The raw Sony IR decoder decodes 15bit messages slightly incorrectly. To decode the function number, it shifts the bits right by 7 so that the function is in bits 7:1, masks with 0xFD (0b11111101), and does an 8 bit reverse so it ends up in bits 6:0. The mask should be 0xFE to correspond with bits 7:1 (0b11111110). The old mask had the effect of dropping the MSB of the function number from bit 6, and leaving the LSB of the device number in bit 7.

In driver ivtv, there is a mismatch between the type of the radio module parameter and the storage variable, which leads to the following warning: CC [M] drivers/media/video/ivtv/ivtv-driver.o drivers/media/video/ivtv/ivtv-driver.c: In function ‘__check_radio’: drivers/media/video/ivtv/ivtv-driver.c:142: warning: return from incompatible pointer type drivers/media/video/ivtv/ivtv-driver.c: At top level: drivers/media/video/ivtv/ivtv-driver.c:142: warning: initialization from incompatible pointer type Signed-off-by:

The code was unnecessarily complex, introducing a hdl_out handler that was not needed. Instead just add the controls to the cxhdl.hdl handler directly. Signed-off-by:

Hans Verkuil authored
Currently v4l2_ctrl_add_handler adds only the controls that are owned by the handler. This is wrong. Instead all controls, whether owned or not, should be added. This is also implied by the v4l2-controls.txt documentation and it is clearly the right thing to do. The only reason this was never noticed before is because we never did this. Only recent changes in ivtv made this error visible because there a third handler layer was added (handler A inherits from handler B which inherits from C, D and E). Without this change handler A only sees the controls owned by handler B and the controls from C, D and E are missing. Signed-off-by:

I don't have this hardware and I don't know the subsystem very well. So please review this patch carefully. The original code definitely looks buggy though. Sparse complains about some endian bugs where little endian bugs are treated as cpu endian. Signed-off-by:

"f" wasn't checked consistently, so static checkers complain. This function is always called with a valid "f" pointer, so I have removed the check. Also the indenting was messed up. Signed-off-by:

Raw IR events are passed to the raw event thread through a kfifo. The size of the event struct is 12 bytes, and space for 512 events is reserved in the kfifo (6144 bytes), however this is rounded down to 4096 bytes (the next power of 2) by __kfifo_alloc(). 4096 bytes is not divisible by 12 therefore if the fifo fills up a third of a record will be written in the end of the kfifo by ir_raw_event_store() because the recsize of the fifo is 0 (it doesn't have records). When this is read by ir_raw_event_thread() a corrupted or partial record will be read, and in the case of a partial record the BUG_ON(retval != sizeof(ev)) gets hit too. According to samples/kfifo/record-example.c struct kfifo_rec_ptr_1 can handle records of a length between 0 and 255 bytes, so change struct ir_raw_event_ctrl to use that instead of struct kfifo.

The way discard buffer was previously handled lead to possible races that made a buffer that was not yet ready to be overwritten by new video data. This is easily detected at 25fps just adding "#define DEBUG" to enable the "memset" check and seeing how the image is corrupted. A new "discard" queue and two discard buffers have been added to make them flow trough the pipeline of queues and thus provide suitable event ordering. Signed-off-by:

Add "start_stream" and "stop_stream" callback in order to enable and disable the eMMa-PrP properly and save CPU usage avoiding IRQs when the device is not streaming. This also makes the driver return 0 as the sequence number of the first frame. Signed-off-by:

The i.MX27 DMA support was introduced with the initial commit of this driver and originally created by me. However, I never got this stable due to the racy DMA engine and used the EMMA engine instead. As the DMA support is most probably unused and broken in its current state, remove it. EMMA becomes the only supported mode on i.MX27. This also helps us get rid of another user of the legacy i.MX DMA support and remove the dependency on ARCH_MX* macros as these are scheduled for removal. Signed-off-by:
