2012-03-03ARM: S3C2410: move mach-s3c2410/* into mach-s3c24xx/Kukjin Kim1-185/+0
This patch moves S3C2410 stuff into mach-s3c24xx/ directory so that we can merge the s3c24 series' directories to the just one mach-s3c24xx/ directory. And this patch is including following. - re-ordered alphabetically by option text at Kconfig and Makefile - removed unused option, MACH_N35 - fixed duplcated option name, S3C2410_DMA to S3C24XX_DMA which is in plat-s3c24xx/ Cc: Ben Dooks <ben-linux@fluff.org> Cc: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

2011-09-16ARM: S3C24XX: Remove hw_addr from s3c24xx dma channel declarationsHeiko Stuebner1-14/+0
According to commit c4806174c516d26bf4a72db1789cfc96e4950d07 (ARM: S3C2412: DMA: Remove I2S FIFO address) the S3C DMA API does not make use of hw_addr.to/from declared for some of the channels in mach-s3c24XX/dma.c Grepping through the kernel also did non reveal any new users of these properties since the mentioned commit.

2010-02-22ARM: SAMSUNG: Remove dma-plat.h to allow plat-s3c64xx to be removedBen Dooks1-1/+1
dma-plat.h is the last file left in plat-s3c64xx, but to remove it we must also change the use of dma-plat.h by the core code and the s3c24xx implementation. Rename the s3c24xx dma-plat.h in the common plat-samsung directory as it may be used for other ports. Move the specific dma bits into the mach-s3c64xx directory and update the build as needed.

2009-07-31ARM: S3C2410: Add S3C2410A sysdev.Ben Dooks1-0/+11
Add a sysdev S3C2410A sysdev to allow the differentiation of the S3C2410A from the S3C2410. This is needed for the CPUFREQ code to enable the extra features and update cpu specific information. Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-01[ARM] S3C24XX: dma.h should not include <mach/hardware.h>Ben Dooks1-0/+1
The dma.h header does not need to include <mach/hardware.h> as there is nothing it depends on. Remove the include and fixup the couple of places where <mach/map.h> was not explicitly included (dragged in via <mach/hardware.h>) Note, we have to fix arch/arm/plat-s3c24xx/pm.c which seems to rely on having <mach/hardware.h> included by this method.

2009-05-01[ARM] S3C24XX: DMA: Split hardware regs out of <mach/dma.h>Ben Dooks1-0/+1
The <mach/dma.h> is for the driver API for the DMA system and should not have anything relying on the CPU specific registers.

2008-11-29[ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King1-1/+0
When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.

This patch gets the DMA system for the S3C24XX ready for the S3C2443, which requires 6 dma channels at a different stride, and different base IRQ.

Patch from Ben Dooks The type naming in the s3c24xx dma code is riddled with typedefs creating _t types, from the code import from 2.4 which is contrary to the current Kernel coding style.

2006-08-18[ARM] 3753/1: S3C24XX: DMA fixesBen Dooks1-19/+144
Patch from Ben Dooks A number of small issues with the S3C24XX DMA have cropped up, which this patch fixes. These are: - check wether we can load another buff in start - update state handling in s3c2410_dma_lastxfer - only reload in irq if channel is not idle - more informative timeout errors (add source) - do not call request_irq() with irqs locked - added waitforstop function The patch also adds a S3C2410_DMAOP_STARTED for the occasions when the driver wants to ensure that the DMA system load state is resynced after loading.

2005-06-03[PATCH] ARM: 2694/1: [s3c2410/dma] release irq properly to fix kernel oopsAlbrecht Dreß1-0/+4
Patch from Albrecht Dreß Problem: When a module requests a DMA channel via the function s3c2410_dma_request(), this function requests the appropriate irq under the name of the client module. When the client module is unloaded, it calls s3c2410_dma_free() which does not free the irq. Consequently, when e.g. running "cat /proc/interrupts", the irq owner points to freed memory, leading to a kernel oops.

2005-04-17Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+1210
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!
