* sh: remove voyagergxMagnus Damm2008-01-27
| | | | | | | | | This patch removes redundant irq handling code together with unused consistent alloc code. R2D uart setup code is changed to use sm501-regs.h and unused header files are removed. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: intc - remove default interrupt priority tablesMagnus Damm2008-01-27
| | | | | | | | | | | | | This patch removes interrupt priority tables from the intc code. Optimal priority assignment varies with embedded application anyway, so keeping the interrupt priority tables together with cpu-specific code doesn't make sense. The function intc_set_priority() should be used instead to set the desired interrupt priority level. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Add -Werror for clean directories.Paul Mundt2007-11-06
| | | | | | Follow the MIPS and sparc64 changes for -Werror instrumentation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: intc - mark data structures as __initdataMagnus Damm2007-09-20
| | | | | | | | | | | With the intc core improved it is now possible to put the intc data structures in the initdata section. Version two of this patch puts the __initdata inside DECLARE_INTC_DESC() and removes the __initdata included in the board specific r2d code.

* sh: intc - rework core codeMagnus Damm2007-09-20
| | | | | | | | | | | | | | | | | This patch reworks the intc core, implementing the following features: - Support dual priority registers - one set and one clear register - All 8/16/32 bit register combinations are now supported - Both single mask and single enable bitmap register are supported - Add code to set interrupt priority - Speedup sense and priority configuration code - Allocate data using bootmem, allows intc data structures to be __initdata - Save memory - allocated memory footprint is smaller than intc structures Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: intc - convert voyagergx codeMagnus Damm2007-09-20
| | | | | | | | | | | | | | | | | | | | This patch converts the sh-specific voyagergx interrupt code to make use of intc. A lot of "interesting" old cruft gets replaced with intc tables and some simple demux code. - All interrupt sources in the sm501 data sheet are now in the header. - The number and order of IRQ values are disconnected from register bits. - Interrupt sources now start from IRQ 200. - set_irq_chained_handler() is now used to hook up the demux function. In the future it would probably make sense to move the interrupt demuxer into into the mfd driver, but this is probably a nice step in the right direction until that happens. Tested on a R2D-1 board using the serial port hooked up to the sm501. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: voyagergx: Fix build warnings.Paul Mundt2007-06-03
| | | | | | | pr_debug() was using a %x on an unsigned long, which was making the build a bit noisy. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: rts7751r2d board updates.Paul Mundt2007-02-15
| | | | | | | | This tidies up some of the rts7751r2d mess and gets it booting again. Update the defconfig, too. Signed-off-by: Masayuki Hosokawa <hosokawa@ace-jp.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Cleanup board header directories.Paul Mundt2006-10-19
| | | | | | | | Now with the ide.h mess sorted out, most of these boards don't need their own directory. Move the headers out, and update the driver paths. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | Trivial fixes for build breakage introduced by IRQ handler changes. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Cleanup IRQ disabling for hardirq handlers.Paul Mundt2006-09-27
| | | | | | | | The generic hardirq layer already takes care of a lot of the appropriate locking and disabling for us, no need to duplicate it in the handlers.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Move voyagergx_reg.h to a more sensible place.Paul Mundt2006-09-27
| | | | | | | Other boards require this as well, so move it out of the rts7751r2d directory. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* [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.

* [PATCH] sh: convert voyagergx to platform device, drop sh-busPaul Mundt2006-02-01
| | | | | | | | | | | | Trivial patch updating the voyagergx cchip code to reference a platform device instead, now that the dma mask is taken care of. Given this, there's no longer any reason to drag around the SH-bus code, so kill that off entirely.

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!
