Given that much of the driver code is the same than in the IPU6 driver (in particular split into devices, DMA, MMU and V4L2 / MC API related code), we should share at least that instead of looking to maintain two copies of it separately. The IPU7 driver probably has had a different starting point for development than the current IPU6 driver so there are a fair amount of differences in that code now but it is largely not due to differences in the hardware itself, for instance, the lack of metadata or multiple virtual channel support you listed below. > > > TODO list: > 1.

From: Bingbu Cao <bingbu.cao@intel.com> This patch series adds a driver for Intel IPU7 input system. IPU7 is the seventh generation of Imaging Processing Unit, it is a PCI device which can be found in some Intel Client Platforms such as Intel Lunar Lake and Panther Lake, etc. User can use IPU7 to capture images from MIPI camera sensors, support both MIPI CSI DPHY and CPHY. IPU7 input system driver uses MC and V4L2 sub-device APIs besides V4L2. - ipu7.c: the IPU7 PCI device driver probe, basic hardware configuration and initialization - ipu7-bus: Initialise and register the auxiliary device for IS - ipu7-buttress: Hardware buttress interfaces to allow driver to program to enable the power, firmware authentication and interrupt handling. - ipu7-mmu and ipu7-dma: IPU MMU table setup and IPU DMA mapping APIs - ipu7-cpd and ipu7-boot: firmware format parse and firmware boot flow - abi: a series of ABI headers used by driver and firmware - ipu7-syscom: syscom communication interfaces used by driver to queue commands to firmware - ipu7-isys: main IPU7 input system driver, it registers CSI2 as v4l2 sub-devices and the capture as video devices. TODO list: 1. ABI headers cleanup (currently a copy from firmware as it is still in development and updating regularly, need cleanup to unifiy the headers) 2. add metadata capture support 3. add multiple virtual-channels capture support 4. remove unsecure mode code as secure mode is force to enabled in product Bingbu Cao (7): media: Rename the IPU PCI device table header and add IPU7 PCI IDs media:
