The AVerMedia CE310B is a simple composite + S-Video + stereo audio capture card, and uses only the CX23888 to perform all of these functions. I've tested both video inputs and the audio interface and confirmed that they're all working. However, there are some issues: * Sometimes when I switch inputs the video signal turns black and can't be recovered until the system is rebooted. I haven't been able to determine the cause of this behavior, nor have I found a solution to fix it or any workarounds other than rebooting. * The card sometimes seems to have trouble syncing to the video signal, and some of the VBI data appears as noise at the top of the frame, but I assume that to be a result of my very noisy RF environment and the card's unshielded input traces rather than a configuration issue.

Hans Verkuil authored
Currently wait_event_interruptible_timeout is called in cec_thread_func() when adap->transmitting is set. But if the adapter is unconfigured while transmitting, then adap->transmitting is set to NULL. But the hardware is still actually transmitting the message, and that's indicated by adap->transmit_in_progress and we should wait until that is finished or times out before transmitting new messages. As the original commit says: adap->transmitting is the userspace view, adap->transmit_in_progress reflects the hardware state. However, if adap->transmitting is NULL and adap->transmit_in_progress is true, then wait_event_interruptible is called (no timeout), which can get stuck indefinitely if the CEC driver is flaky and never marks the transmit-in-progress as 'done'. So test against transmit_in_progress when deciding whether to use the timeout variant or not, instead of testing against adap->transmitting. Signed-off-by:

WARN if transmit_queue_sz is 0 but do not decrement it. The CEC adapter will become unresponsive if it goes below 0 since then it thinks there are 4 billion messages in the queue. Obviously this should not happen, but a driver bug could cause this. Signed-off-by:

Some messages are allowed to be a broadcast message in CEC 2.0 only, and should be ignored by CEC 1.4 devices. Unfortunately, the check was wrong, causing such messages to be marked as invalid under CEC 2.0. Signed-off-by:

Currently we were using an arbitrarily small maximum resolution mostly based on available sensor capabilities. However the hardware DMA limits are much higher than the statically define maximum resolution we were using. There we rework the boundary check code to handle the maximum width and height based on the maximum line width in bytes and re-calculating the pixel width based on the given pixel format.

The pixel processing unit was hard coded to only handle 8 bits per pixel from input to output. We now add handling for 10, 12 and 16 bits per pixel at the source and setting the in-memory size (i.e. container size) to 16 bits for these 3 cases. Signed-off-by:

The current method to calculate the ddr clk period is wrong. Therefore the ths_term calculation is incorrect. Also it was wrongly assumed that the ths_settle parameter was based on the control clock instead of the pixel clock. Since the DPHY can tolerate quite a bit a of variation, capture was still mostly working with the 2 tested modes when the pixel clock was close to the control clock (i.e. 96 Mhz). But it would quickly stops working when using different modes or when customers used different sensors altogether. Calculating the DDRClk period needs to take into account the pixel bit width and the number of active data lanes. Based on the latest technical reference manual these parameters should now be calculated as follows: THS_TERM: Programmed value = floor(20 ns/DDRClk period) THS_SETTLE: Programmed value = floor(105 ns/DDRClk period) + 4 Also originally 'depth' was used to represent the number of bits a pixel would use once stored in memory (i.e. the container size). To accurately calculate the THS_* parameters we need to use the actual number of bits per pixels coming in from the sensor. So we are renaming 'depth' to 'bpp' (bits per pixels) and update the format table to show the actual number of bits per pixel being received. The "container" size will be derived from the "bpp" value. Signed-off-by:

When setting DMA for video capture from CSI channel, if the DMA size is not given, it ends up writing as much data as sent by the camera. This may lead to overwriting the buffers causing memory corruption. Observed green lines on the default framebuffer. Restrict the DMA to maximum height as specified in the S_FMT ioctl. Signed-off-by:

First this patch adds a method to access the CTRL_CORE_CAMERRX_CONTROL register to use the syscon mechanism. For backward compatibility we also handle using the existing camerrx_control "reg" entry if a syscon node is not found. In addition the register bit layout for the CTRL_CORE_CAMERRX_CONTROL changes depending on the device. In order to support this we need to use a register access scheme based on data configuration instead of using static macro. In this case we make use of the regmap facility and create data set based on the various device and phy available. Signed-off-by:
