* sh: fixup fpu.o compile orderKuninori Morimoto2011-04-181-3/+1Star
| | | | | | | | | | | | | | | | arch_ptrace() was modified to reference init_fpu() to fix up xstate initialization, which overlooked the fact that there are configurations that don't enable any of hard FPU support or emulation, resulting in build errors on DSP parts. Given that init_fpu() simply sets up the xstate slab cache and is side-stepped entirely for the DSP case, we can simply always build in the helper and fix up the references.

* sh: Break out cpuinfo_op procfs bits.Paul Mundt2010-11-091-1/+1
| | | | | | | Presently this is all inlined in setup.c, which is not really the place for it. Follow the x86 example and split it out into its own file. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: move sh clock-cpg.c contents to drivers/sh/clk-cpg.cMagnus Damm2010-05-131-1/+1
| | | | | | | | | | Move the CPG helpers to drivers/sh/clk-cpg.c V2. This to allow SH-Mobile ARM to share the code with SH. All functions except the legacy CPG stuff is moved. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Move over to dynamically allocated FPU context.Paul Mundt2010-01-131-0/+2
| | | | | | | | | | | | | | | | | | | | | This follows the x86 xstate changes and implements a task_xstate slab cache that is dynamically sized to match one of hard FP/soft FP/FPU-less. This also tidies up and consolidates some of the SH-2A/SH-4 FPU fragmentation. Now fpu state restorers are commonly defined, with the init_fpu()/fpu_init() mess reworked to follow the x86 convention. The fpu_init() register initialization has been replaced by xstate setup followed by writing out to hardware via the standard restore path. As init_fpu() now performs a slab allocation a secondary lighterweight restorer is also introduced for the context switch. In the future the DSP state will be rolled in here, too. More work remains for math emulation and the SH-5 FPU, which presently uses its own special (UP-only) interfaces. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Kill off legacy UBC wakeup cruft.Paul Mundt2009-10-161-1/+0Star
| | | | | | | | | | | | This code was added for some ancient SH-4 solution engines with peculiar boot ROMs that did silly things to the UBC MSTP bits. None of these have been in the wild for years, and these days the clock framework wraps up the MSTP bits, meaning that the UBC code is one of the few interfaces that is stomping MSTP bits underneath the clock framework. At this point the risks far outweigh any benefit this code provided, so just kill it off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: hwblk base implementationMagnus Damm2009-07-041-1/+1
| | | | | | | | | | | | | | | | | | | This patch is the hwblk base implementation, containing structures and shared functions dealing with hardware blocks. A each processor model should provide a list of hwblks and describe which module stop bit that is associated with each hwblck and how the hwblks are grouped together into areas. The shared code keeps track of the usage count for each hwblk and the areas. Fallback implementations for processor specific code are also kept as weak symbols. The clock framework, the runtime pm code and cpuidle will all tie into this hwblk implementation. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: clkfwk: Make clock-cpg usable for non-legacy platforms.Paul Mundt2009-05-221-1/+1
| | | | | | | | | | | This adds a new SH_CLK_CPG for parts that have CPG support. SH_CLK_CPG_LEGACY is made to depend on this, and still needs to be set for platforms that want clock-cpg to register the legacy clocks. With this new config item in place, it is now possible to start layering more generic CPG code in place while other platforms transition off of the legacy clocks.

* sh: clkfwk: Rework legacy CPG clock handling.Paul Mundt2009-05-131-0/+1
| | | | | | | | | This moves out the old legacy CPG clocks to their own file, and converts over the existing users. With these clocks going away and each CPU dealing with them on their own, CPUs can gradually move over to the new interface. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* [PATCH] sh: convert voyagergx to platform device, drop sh-busPaul Mundt2006-02-011-1/+1
| | | | | | | | | | | | 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.

* [PATCH] sh: IRQ handler updatesPaul Mundt2006-01-171-6/+3Star
| | | | | | | | | | | | | | This moves the various IRQ controller drivers into a new subdirectory, and also extends the INTC2 IRQ handler to also deal with SH7760 and SH7780 interrupts, rather than just ST-40. The old CONFIG_SH_GENERIC has also been removed from the IRQ definitions, as new ports are expected to be based off of CONFIG_SH_UNKNOWN. Since there are plenty of incompatible machvecs, CONFIG_SH_GENERIC doesn't make sense anymore.

* Linux-2.6.12-rc2Linus Torvalds2005-04-171-0/+16
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!
