Instead of filling in the struct v4l2_capability device_caps field, fill in the struct video_device device_caps field. That way the V4L2 core knows what the capabilities of the video device are. But this only really works if all drivers use this, so convert this touchscreen driver accordingly. Signed-off-by:

Dynamically allocate clocks and move clock names out of struct hantro_variant. This lifts the four clock limit and allows to use ARRAY_SIZE() to fill .num_clocks to reduce the risk of mismatches. Signed-off-by:

The i.MX8MQ bindings will use different IRQ names ("g1" instead of "vdpu", and "g2"), so make them configurable. This also allows to register more than two IRQs, which will be required for i.MX8MM support later (it will add "h1" instead of "vepu"). Signed-off-by: -

It seems that on i.MX8MQ the power domain controller does not propagate resets to the VPU cores on resume. Add a callback to allow implementing manual reset of the VPU cores after ungating the power domain. Signed-off-by:

Rename the driver and all relevant identifiers from Rockchip to Hantro, as other Hantro IP based VPU implementations can be supported by the same driver. The RK3288 decoder is Hantro G1 based, the encoder is Hantro H1. This patch just renames, no functional changes. Signed-off-by:

uvcvideo creates a debugfs directory based on the device bus number and device number. If a device contains more than one uvc function, the creation of the second and following debugfs directories will fail and print an info message like this: "uvcvideo: Unable to create debugfs 3-2 directory." This patch includes the uvc streaming interface number in the debugfs directory name, to make sure it is unique. The directory name format is changed from "<busnum>-<devnum>" to "<busnum>-<devnum>-<intfnum>" Signed-off-by:

Correctly handle stopping and restarting the encoder, keeping track of the stop and drain states. In addition it adds correct handling of corner cases, allowing v4l2-compliance to pass. Unfortunately, the code is getting to be quite complicated, so we need to work on better codec support in v4l2-mem2mem.c to simplify drivers. Signed-off-by:

After a resolution change is detected, q_data->sizeimage is updated to the new format, but buf_prepare is still draining buffers that need to use the old pre-resolution-change value. So store the sizeimage value in q_data->vb2_sizeimage in queue_setup and use that in buf_prepare. Signed-off-by:

Setting the encoder output format to e.g. 1920x1080 will set the crop rectangle to 1920x1088, the coded resolution to 1920x1088 and the capture coded resolution and sizeimage to 1920x1088 as well. Note that this might change, since the encoder spec is still in flux with respect to how this should behave. Signed-off-by:

Amlogic SoCs feature a powerful video decoder unit able to decode many formats, with a performance of usually up to 4k60. This is a driver for this IP that is based around the v4l2 m2m framework. It features decoding for: - MPEG 1 - MPEG 2 Supported SoCs are: GXBB (S905), GXL (S905X/W/D), GXM (S912) There is also a hardware bitstream parser (ESPARSER) that is handled here. Signed-off-by:

The IR protocol can now only be set via the rc protocols sysfs file rather than via module parameters or a custom procfs file. So, it is no longer necessary to periodically check for protocol changes. The IR_RCMM protocol does not decode the Philips RC-MM protocol (12, 24 or 32 bit variants) or any protocol rc-core can encode, so this is marked RC_PROTO_UNKNOWN. Tested on Technotrend/Hauppauge WinTV Nexus-S rev2.1, which comes with a small black hauppauge remote. Signed-off-by:

Commit 020bc735 ("media: staging/imx: Allow driver to build if COMPILE_TEST is enabled") incorrectly assumed that the imx media driver had no build time dependency with IMX_IPUV3_CORE. Building on x86_64 without IMX_IPUV3_CORE causes lots of build errors such as: All these definitions come from the imx ipu3 core driver, so make sure that imx media depends on IMX_IPUV3_CORE. This reverts commit 020bc735. Reported-by:
