media: Add MIPI CCI register access helper functions The CSI2 specification specifies a standard method to access camera sensor registers called "Camera Control Interface (CCI)". This uses either 8 or 16 bit (big-endian wire order) register addresses and supports 8, 16, 24 or 32 bit (big-endian wire order) register widths. Currently a lot of Linux camera sensor drivers all have their own custom helpers for this, often copy and pasted from other drivers. Add a set of generic helpers for this so that all sensor drivers can switch to a single common implementation. These helpers take an extra optional "int *err" function parameter, this can be used to chain a bunch of register accesses together with only a single error check at the end, rather than needing to error check each individual register access. The first failing call will set the contents of err to a non 0 value and all other calls will then become no-ops.

media: Kconfig: cleanup VIDEO_DEV dependencies media Kconfig has two entries associated to V4L API: VIDEO_DEV and VIDEO_V4L2. On Kernel 2.6.x, there were two V4L APIs, each one with its own flag. VIDEO_DEV were meant to: 1) enable Video4Linux and make its Kconfig options to appear; 2) it makes the Kernel build the V4L core. while VIDEO_V4L2 where used to distinguish between drivers that implement the newer API and drivers that implemented the former one. With time, such meaning changed, specially after the removal of all V4L version 1 drivers. At the current implementation, VIDEO_DEV only does (1): it enables the media options related to V4L, that now has: menu "Video4Linux options" visible if VIDEO_DEV source "drivers/media/v4l2-core/Kconfig" endmenu but it doesn't affect anymore the V4L core drivers. The rationale is that the V4L2 core has a "soft" dependency at the I2C bus, and now requires to select a number of other Kconfig options: config VIDEO_V4L2 tristate depends on (I2C || I2C=n) && VIDEO_DEV select RATIONAL select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE default (I2C || I2C=n) && VIDEO_DEV In the past, merging them would be tricky, but it seems that it is now possible to merge those symbols, in order to simplify V4L dependencies. Let's keep VIDEO_DEV, as this one is used on some make *defconfig configurations.

media: v4l: async, fwnode: Improve module organisation The V4L2 async framework is generally used with the V4L2 fwnode, which also depends on the former. There are a few exceptions but they are relatively few. At the same time there is a vast number of systems that need videodev module, but have no use for v4l2-async that's now part of videodev. In order to improve, split the v4l2-async into its own module. Selecting V4L2_FWNODE also selects V4L2_ASYNC. This also moves the initialisation of the debufs entries for async subdevs to loading of the v4l2-async module. The directory is named as "v4l2-async".

They allow both scanning for marker segment positions and later parsing the segments individually, as required by s5p-jpeg, as well as parsing all headers in one go, as required by coda-vpu. The frame header is always parsed, as basically all decoders are interested in width, height, and number of components. For convenience, the JPEG chroma subsampling factors are decoded into a v4l2_jpeg_chroma_subsampling enum. Only baseline and extended sequential DCT encoded JPEGs with 8-bit or 12-bit precision with up to four components are supported.

In most cases this other symbol is an architecture or platform specific symbol, or PCI. Generic symbols and drivers without platform dependencies keep their dependencies on HAS_DMA, to prevent compiling subsystems or drivers that cannot work anyway. This simplifies the dependencies, and allows to improve compile-testing.

Nobody maintains these drivers anymore. But unfortunately the v4l2-int-device API is used by out-of-tree drivers (MXC platform).

This patch moves v4l2-int-device and the two drivers that depend on it to staging in preparation for their removal.

[media] v4l: vb2-dma-contig: add support for dma_buf importing This patch makes changes for adding dma-contig as a dma_buf user. It provides function implementations for the {attach, detach, map, unmap}_dmabuf() mem_ops of DMABUF memory type.

[media] v4l: vb2: add support for shared buffer (dma_buf) This patch adds support for DMABUF memory type in videobuf2. It calls relevant APIs of dma_buf for v4l reqbuf / qbuf / dqbuf operations. For this version, the support is for videobuf2 as a user of the shared buffer; so the allocation of the buffer is done outside of V4L2. [A sample allocator of dma-buf shared buffer is given at [1]] [1]: Rob Clark's DRM: https://github.com/robclark/kernel-omap4/commits/drmplane-dmabuf [original work in the PoC for buffer sharing] Signed-off-by: Tomasz Stanislawski <t.stanislaws@samsung.com> Signed-off-by: Sumit Semwal <sumit.semwal@ti.com> Signed-off-by: Sumit Semwal <sumit.semwal@linaro.org> Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Tested-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
