Fix the assigned type of mem2mem buffer handling API. Namely, these functions: v4l2_m2m_next_buf v4l2_m2m_last_buf v4l2_m2m_buf_remove v4l2_m2m_next_src_buf v4l2_m2m_next_dst_buf v4l2_m2m_last_src_buf v4l2_m2m_last_dst_buf v4l2_m2m_src_buf_remove v4l2_m2m_dst_buf_remove return a struct vb2_v4l2_buffer, and not a struct vb2_buffer. Fixing this is necessary to fix the mem2mem buffer handling API, changing the return to the correct struct vb2_v4l2_buffer instead of a void pointer. Signed-off-by:

The CSI controller can take raw data from the data bus and output it directly to capture buffers. This can be used to support the JPEG media bus format. While the controller can report minimum and maximum bytes per line, it has no way to report how many lines were captured in the last frame. Thus, even when the on-bus data is framed correctly, we have no way to accertain the actual amount of data captured, unless we scan the buffer for JPEG EOI markers, or sequential zeros. For now we leave bytesused alone, and leave it up to userspace applications to parse the data. Signed-off-by:

The CSI controller can take raw data from the data bus and output RGB565 format. The controller does not distinguish between RGB565 LE and BE. Instead this is determined by the media bus format, i.e. the format or order the sensor is sending data in. Signed-off-by:

max_register is currently set to 0x1000. This is beyond the mapped address range of the hardware, so attempts to dump the regmap from debugfs would trigger a kernel exception. Furthermore, the useful registers only occupy a small section at the beginning of the full range. Change the value to 0x9c, the last known register on the V3s and H3. On the A31, the register range is extended to support additional capture channels. Since this is not yet supported, ignore it for now.

The uvc driver uses this function to fill in bus_info for VIDIOC_QUERYCAP, so use the same function when filling in the bus_info for the media device. The current implementation only fills in part of the info. E.g. if the full bus_info is usb-0000:01:00.0-1.4.2, then the media bus_info only has 1.4.2. Signed-off-by:

CSI block in Allwinner A64 has similar features as like in H3, but the default CSI_SCLK rate cannot work properly to drive the connected sensor interface. The tested mod cock rate is 300 MHz and BSP vfe media driver is also using the same rate. Unfortunately there is no valid information about clock rate in manual or any other sources except the BSP driver. so more faith on BSP code, because same has tested in mainline. So, add support for A64 CSI block by setting updated mod clock rate. Signed-off-by:

The extended-controls.rst file had become too big. Split it up: each control class reference gets its own rst file, and this file just describes the Extended Control API. Each control class reference is also moved up one level into the table of contents to make it easier to find e.g. the codec control reference. Finally I rearranged the order so that all camera-related control classes are grouped together, ditto for codec/jpeg and fm-rx/tx. The ext-ctrls-codec.rst is still pretty big and it is a candidate to split up further in the future, possibly per codec. Signed-off-by:

If a stream is stopped, or if a USERPTR/DMABUF buffer is queued backed by a different user address or dmabuf fd, then the timestamp should be skipped by vb2_find_timestamp since the memory it refers to is no longer valid. So keep track of a 'copied_timestamp' state: it is set when the timestamp is copied from an output to a capture buffer, and is cleared when it is no longer valid. Signed-off-by:

The formats added in this patch include: V4L2_PIX_FMT_AYUV32 V4L2_PIX_FMT_XYUV32 V4L2_PIX_FMT_VUYA32 V4L2_PIX_FMT_VUYX32 These formats enable the trasmission of alpha channel data to other drivers and userspace applications in addition to YUV data. For example, buffers generated by drivers in one of these formats can be used by the Weston compositor to display as a texture or flipped directly onto the overlay planes with the help of a DRM driver.

This patch makes the SoC camera framework as well as effectively the few remaining sensor drivers depend on BROKEN, rendering it uncompileable without changes in Kconfig.
