* pasemi: DMA engine management libraryOlof Johansson2008-01-28
| | | | | | | | | | | | pasemi: DMA engine management library Introduce a DMA management library to manage the various DMA resources on the PA Semi SoCs. Since several drivers need to allocate these shared resources, provide some abstractions as well as allocation/free functions for channels, etc. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [netdrvr] irq handler minor cleanups in several driversJeff Garzik2008-01-28
| | | | | | | | | | | | | | | | | | | | | * use irq_handler_t where appropriate * no need to use 'irq' function arg, its already stored in a data struct * rename irq handler 'irq' argument to 'dummy', where the function has been analyzed and proven not to use its first argument. * remove always-false "dev_id == NULL" test from irq handlers * remove pointless casts from void* * declance: irq argument is not const * add KERN_xxx printk prefix * fix minor whitespace weirdness Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| * sh: add spi header and r2d platform data V3Magnus Damm2008-01-28
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds the header file asm/spi.h and board specific code for the r2d board. The header file contains a structure that should be used to point out a single spi bus. The board specific code for r2d is updated with such a structure for the new spi_sh_sci driver. The structure contains a chip select callback plus information about the R9701 rtc chip which is attached to the spi bus.

| * sh: update r7780rp interrupt codeMagnus Damm2008-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch updates the board specific irq code for r7780rp. The new code is very similar to the other highlander implementations, with the exception that the r7780rp handles pci interrupts using IRL. To simplify the pci code and use the same interrupt numbers as r7780mp and r7785rp we hook in to the cpu specific pci vectors. The pci interrupts and the push switch all work well with and without this patch. CF and AX88796 are not ok though and the source of the problem is unknown at this point. The AX88796 does for not detect it's proper mac address (IPL gets it right) and the kernel hangs on CF access. As a workaround this patch removes the CF and the AX88796 from the platform datain case of r7780rp. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: use declared coherent memory for dreamcast pci ethernet adapterMagnus Damm2008-01-27
| | | | | | | | | | | | | | | | | | | | | | This patch makes the dreamcast use the recently added declared coherent memory functions to point out the memory window suitable for dma. Apart from cleaning up, this gives the dreamcast a proper memory allocator for pci dma memory. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: declared coherent memory support V2Magnus Damm2008-01-27
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds declared coherent memory support to the sh architecture. All functions are based on the x86 implementation. Header files are adjusted to use the new functions instead of the former consistent_alloc() code. This version includes the few changes what were included in the fix patch together with modifications based on feedback from Paul.

| | | | | | | | | | | | | | | | | | | | Some of Sam's new work in the kbuild queue depend on ## concatenation within the linker script, which doesn't work when -traditional is enabled. -traditional is a legacy remnant anyways, and we no longer require it for anything, so kill it off completely.

| * sh: r2d - add lcd planel timings to sm501 platform dataMagnus Damm2008-01-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds timings to drive a Sharp LQ104V1DG21 lcd panel that can be hooked up to R2D-1 or R2D-PLUS. The sm501fb driver should leave the pins FPEN and VBIASEN alone, and this patch instructs the driver to do so by not setting flags flags for these pins. This patch works best together with the patch posted to the linux-fbdev-devel list "sm501fb: control panel pin usage with platform data flags", but this patch can be merged independently.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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: Fix up uImage target entry point.Thomas Betker2008-01-27
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the uImage target so that it generates a wrapped compressed vmlinux, rather than a wrapped zImage. The previous version matched the ARM, this version matches the PPC. However I would question how useful a self decompressing image is with a boot loader which does decompression, so I think this is more useful. I also feel it matches the descrition in the help text ("Compressed kernel image") better.

| * sh: Preparation for uncached jumps through PMB.Stuart Menefy2008-01-27
| | | | | | | | | | | | | | | | | | | | | | | | Presently most of the 29-bit physical parts do P1/P2 segmentation with a 1:1 cached/uncached mapping, jumping between the two to control the caching behaviour. This provides the basic infrastructure to maintain this behaviour on 32-bit physical parts that don't map P1/P2 at all, using a shiny new linker section and corresponding fixmap entry.
