We currently have the following devnode types: enum vfl_devnode_type { VFL_TYPE_GRABBER = 0, VFL_TYPE_VBI, VFL_TYPE_RADIO, VFL_TYPE_SUBDEV, VFL_TYPE_SDR, VFL_TYPE_TOUCH, VFL_TYPE_MAX /* Shall be the last one */ }; They all make sense, except for the first: GRABBER really refers to /dev/videoX devices, which can be capture, output or m2m, so 'grabber' doesn't even refer to their function anymore. Let's call a spade a spade and rename this to VFL_TYPE_VIDEO. Signed-off-by:Hans Verkuil <hverkuil-cisco@xs4all.nl> Acked-by:

Make sure to use the current alternate setting when verifying the interface descriptors to avoid submitting an URB to an invalid endpoint. Failing to do so could cause the driver to misbehave or trigger a WARN() in usb_submit_urb() that kernels with panic_on_warn set would choke on.

commit 1b976fc6 ("media: b2c2-flexcop-usb: add sanity checking") added an endpoint sanity check to address a NULL-pointer dereference on probe. Unfortunately the check was done on the current altsetting which was later changed. Fix this by moving the sanity check to after the altsetting is changed.

The hardware does not support capturing the field types V4L2_FIELD_SEQ_TB and V4L2_FIELD_SEQ_BT. To capture in these formats the driver needs to adjust the offset of the capture buffer and capture twice to each vb2 buffer. Signed-off-by:

To support SEQ_TB/BT not all buffers given to the hardware will be equal, the driver needs to keep track of different buffer types. Move the tracking of buffers given to hardware into a struct so additional tracking fields can be associated with each buffer. [hverkuil: fix small checkpatch warning] Signed-off-by:

An attempt to get a BUTTON control returns EACCES, not EINVAL. BUTTON controls have V4L2_CTRL_FLAG_WRITE_ONLY set, and the documentation for that flag correctly says that getting a write-only control returns EACCES. It's the description of the BUTTON type that's wrong, so fix that so they are consistent. Signed-off-by:

The driver was issuing synchronous uninterruptible control requests without using a timeout. This could lead to the driver hanging on various user requests due to a malfunctioning (or malicious) device until the device is physically disconnected. The USB upper limit of five seconds per request should be more than enough.

This exposes the white balance configuration of the ISC as v4l2 controls into userspace. There are 8 controls available: 4 gain controls, sliders, for each of the BAYER components: R, B, GR, GB. These gains are multipliers for each component, in format unsigned 0:4:9 with a default value of 512 (1.0 multiplier). 4 offset controls, sliders, for each of the BAYER components: R, B, GR, GB. These offsets are added/substracted from each component, in format signed 1:12:0 with a default value of 0 (+/- 0) To expose this to userspace, added 8 custom controls, in an auto cluster. To summarize the functionality: The auto cluster switch is the auto white balance control, and it works like this: AWB == 1: autowhitebalance is on, the do_white_balance button is inactive, the gains/offsets are inactive, but volatile and readable. Thus, the results of the whitebalance algorithm are available to userspace to read at any time. AWB == 0: autowhitebalance is off, cluster is in manual mode, user can configure the gain/offsets directly. More than that, if the do_white_balance button is pressed, the driver will perform one-time-adjustment, (preferably with color checker card) and the userspace can read again the new values. With this feature, the userspace can save the coefficients and reinstall them for example after reboot or reprobing the driver.

The aspeed video IP has some differences between SoC families. Currently the driver decides which registers to use at compile time, which means a single kernel can not be used between platforms.

These are bits so to test if a pad is a sink you use & but not ==. It looks like the only reason this hasn't caused problems before is that media_get_pad_index() is currently only used with pads that do not set the MEDIA_PAD_FL_MUST_CONNECT flag. So a pad really had only the SINK or SOURCE flag set and nothing else. Signed-off-by:

The topology that v4l2_m2m_register_media_controller() creates for a processing block actually created a source-to-source link and a sink-to-sink link instead of two source-to-sink links. Unfortunately v4l2-compliance never checked for such bad links, so this went unreported for quite some time. Signed-off-by:

Only ARGB32-type pixelformat were assumed to have 4 components, which is wrong since RGB32-type pixelformats may have an alpha channel, so they should also assume 4 color components. The XRGB32-type pixelformats really have only 3 color components, but this complicated matters since that creates strides that are sometimes width * 3 and sometimes width * 4, and in fact this can result in buffer overflows. Keep things simple by just always processing all 4 color components. In the future we might want to optimize this again for the XRGB32-type pixelformats, but for now keep it simple and robust.
