* media: ti: Add CSI2RX support for J721EJai Luthra2023-10-124-0/+1174
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | ccs_pm_get_init() depends on the return values > 0 of pm_runtime_get_sync(), thus it can't use pm_runtime_resume_and_get(). There's even a comment in the driver on this, a few lines above the code.

* media: ccs: Use sub-device active stateSakari Ailus2023-10-072-186/+104
| | | | | | | | | | | | 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. This still removes a lot of code as the code paths for active and try state are the same in many cases.

* media: ccs: Obtain media bus formats before initialising up sub-devicesSakari Ailus2023-10-071-6/+6
| | | | | | | | | | | The available mbus codes will soon be needed earlier, at the time sub-devices are initialisaed. This is due to calling init_cfg() op via the v4l2_subdev_init_finalize(). Move ccs_get_mbus_formats() before ccs_init_subdev() calls. Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>
