The dma_queue list is accessed by both the interrupt handler and by normal code. It needs to be protected by a lock to prevent possible list corruption. Corruption has been observed in 'real-life' conditions. Adding this lock made it go away. Signed-off-by:

In case of error, the function vb2_dma_contig_init_ctx() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). dpatch engine is used to auto generate this patch. (https://github.com/weiyj/dpatch) Signed-off-by:

The v4l2_subdev_call() call returns -ENODEV when subdev is null and -ENOIOCTLCMD wnen no icotl is present. This patch fixes the return type check for v4l2_subdev_call(). The pattern E == C1 && E == C2 is always false. This patch fix this according to the assumption that && should be ||. dpatch engine is used to auto generate this patch.

v4l2_subdev_link_validate_get_format() retrieves the remote pad format depending on the entity type and prints a warning if the entity type is not supported. The type check doesn't take the subtype into account, and thus always prints a warning for device node types, even when supported. Fix it. Signed-off-by:

Set "y_skip_top" to zero and revise comment as I do not see this line corruption on two different mt9v022 setups. The first read-out line is perfectly fine. Add mt9v022 platform data configuring y_skip_top for platforms that have issues with the first read-out line. Set y_skip_top to 1 for pcm990 board. Signed-off-by:

Some camera systems cannot operate mt9v022 in normal mode and use only the snapshot mode. The TechNote for mt9v022 (TN0960) and mt9v024 (TN-09-225) describes required register settings when configuring the snapshot operation. The snapshot mode requires that certain automatic functions of the image sensor should be disabled or set to fixed values. According to the TechNote bit 2 and bit 9 in the register 0x20 must be set in snapshot mode and unset for normal operation. This applies for mt9v022 Rev.3 and mt9v024. Add required reg. 0x20 settings dependent on sensor chip version. Signed-off-by:

Add controls for horizontal and vertical blanking. Also add an error message for case that the control handler init failed. Since setting the blanking registers is done by controls now, we shouldn't change these registers outside of the control function. Use v4l2_ctrl_s_ctrl() to set them. Signed-off-by:

The mx1_camera driver has been broken for a few release cycles since commit 6bd08127 (dmaengine: imx-dma: merge old dma-v1.c with imx-dma.c). It seems there is no one even compile tested it since then, as doing so will end up with the following error. CC drivers/media/platform/soc_camera/mx1_camera.o In file included from drivers/media/platform/soc_camera/mx1_camera.c:44:0: arch/arm/mach-imx/include/mach/dma-mx1-mx2.h:8:25: fatal error: mach/dma-v1.h: No such file or directory It seems there is no one being interested in bringing it back to work [1] so far. Let's mark it BROKEN. [1] https://lkml.org/lkml/2012/2/9/171Signed-off-by:

The winbond hardware has a counter for leading edges, which increases as they are received. As we read raw IR from a fifo in an interrupt handler, we cannot correlate them to specific IR pulses so we simply count all pulses and edges until we go idle and disable the receiver. Signed-off-by:

The receiver is never disabled by idle mode since rxstate never gets set to RXSTATE_ACTIVE, so we keep on getting interrupts after the first IR activity ends. Note that ir_raw_event_reset() already calls ir_raw_event_handle(). Signed-off-by:
