TI's J721E uses the Cadence CSI2RX and DPHY peripherals to facilitate capture over a CSI-2 bus. The Cadence CSI2RX IP acts as a bridge between the TI specific parts and the CSI-2 protocol parts. TI then has a wrapper on top of this bridge called the SHIM layer. It takes in data from stream 0, repacks it, and sends it to memory over PSI-L DMA. This driver acts as the "front end" to V4L2 client applications. It implements the required ioctls and buffer operations, passes the necessary calls on to the bridge, programs the SHIM layer, and performs DMA via the dmaengine API to finally return the data to a buffer supplied by the application.

The devnode can be used by media-ctl and other userspace tools to perform configurations on the subdev. Without it, media-ctl returns ENOENT when setting format on the sensor subdev. Signed-off-by:

Firstly, there is no VC_EN bit present in the STREAM_DATA_CFG register. Bit 31 is part of the VL_SELECT field. Remove it completely. Secondly, it makes little sense to enable ith virtual channel for ith stream. Sure, there might be a use-case that demands it. But there might also be a use case that demands all streams to use the 0th virtual channel. Prefer this case over the former because it is less arbitrary and also makes it very clear what the limitations of the current driver is instead of giving a false impression that multiple virtual channels are supported.

The stream stop procedure says that the STOP bit should be set when the stream is to be stopped, and then the ready bit in stream status register polled to make sure the STOP operation is finished. Signed-off-by:

This resets the stream state machines and FIFOs, giving them a clean slate. On J721E if the streams are not reset before starting the capture, the captured frame gets wrapped around vertically on every run after the first. Signed-off-by:

Some platforms like TI's J721E can have the CSI2RX paired with an external DPHY. Use the generic PHY framework to configure the DPHY with the correct link frequency. Signed-off-by:

The format is needed to calculate the link speed for the external DPHY configuration. It is not right to query the format from the source subdev. Add get_fmt and set_fmt pad operations so that the format can be configured and correct bpp be selected. Initialize and use the v4l2 subdev active state to keep track of the active formats. Also propagate the new format from the sink pad to all the source pads. Signed-off-by:

The notifier is added to the global notifier list when registered. When the module is removed, the struct csi2rx_priv in which the notifier is embedded, is destroyed. As a result the notifier list has a reference to a notifier that no longer exists. This causes invalid memory accesses when the list is iterated over. Similar for when the probe fails. Unregister and clean up the notifier to avoid this. Fixes: 1fc3b37f ("media: v4l: cadence: Add Cadence MIPI-CSI2 RX driver") Signed-off-by:

The data-lanes property maps the logical lane numbers to the physical lane numbers. The position of an entry is the logical lane number and its value is the physical lane number. Since one physical lane can only map to one logical lane, no number in the list should repeat. Add the uniqueItems constraint on the property to enforce this. Signed-off-by:

imon driver probes two USB interfaces, and at the probe of the second interface, the driver assumes blindly that the first interface got bound with the same imon driver. It's usually true, but it's still possible that the first interface is bound with another driver via a malformed descriptor. Then it may lead to a memory corruption, as spotted by syzkaller; imon driver accesses the data from drvdata as struct imon_context object although it's a completely different one that was assigned by another driver. This patch adds a sanity check -- whether the first interface is really bound with the imon driver or not -- for avoiding the problem above at the probe time.

When building the modules 'modpost' warns about missing MODULE_DESCRIPTION. Since almost none of the rc keymap modules have this, it produces a lot of warnings. As a first step to fixing all media modules, add this line to all keymaps. The description should be a human-readable string describing the remote or the remote controller that the keymap can be used with. Note that keymaps/rc-cec.c is actually compiled into the rc-core, so that is the sole keymap source that didn't need this. Signed-off-by:

Make use of sub-device active state. In most cases the effect on need for acquiring the mutex is non-existent as access to the driver's core data structure still needs to be serialised.
