I got media-ci build errors:

Do you think is it OK using 1 table to cover IPU6 and IPU7?

Static const tables in a header isn't that great to begin with, but the
alternative would be another module which is way overkill. Two headers
would make sense in this case I think -- the tables are separate in any
case.

ivsc is another user of the IPU6 table, but I don't see that other driver
need IPU7 table so far. So I want to keep the ipu7 table private without
touching the table.h (Drop 1/8).

Intel Image Processing Unit 7th Gen includes input and processing systems
and the hardware presents itself as a single PCI device in system same
as IPU6.
The IPU7 PCI device driver basically does PCI configurations, basic
hardware configuration by its buttress interfaces, loads the
firmware binary, register the auxiliary device which serve for the ISYS
device driver.

From: Bingbu Cao <bingbu.cao@intel.com>
The Intel IPU7 has internal microprocessor which runs the firmware
The microprocessor accesses system DRAM by its internal 32-bit virtual
address space. Driver should setup the MMU table and expose the DMA
APIs for memory buffer mapping.
This patch adds the IPU MMU and a DMA mapping implementation to setup
the internal MMU hardware.

IPU7 irmware is generated and released as signed Code Partition
Directory (CPD) format file which is aligned with the SPI flash code
partition definition. The driver parses the CPD based on the layout.
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.
IPU7 firmware defined its boot sequence, driver setup the boot
configuration and program the boot parameters to start and run
the firmware.

The main input system driver mainly cover the basic hardware setup, v4l2
devices registration, firmware stream interfaces and interrupt handling.
Input system CSI2 receiver is exposed as a v4l2 sub-device. Each CSI2
sub-device represent one single CSI2 hardware port which be linked with
external sub-device such camera sensor by linked with ISYS CSI2's sink
pad. The CSI2 source pad is linked to the sink pad of video capture device.
Register V4L2 video device and setup the VB2 queues to support video
capture. Video streaming callback will trigger the input system driver to
construct a input system stream configuration for firmware based on data
type and stream ID and then queue buffers to firmware to do capture.
IPU7 CSI-2 D-PHY hardware is a Synopsys DWC MIPI CSI2 Rx IP, the driver
program the DPHY to receive MIPI data from camera sensors.

+This is a list of things that need to be done to get this driver out of the
+staging directory.
+
+- ABI headers cleanup
+ Cleanup the firmware ABI headers
+
+- Add metadata capture support
+ The IPU7 hardware should support metadata capture, but it is not
+ fully verified with IPU7 firmware ABI so far, need to add the metadata
+ capture support.
+
+- Refine CSI2 PHY code
+ Refine the ipu7-isys-csi2-phy.c, move the hardware specific variant
+ into structure, clarify and explain the PHY registers to make it more
+ readable.
+
+- Work with the common IPU module
+ Sakari commented much of the driver code is the same than the IPU6 driver.
+ IPU7 driver is expected to work with the common IPU module in future.
