The chip can be configured to output data transitions on the rising or falling edge of PIXCLK (Datasheet R58:1[9]), default is on the falling edge. Parsing the fw-node is made in a subfunction to bundle all (future) dt-parsing / fw-parsing stuff. [m.grzeschik@pengutronix.de: Fix inverting clock. INV_PIX_CLOCK bit is set per default. Set bit to 0 (enable mask bit without value) to enable falling edge sampling.] [m.felsch@pengutronix.de: use fwnode helpers] [m.felsch@pengutronix.de: mv fw parsing into own function] [m.felsch@pengutronix.de: adapt commit msg] [sakari.ailus@linux.intel.com: V4L2 API usage changes to compile on media tree master] Signed-off-by:

This patch implements the framerate selection using the skipping and readout power-modi features. The power-modi cut the framerate by half and each context has an independent selection bit. The same applies to the 2x skipping feature. Signed-off-by:

Currently set_fmt don't care about the streaming status, so the format can be changed during streaming. This can lead into wrong behaviours. Check if the device is already streaming and return -EBUSY to avoid wrong behaviours. Signed-off-by:

On a imx6q-wandboard the following warnings are observed: [ 4.327794] video-mux 20e0000.iomuxc-gpr:ipu1_csi0_mux: bad remote port parent [ 4.336118] video-mux 20e0000.iomuxc-gpr:ipu2_csi1_mux: bad remote port parent As explained by Philipp Zabel: "There are empty endpoint nodes (without remote-endpoint property) labeled ipu1_csi[01]_mux_from_parallel_sensor in the i.MX6 device trees for board DT implementers' convenience. See commit 2539f517 ("ARM: dts: imx6qdl: Add video multiplexers, mipi_csi, and their connections")." So demote the warning to debug level and make the wording a bit less misleading. Suggested-by:

The io.h was still included twice. Having a large number of includes like that unsorted is likely the reason why we ended by having 3 includes of io.h and two includes of interrupt.h at the first place. So, let's reorder the includes on alphabetic order. That would make easier to maintain it. Fixes: 12645e06 ("media: ddbridge: remove some duplicated include file") Signed-off-by:

CXD2837ER handled in DVB_CXD2841ER module but it's has a lack of control. So slave demod has to be reseted by GPIO0 before detecting to woke up CXD2837ER. Signed-off-by:

We have both uvc_init_video() and uvc_video_init() calls which can be quite confusing to determine the process for each. Now that video uvc_video_enable() has been renamed to uvc_video_start_streaming(), adapt these calls to suit the new flow. Rename uvc_init_video() to uvc_video_start_transfer() and uvc_uninit_video() to uvc_video_stop_transfer(). Signed-off-by:

uvc_video_enable() is used both to start and stop the video stream object, however the single function entry point shares no code between the two operations. Split the function into two distinct calls, and rename to uvc_video_start_streaming() and uvc_video_stop_streaming() as appropriate. Signed-off-by:

Newer high definition cameras, and cameras with multiple lenses such as the range of stereo-vision cameras now available have ever increasing data rates. The inclusion of a variable length packet header in URB packets mean that we must memcpy the frame data out to our destination 'manually'. This can result in data rates of up to 2 gigabits per second being processed. To improve efficiency, and maximise throughput, handle the URB decode processing through a work queue to move it from interrupt context, and allow multiple processors to work on URBs in parallel.

The streaming object is a key part of handling the UVC device. Although not critical, we are currently missing a call to destroy the mutex on clean up paths, and we are due to extend the objects complexity in the near future. Facilitate easy management of a stream object by creating a pair of functions to handle creating and destroying the allocation. The new uvc_stream_delete() function also performs the missing mutex_destroy() operation. Previously a failed streaming object allocation would cause uvc_parse_streaming() to return -EINVAL, which is inappropriate. If the constructor failes, we will instead return -ENOMEM. While we're here, fix the trivial spelling error in the function banner of uvc_delete(). Signed-off-by:

The buffer queue interface currently operates sequentially, processing buffers after they have fully completed. In preparation for supporting parallel tasks operating on the buffers, we will need to support buffers being processed on multiple CPUs. Adapt the uvc_queue_next_buffer() such that a reference count tracks the active use of the buffer, returning the buffer to the VB2 stack at completion. Signed-off-by:

Both uvc_start_streaming(), and uvc_stop_streaming() are called from userspace context, with interrupts enabled. As such, they do not need to save the IRQ state, and can use spin_lock_irq() and spin_unlock_irq() respectively. Signed-off-by:

The URB completion operation obtains the current buffer by reading directly into the queue internal interface. Protect this queue abstraction by providing a helper uvc_queue_get_current_buffer() which can be used by both the decode task, and the uvc_queue_next_buffer() functions. Signed-off-by:

We currently store three separate arrays for each URB reference we hold. Objectify the data needed to track URBs into a single uvc_urb structure, allowing better object management and tracking of the URB. All accesses to the data pointers through stream, are converted to use a uvc_urb pointer for consistency. Signed-off-by:
