White balance computed gains can overflow above the 13 bits hardware coefficient that can be used, in some specific scenarios like a subexposure from the sensor when the image is mostly black. In this case the computed gain has to be clamped to the maximum value allowed by the hardware. Signed-off-by:

The bytesperline field of the pixfmt should be only for the first plane in case of planar formats like YUV420 or YUV422. The bytesperline is used by the driver to compute the framesize. We have to report a different bpp (bytes per pixel) to v4l2 in bytesperline than the actual bpp. For example for YUV420, the real bpp is 12, but the first plane has only 8 bpp. Thus we report a bytesperline 8*width instead of 12*width. However, for real framezise we have to compute 12*width*height. Hence added a new variable to hold this information and to correctly compute the frame size. Signed-off-by:

The ISC supports a full broad range of frame sizes. Until now, the subdevice was queried for possible frame sizes and these were reported to the user space. However, the ISC should not care about which frame sizes the subdev supports, as long as this frame size is supported. Thus, report a continuous range from smallest frame size up to the max resolution. Signed-off-by:

VIDIOC_ENUM_FRAMEINTERVALS is not recommended for a top video driver. The frame rate is defined by the sensor subdevice, thus it can be queried directly by anyone interested in the frame intervals. Signed-off-by:

Add bindings documentation for Microchip CSI2 Demultiplexer controller. CSI2DC is a demultiplexer from Synopsys IDI interface specification to parallel interface connection or direct memory access. CSI2DC can also act as a parallel bypass from a parallel sensor to the image sensor controller/interface. Signed-off-by:

Prior to submitting a transfer to the DMA, the client should first check the capabilities of the DMA channel in term of maximum of each segment. This is given by the max_sg_burst value reported by dma_get_slave_caps API. Based on that, if the transfer is larger than what can be handled by the DMA channel, we split the transfer into several scatterlist elements.

V4L2_PIX_FMT_NV12 requires num_planes equals to 1, V4L2_PIX_FMT_NV12M requires num_planes equals to 2. and mxc-jpeg supports 2 planes for nv12, so we should use 4L2_PIX_FMT_NV12M instead of V4L2_PIX_FMT_NV12, otherwise it will confuses gstreamer and prevent encoding and decoding. Signed-off-by:

The driver allocates and registers two platform device structures during probe, but the devices were never deregistered on driver unbind. This results in a use-after-free on driver unbind as the device structures were allocated using devres and would be freed by driver core when remove() returns. Fix this by adding the missing deregistration calls to the remove() callback and failing probe on registration errors. Note that the platform device structures must be freed using a proper release callback to avoid leaking associated resources like device names.

during system resume, interconnect bandwidth would currently be requested even though the device is runtime suspended. This leaves the system in an unbalanced state. Fix that by only doing that in runtimem pm and splitting up runtime and system suspend to be a more readable: imx8mq_mipi_csi_pm_*() does the generic things called from system- and runtime functions that each do specific things on top.

The place where this register writel() that masks one interrupt is placed does not guarantee that the device is powered so that's not allowed. Moreover imx8mq_mipi_csi_start_stream() masks the interrupt anyway so the write is not even needed. Remove it as this is a mistake that slipped in with the driver.

DST_QUEUE_OFF_BASE is applied to offset/mem_offset on MMAP capture buffers only for the VIDIOC_QUERYBUF ioctl, while the userspace fields (including offset/mem_offset) are filled in for VIDIOC_{QUERY,PREPARE,Q,DQ}BUF ioctls. This leads to differences in the values presented to userspace. If userspace attempts to mmap the capture buffer directly using values from DQBUF, it will fail. Move the code that applies the magic offset into a helper, and call that helper from all four ioctl entry points.

The error injection controls that test wrap-around sequence and timestamp counters were partially broken. Add a menu option for 64 or 32 bit signed timestamp wrapping. Prevent the timestamp from wrapping around before the device can be tested. Remove the sequence count from the timestamp calculation so that sequence wrapping does not interfere with the timestamp. Add consistent time and sequence wrapping to sdr and touch devices. Signed-off-by:

The sm8250 CAMSS CSID depends on the VFE it is attached to being powered on and clocked prior to taking the CSID out of reset. It is possible to open just the CSID subdev from libcamera and attempt to bring the CSID block up. If we do not first bring up the VFE the CSID will fail to come out of reset. Tested-by:

Downstream makes some pretty explicit comments about voting for bus bandwidth prior to camcc_camnoc_axi_clk_src. Working with camx downstream also shows that the bandwidth vote is required to get that root clock working. Add a simple mechanism to declare set and unset named NOCs. Whereas the objective is to enable the sm8250 specifically the code has been implemented to allow setting of whatever NOCs different SoCs using this driver may require. Tested-by:

The Titan 480 camss found on SM8250 has 6 CSIPHY and 4 VFE/CSID. CSID is compatible with the Titan 170 CSID, but the Titan 480 CSID are inside the VFE region (between the "top" and "bus" registers), so a workaround is added to avoid ioremap failure.
