The generic metadata pixel formats (V4L2_META_FMT_GENERIC_*) are meant to be used in conjunction with device-specific media bus codes. Those codes are work in progress and not available in the upstream kernel yet. To make sure the generic metadata pixel formats won't be used by userspace until we have the full infrastructure in place, keep their definition private to the kernel for now. Signed-off-by:

IPU6 CSI-2 D-PHY hardware varies on different platforms, current IPU6 has three D-PHY hardware instances which are used on Tigerlake, Alder lake, Meteor lake and Jasper lake. MCD D-PHY is included in Tigerlake and Alder lake, DWC D-PHY is included in Meteor lake. Each PHY has its own register interface, the input system driver calls the appropriate D-PHY callbacks for the hardware set in isys_probe(). Signed-off-by:

Syscom is an inter-process(or) communication mechanism between an IPU and host. Syscom uses message queues for message exchange between IPU and host. Each message queue has its consumer and producer, host queue messages to firmware as the producer and then firmware to dequeue the messages as consumer and vice versa. IPU and host use shared registers or memory to reside the read and write indices which are updated by consumer and producer. Signed-off-by:

The Intel IPU6 has internal microcontrollers (scalar processor, SP) which are used to execute the firmware. The SPs can access IPU internal memory and system DRAM mapped to its an internal 32-bit virtual address space. This patch adds a driver for the IPU MMU and a DMA mapping implementation using the internal MMU. The system IOMMU may be used besides the IPU MMU. Signed-off-by:

For IPU6, firmware is generated and released as signed Code Partition Directory (CPD) format file which is aligned with the SPI flash code partition definition. The CPD format includes CPD header, manifest, metadata and module data. The driver parses them according to the CPD layout to acquire each component. Signed-off-by:

The IPU6 buttress is the interface between IPU device (input system and processing system) with rest of the SoC. It contains overall IPU hardware control registers, these control registers are used as the interfaces with the Intel Converged Security Engine and Punit to do firmware authentication and power management.

Even though the IPU input system and processing system are in a single PCI device, each system has its own power sequence. Powering up the processing system depends on first powering up the input system. Besides, both the input and processing systems have their own MMU hardware for IPU DMA address mapping. Register the IS/PS devices on auxiliary bus and attach power domain to implement the power sequence dependency. Signed-off-by:

Intel Image Processing Unit 6th Gen includes input and processing systems but the hardware presents itself as a single PCI device in system. The IPU6 PCI device driver basically does PCI configurations and loads the firmware binary, initialises IPU virtual bus and sets up platform specific variants to support multiple IPU6 devices in single device driver.

Use IPU bridge to instantiate software nodes for IPU6 related devices. If the IPU6 device is probed before the MEI CSI device is created, neither will probe unless there are further devices probed successfully which triggers re-probe of both IPU6 and MEI CSI.

This is a packed grey-scale image format with a depth of 14 bits per pixel. Every four consecutive samples are packed into seven bytes. Each of the first four bytes contain the eight high order bits of the pixels, and the three following bytes contains the six least significants bits of each pixel, in the same order. As the other formats only needed 5 bytes before, append two bytes in the documentation array. Signed-off-by:

Sakari Ailus authored
The len_routes field is used to tell the size of the routes array in struct v4l2_subdev_routing. This way the number of routes returned from S_ROUTING IOCTL may be larger than the number of routes provided, in case there are more routes returned by the driver. Note that this uAPI is still disabled in the code, so this change can safely be done. Anyone who manually patched the code to enable this uAPI must update their code. The patch also increases the number of reserved fields in struct v4l2_subdev_routing. Signed-off-by:

Add two new functions, v4l2_subdev_lock_states() and v4l2_subdev_unclock_states(), to acquire and release the state of two sub-devices. They differ from calling v4l2_subdev_{un,}lock_state() so that if the two states share the same lock, the lock is acquired only once. Also use the new functions in v4l2_subdev_link_validate().
