2021-02-06media: v4l2-async: Improve v4l2_async_notifier_add_*_subdev() APILaurent Pinchart6-10/+10
The functions that add an async subdev to an async subdev notifier take as an argument the size of the container structure they need to allocate. This is error prone, as passing an invalid size will not be caught by the compiler. Wrap those functions in macros that take a container type instead of a size, and cast the returned pointer to the desired type. The compiler will catch mistakes if the incorrect type is passed to the macro, as the assignment types won't match.

2021-02-06media: v4l2-async: Clean v4l2_async_notifier_add_fwnode_remote_subdevEzequiel Garcia4-44/+20
Change v4l2_async_notifier_add_fwnode_remote_subdev semantics so it allocates the struct v4l2_async_subdev pointer. This makes the API consistent: the v4l2-async subdevice addition functions have now a unified usage model. This model is simpler, as it makes v4l2-async responsible for the allocation and release of the subdevice descriptor, and no longer something the driver has to worry about. On the user side, the change makes the API simpler for the drivers to use and less error-prone.

2021-01-27media: imx6-mipi-csi2: Call remote subdev get_mbus_config to get active lanesEzequiel Garcia1-12/+96
Currently, the CSI2 subdevice is using the data-lanes from the neareast endpoint to config the CSI2 lanes. While this may work, the proper way to configure the hardware is to obtain the remote subdevice in v4l2_async_notifier_operations.bound(), and then call get_mbus_config using the remote subdevice to get the active lanes.

Cedrus driver predates that, so it has implemented mechanism to check if all required controls are included in one request. Conform to specifications with removing that mechanism.

Cedrus reference list expects only bottom reference flag and only when interlaced frames are decoded. However, due to a bug in Cedrus check, exclusivity is not tested and that flag is set also for progressive references. That causes "jumpy" background with many videos.

Commit 86e02d07871c ("media: imx5/6/7: csi: Mark a bound video mux as a CSI mux") made an incorrect assumption that for imx7-media-csi, the bound subdev must always be a CSI mux. On i.MX6UL/i.MX6ULL there is no CSI mux at all, so do not return an error when the entity is not a video mux and assign the IMX_MEDIA_GRP_ID_CSI_MUX group id only when appropriate. This is the same approach as done in imx-media-csi.c and it fixes the csi probe regression on i.MX6UL. Tested on a imx6ull-evk board.

2021-01-12media: imx: Fix csc/scaler unregisterEzequiel Garcia1-4/+0
The csc/scaler device private struct is released by ipu_csc_scaler_video_device_release(), which can be called by video_unregister_device() if there are no users of the underlying struct video device. Therefore, the mutex can't be held when calling video_unregister_device() as its memory may be freed by it, leading to a kernel oops. Fortunately, the fix is quite simple as no locking is needed when calling video_unregister_device(): v4l2-core already has its own internal locking, and the structures are also properly refcounted.

git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC driver updates from Arnd Bergmann: "There are a couple of subsystems maintained by other people that merge their drivers through the SoC tree, those changes include: - The SCMI firmware framework gains support for sensor notifications and for controlling voltage domains. - A large update for the Tegra memory controller driver, integrating it better with the interconnect framework - The memory controller subsystem gains support for Mediatek MT8192 - The reset controller framework gains support for sharing pulsed resets For Soc specific drivers in drivers/soc, the main changes are - The Allwinner/sunxi MBUS gets a rework for the way it handles dma_map_ops and offsets between physical and dma address spaces. - An errata fix plus some cleanups for Freescale Layerscape SoCs - A cleanup for renesas drivers regarding MMIO accesses. - New SoC specific drivers for Mediatek MT8192 and MT8183 power domains - New SoC specific drivers for Aspeed AST2600 LPC bus control and SoC identification. - Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660 and SDX55. - A rework of the TI AM33xx 'genpd' power domain support to use information from DT instead of platform data - Support for TI AM64x SoCs - Allow building some Amlogic drivers as modules instead of built-in Finally, there are numerous cleanups and smaller bug fixes for Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips, Renesas, and Xilinx SoCs" * tag 'arm-soc-drivers-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (222 commits) soc: mediatek: mmsys: Specify HAS_IOMEM dependency for MTK_MMSYS firmware: xilinx: Properly align function parameter firmware: xilinx: Add a blank line after function declaration firmware: xilinx: Remove additional newline firmware: xilinx: Fix kernel-doc warnings firmware: xlnx-zynqmp: fix compilation warning soc: xilinx: vcu: add missing register NUM_CORE soc: xilinx: vcu: use vcu-settings syscon registers dt-bindings: soc: xlnx: extract xlnx, vcu-settings to separate binding soc: xilinx: vcu: drop useless success message clk: samsung: mark PM functions as __maybe_unused soc: samsung: exynos-chipid: initialize later - with arch_initcall soc: samsung: exynos-chipid: order list of SoCs by name memory: jz4780_nemc: Fix potential NULL dereference in jz4780_nemc_probe() memory: ti-emif-sram: only build for ARMv7 memory: tegra30: Support interconnect framework memory: tegra20: Support hardware versioning and clean up OPP table initialization dt-bindings: memory: tegra20-emc: Document opp-supported-hw property soc: rockchip: io-domain: Fix error return code in rockchip_iodomain_probe() reset-controller: ti: force the write operation when assert or deassert ...
2020-12-07media: cedrus: Make VP8 codec as capabilityJernej Skrabec3-9/+20
Commit 31d9b9ef8564 ("media: cedrus: Register all codecs as capability") makes separate capability flags for each codec. However, VP8 codec was merged at the same time as mentioned patch, so there is no capability flag for it. This patch adds capability flag for VP8 and enables it for all variants except for V3s.

2020-12-03media: uapi: move H264 stateless controls out of stagingEzequiel Garcia6-52/+52
The H.264 stateless 'uAPI' was staging and marked explicitly in the V4L2 specification that it will change and is unstable. Note that these control IDs were never exported as a public API, they were only defined in kernel-local headers (h264-ctrls.h). Now, the H264 stateless controls is ready to be part of the stable uAPI. While not too late, let's rename them and re-number their control IDs, moving them to the newly created stateless control class, and updating all the drivers accordingly.

2020-12-03media: Clean stateless control includesEzequiel Garcia1-3/+1
Avoid including h264-ctrls.h, vp8-ctrls.h, etc, and instead just include v4l2-ctrls.h which does the right thing. This is in preparation for moving the stateless controls out of staging, which will mean removing some of these headers.

The Rockchip Video Decoder used in RK3399 supports H.264 profiles from Baseline to High 4:2:2 up to Level 5.1, except for the Extended profile. Expose the V4L2_CID_MPEG_VIDEO_H264_PROFILE and the V4L2_CID_MPEG_VIDEO_H264_LEVEL control, so that userspace can query the driver for the list of supported profiles and level. For now, we don't expose 4:2:2 since the driver doesn't implement the required support.

2020-12-03media: cedrus: Add support for VP8 decodingJernej Skrabec8-1/+1037
VP8 in Cedrus shares same engine as H264. Note that it seems necessary to call bitstream parsing functions, to parse frame header, otherwise decoded image is garbage. This is contrary to what is driver supposed to do. However, values are not really used, so this might be acceptable. It's possible that bitstream parsing functions set some internal VPU state, which is later necessary for proper decoding. Biggest suspect is "VP8 probs update" trigger.
