Currently a call to snd_card_new that fails will set card with a NULL pointer, this causes a null pointer dereference on the error cleanup path when card it passed to snd_card_free.

Modify the scaler subdevice to accept setting the resolution of the source pad (previously the source resolution would always be 3 times the sink for both dimensions). Now any resolution can be set at src (even smaller ones) and the sink video will be scaled to match it.

When adding an internal scratch buffer to improve buffer handling when stopping it was also erroneously used when syncing at capture start. This led to that the first three buffers captured were always dropped as they were captured in the scratch buffer instead of in a buffer provided by the user. Allow the hardware to be given user provided buffers when preparing for capture in the stopped state. This still allows the driver to sync with the hardware and always completes the buffers to user-space in the correct order as no buffers are completed before the sync is complete. This change improves the driver as buffers are completed and given to the user three frames earlier than before. The change also fixes a warning produced by v4l2-compliance, warn: v4l2-test-buffers.cpp(448): got sequence number 3, expected 0 [hverkuil: fixed some typos in the Subject and the log message] Signed-off-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

MLX90640 should ideally be working without a frame skip. In short, if a frame is skipped, then half of a frame loses correction information, having no way to retrieve its original compensation. This patch improves the timing in three ways: 1) Replaced schedule_timeout_interruptible() to usleep_range() The former "only ensures that it will sleep for at least schedule_delay (if not interrupted)", as pointed out by mchehab. As a result, the frame rate could lag behind than the actual capability of the hardware (Raspberry Pi would show a few Hz slower than set value) 2) Calculation based on us, not jiffies Jiffies usually has resolution of 100Hz, and possibly even cruder. MLX90640 can go up to 64Hz frame rate, which does not make sense to calculate the interval with aforementioned resolution. 3) Interval calculation based on the last frame's end time Using the start time of the current frame will probably make tiny bit of drift every time. This made more sense when I didn't realize 1), but it still makes sense without adding virtually any complexity, so this stays in.

This patch lets user-space request a non-coherent memory allocation during CREATE_BUFS and REQBUFS ioctl calls. = CREATE_BUFS struct v4l2_create_buffers has seven 4-byte reserved areas, so reserved[0] is renamed to ->flags. The struct, thus, now has six reserved 4-byte regions. = CREATE_BUFS32 struct v4l2_create_buffers32 has seven 4-byte reserved areas, so reserved[0] is renamed to ->flags. The struct, thus, now has six reserved 4-byte regions. = REQBUFS We use one byte of a 4 byte ->reserved[1] member of struct v4l2_requestbuffers. The struct, thus, now has reserved 3 bytes.

This moves cache hints handling from the videobuf2 core down to the allocator's level, because allocators do the sync/flush caches eventually and may take better decisions. Besides, allocators already decide whether cache sync/flush should be done or can be skipped. This patch moves the scattered buffer cache sync logic to one common place.

With the new DMA API we need an extension of the videobuf2 API. Previously, videobuf2 core would set the non-coherent DMA bit in the vb2_queue dma_attr field (if user-space would pass a corresponding memory hint); the vb2 core then would pass the vb2_queue dma_attrs to the vb2 allocators. The vb2 allocator would use the queue's dma_attr and the DMA API would allocate either coherent or non-coherent memory. But we cannot do this anymore, since there is no corresponding DMA attr flag and, hence, there is no way for the allocator to become aware of what type of allocation user-space has requested. So we need to pass more context from videobuf2 core to the allocators. Fix this by changing the call_ptr_memop() macro to pass the vb2 pointer to the corresponding op callbacks.

Currently, the vivid emulation of cec message transmission does not force adapters to wait until the cec bus has been signal-free for a certain number of bit periods before transmitting or re-transmitting a message. Without enforcing the signal-free time requirements, adapters do not share the bus very well and some messages are sent too quickly while other messages are lost. By emulating a signal-free time and forcing adapters to wait their turn to transmit, the vivid emulation of cec transmission is much more reliable.

A successful 'mxc_jpeg_attach_pm_domains()' call should be balanced by a corresponding 'mxc_jpeg_detach_pm_domains()' call in the error handling path of the probe, as already done in the remove function. Update the error handling path accordingly.
