in setting up the Maple bus on the Dreamcast leads to better hardware detection. Signed-off-by: Adrian McMenamin <adrian@mcmen.demon.co.uk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-02-14maple: more robust device detection.Adrian McMenamin
Replacement second-in-series patch: This patch fixes up memory leaks and, by delaying initialisation, makes device detection more robust. It also makes clearer the difference between struct maple_device and struct device, as well as cleaning up the interrupt request code (without changing its function in any way). Also now removes redundant registration checking. Signed-off-by: Adrian McMenamin <adrian@mcmen.demon.co.uk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-02-14maple: fix up whitespace damage.Adrian McMenamin
This patch is fundamentally about fixing up the whitespace problems introduced by my previous patch (that brought the code into mainline). A second patch will follow that will fix memory leaks. The two need to be applied sequentially. Signed-off-by: Adrian McMenamin <adrian@mcmen.demon.co.uk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-09-21sh: Add maple bus support for the SEGA Dreamcast.Adrian McMenamin
The Maple bus is SEGA's proprietary serial bus for peripherals (keyboard, mouse, controller etc). The bus is capable of some (limited) hotplugging and operates at up to 2 M/bits. Drivers of one sort or another existed/exist for 2.4 and a rudimentary port, which didn't support the 2.6 device driver model was also in existence. This driver - for the bus logic itself and for the keyboard (other drivers will follow) are based on the code and concepts of those old drivers but have lots of completely rewritten parts. I have the maple bus code as a built in now as that seems the sane and rational way to handle something like that - you either want the bus or you don't.

2005-11-07[PATCH] superhyway: multiple block support and VCR reworkPaul Mundt
This extends the API somewhat to allow for platform-specific VCR reading and writing. Some platforms (like SH4-202) implement the VCR in a split VCRL and VCRH, but end up being in reverse order or have other quirks that need to be dealt with, so we add a set of superhyway_ops per-bus to accomodate this. We also have to extend the per-device resources somewhat, as some devices now conveniently split control and data blocks. So we allow a platform to register its set of SuperHyway devices via superhyway_add_devices() with the control block always ordered as the first resource (as this is the one that userspace cares about).

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!
