2015-11-19[media] v4l: omap_vout: Don't free buffers if they haven't been allocatedLaurent Pinchart
The VRFB buffers are freed when the device is closed even if they haven't been allocated by a call to VIDIOC_REQBUFS, resulting in a crash. Fix it by not trying to free buffers that are not allocated. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2015-03-03[media] media: omap/omap_vout: fix type of input members to ↵Lad, Prabhakar
omap_vout_setup_vrfb_bufs() the declaration for omap_vout_setup_vrfb_bufs() said it needed 'u32 static_vrfb_allocation' but definition took 'bool static_vrfb_allocation', this patch fixes the declaration so that it matches with the definition and pass a bool instead of int to the call, also included omap_vout_vrfb.h in omap_vout_vrfb.c file so that sparse doesn't complain of making omap_vout_setup_vrfb_bufs() as static function.

2014-09-03[media] omap: simplify test logicMauro Carvalho Chehab
instead of testing bools if they are false or true, just use if (!foo) or if (foo). That makes the code easier to read and shorter. Also, properly initialize booleans with true or false. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-02-28[media] omap_vout: avoid sleep_on raceArnd Bergmann
sleep_on and its variants are broken and going away soon. This changes the omap vout driver to use wait_event_interruptible_timeout instead, which fixes potential race where the dma is complete before we schedule.

2012-11-30ARM: OMAP: Move plat-omap/dma-omap.h to include/linux/omap-dma.hTony Lindgren
Based on earlier discussions[1] we attempted to find a suitable location for the omap DMA header in commit 2b6c4e73 (ARM: OMAP: DMA: Move plat/dma.h to plat-omap/dma-omap.h) until the conversion to dmaengine is complete. Unfortunately that was before I was able to try to test compile of the ARM multiplatform builds for omap2+, and the end result was not very good. So I'm creating yet another all over the place patch to cut the last dependency for building omap2+ for ARM multiplatform. After this, we have finally removed the driver dependencies to the arch/arm code, except for few drivers that are being worked on. The other option was to make the <plat-omap/dma-omap.h> path to work, but we'd have to add some new header directory to for multiplatform builds. Or we would have to manually include arch/arm/plat-omap/include again from arch/arm/Makefile for omap2+. Neither of these alternatives sound appealing as they will likely lead addition of various other headers exposed to the drivers, which we want to avoid for the multiplatform kernels. Since we already have a minimal include/linux/omap-dma.h, let's just use that instead and add a note to it to not use the custom omap DMA functions any longer where possible. Note that converting omap DMA to dmaengine depends on dmaengine supporting automatically incrementing the FIFO address at the device end, and converting all the remaining legacy drivers. So it's going to be few more merge windows.

Some of the omap1 dma channel definitions are used by some drivers. For moving omap1 dma channel definitions to mach-omap1/, the used ones should be defined locally to driver. Driver can eliminate it by using DT, platform data, or IORESOURCE_DMA.
