ARM: S3C64XX: Move core support to mach-s3c64xx

2010-02-20T22:33:54+00:00

Move the core S3C64XX support to mach-s3c64xx as it is unlikely to be used outside of this directory. Also move the SoC header files in with it. This includes the clock, cpu, cpufreq, dma, gpiolib and pll support. Signed-off-by: Ben Dooks

ARM: S3C64XX: Move headers into machine include directory

2010-02-20T22:31:17+00:00

Move the register and GPIO definition files from plat-s3c64xx into the machine include direcotry as they are unlikely to be reused outside mach-s3c64xx. This move includes removing the empty and replacing it with the implementation. Signed-off-by: Ben Dooks

ARM: S3C64XX: DMA: Free node for non-circular queues

2009-11-09T23:51:19+00:00

We need to free the buff and lli nodes if the buffer queue is not CIRCULAR. Signed-off-by: Jassi Brar Signed-off-by: Ben Dooks

ARM: S3C64XX: DMA: Callback with correct buffer pointer

2009-11-09T23:51:03+00:00

buffdone callback should be called per buffer request with pointer to the latest serviced request. 'next' should point to the one next to currently active. Signed-off-by: Jassi Brar Signed-off-by: Ben Dooks

ARM: S3C64XX: DMA: Make src and dst transfer size same

2009-11-09T23:50:42+00:00

Some devices don't seem to work if the source and desitnation transfer widths are not same. For example, SPI dma xfers, with 8bits/word, don't work without this patch. Signed-off-by: Jassi Brar Signed-off-by: Ben Dooks

ARM: S3C64XX: DMA: Unify callback functions for success/failure

2009-11-09T23:50:39+00:00

Replace s3c64xx_dma_tcirq and s3c64xx_dma_errirq with the common s3c64xx_dma_buffdone. Signed-off-by: Jassi Brar Signed-off-by: Ben Dooks

ARM: S3C64XX: DMA: Protect buffer pointers while manipulation

2009-11-09T23:50:39+00:00

Ensure the DMA buffer points are not updated from another source during the process of enquing a buffer. Signed-off-by: Jassi Brar [ben-linux@fluff.org: Updated patch comment] Signed-off-by: Ben Dooks

ARM: S3C64XX: DMA: Debugged alloc's with GFP_KERNEL flag in Intr context.

2009-09-15T23:50:06+00:00

s3c2410_dma_enqueue makes call to kzalloc and dma_pool_alloc with GFP_KERNEL flag set, this can be an issue for drivers, like I2S, which call s3c2410_dma_enqueue from dma-bufferdone callback. Change the flag GFP_KERNEL to GFP_ATOMIC to avoid any problems. Signed-Off-by: Jassi [ben-linux@fluff.org: Minor description edit and re-wrap] Signed-off-by: Ben Dooks

ARM: S3C64XX: DMA: 'size' argument of dma_pool_create

2009-09-15T23:50:06+00:00

Provide actual minimum(struct pl080s_lli) size of block to dma_pool_create call, instead of hardcoded 32 bytes. Signed-Off-by: Jassi Signed-off-by: Ben Dooks

[ARM] S3C64XX: Lower severity of DMA logging

2009-05-18T15:29:24+00:00

The message was missing a severity macro so pick pr_debug(). Signed-off-by: Mark Brown Signed-off-by: Ben Dooks
