dma: ipu: remove unnecessary platform_set_drvdata()

2013-08-25T09:07:13Z

The driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL. Signed-off-by: Jingoo Han Acked-by: Shawn Guo Signed-off-by: Vinod Koul

ipu_idmac: re-use dma_cookie_status()

2013-08-05T04:02:25Z

It's better to use generic dma_cookie_status() that allows user to get standard possible return codes independently of the DMAC driver in charge. Signed-off-by: Andy Shevchenko Acked-by: Shawn Guo Signed-off-by: Vinod Koul

dma: ipu: ipu_idmac: Fix section mismatch

2013-04-15T04:21:18Z

Since commit 84c1e63c12 (dma: Remove erroneous __exit and __exit_p() references) the following section mismatch happens: WARNING: drivers/built-in.o(.text+0x20f94): Section mismatch in reference from the function ipu_remove() to the function .exit.text:ipu_idmac_exit() The function ipu_remove() references a function in an exit section. Often the function ipu_idmac_exit() has valid usage outside the exit section and the fix is to remove the __exit annotation of ipu_idmac_exit. Remove the '__exit' annotation from ipu_idmac_exit in order to fix it. Signed-off-by: Fabio Estevam Acked-by: Maxin B. John Signed-off-by: Vinod Koul

dma: Remove erroneous exit and exit_p() references

2013-04-15T04:21:16Z

Removing the annotation with __exit and referencing with __exit_p() present in dma driver module remove hooks. Part of the __devexit and __devexit_p() purge. Signed-off-by: Maxin B. John Acked-by: Linus Walleij Signed-off-by: Vinod Koul

dma: ipu_idmac: reuse is_slave_direction helper

2013-01-12T13:07:22Z

The is_slave_direction helps to check if the transfer type is slave. Signed-off-by: Andy Shevchenko Reviewed-by: Viresh Kumar Cc: Guennadi Liakhovetski Signed-off-by: Vinod Koul

dma: ipu: Drop unused spinlock

2013-01-08T06:05:15Z

I was checking why this spinlock was never initialized, but it turns out it's not used anywhere, so we can drop it. Signed-off-by: Jean Delvare Cc: Vinod Koul Signed-off-by: Dan Williams

dma: ipu: rename mach/ipu.h to include/linux/dma/ipu-dma.h

2012-10-15T02:03:12Z

The header ipu.h really belongs to dma subsystem rather than imx platform. Rename it to ipu-dma.h and put it into include/linux/dma/.

dma: ipu: remove the use of ipu_platform_data

2012-07-01T13:57:43Z

The struct ipu_platform_data is used by platform code to pass MXC_IPU_IRQ_START to ipu-core driver. We can save it by having ipu-core driver call irq_alloc_descs to get the irq_base. Signed-off-by: Shawn Guo Acked-by: Vinod Koul Acked-by: Sascha Hauer Acked-by: Dong Aisheng

dmaengine: add context parameter to prep_slave_sg and prep_dma_cyclic

2012-03-21T13:50:23Z

Add context parameter to device_prep_slave_sg() and device_prep_dma_cyclic() interfaces to allow passing client/target specific information associated with the data transfer. Modify all affected DMA engine drivers. Signed-off-by: Alexandre Bounine Acked-by: Linus Walleij Acked-by: Felipe Balbi Signed-off-by: Vinod Koul
