This patch changes the order of operations during stream on call. Now the buffers are first queued to the driver and then the start_streaming method is called. This resolves the most common case when the driver needs to know buffer addresses to enable dma engine and start streaming. Additional parameter to start_streaming method have been added to simplify drivers code. The driver are now obliged to check if the number of queued buffers is high enough to enable hardware streaming. If not - it can return an error. In such case all the buffers that have been pre-queued are invalidated. This patch also updates all videobuf2 clients to work properly with the changed order of operations. Signed-off-by:

Use the correct 'dma_addr' name for the buffer address. 'paddr' suggested that this is the physical address in system memory. For most ARM platforms these two are the same, but this is not a generic rule. 'dma_addr' will also point better to dma-mapping api. Signed-off-by:

Plane sizes array was declared as unsigned long[], while unsigned int is more than enough for storing size of the video buffer. This patch reduces the size of the array by definiting it as unsigned int[]. Reported-by:

MAPPED flag was set for the buffer only if all it's planes were mapped and relied on a simple mapping counter. This assumption is really bogus, especially because the buffers may be mapped multiple times. Also the meaning of this flag for muliplane buffers was not really useful. This patch fixes this issue by setting the MAPPED flag for the buffer if any of it's planes is in use (what means that has been mapped at least once), so MAPPED flag can be used as 'in_use' indicator.

Videobuf2 accepted any userptr buffer without verifying if its size is large enough to store the video data from the driver. The driver reports the minimal size of video data once in queue_setup and expects that videobuf2 provides buffers that match these requirements. This patch adds the required check. Reported-by:
