Intel Computer Vision Sensing Driver Now Ready For Nova Lake

The main set of media subsystem updates have been merged for the ongoing Linux 7.3 merge window. Notable this round is the Intel Computer Vision Sensing "CVS" driver merged the previous cycle now supporting next-gen Nova Lake platforms.

The Intel Computer Vision Sensing driver was merged with the media changes in Linxu 7.2. The Intel CVS driver serves as a Video 4 Linux 2 (V4L2) sub-device for managing CSI-2 link ownership between Linux and firmware for camera sensors. The CVS is used for presence detection features like walk-away lock, wake-on-approach, and adaptive dimming. With Linux 7.2 the Intel CVS media driver was enabled for Arrow Lake, Lunar Lake, and Panther Lake platforms while in Linux 7.3 is extended for Nova Lake.

Just new PCI device ID and ACPI IDs are needed for the Intel CVS and IPU bridge code for preparing the Nova Lake support.

Also new on the media side for Linux 7.3 is adding support for the Milos VPU 2.0 to the Iris driver. That's the Qualcomm Iris decode media driver and not to be confused with the Intel Iris Gallium3D graphics driver in Mesa. Milos is the codename for Qualcomm's SM7635 / Snapdragon 7s Gen 3 SoC.

The media code in Linux 7.0 also adds Dreamchip RPPX1 ISP framework support, the VSP1 driver adding the Renesas RZ/T2H and RZ/N2H, and the V4L2 core code now allowing unknown HDR10 white point and luminance values. Lastly there is also Sony IMX678 and IMX471m, Himax HM1092 IR sensor support. More details within this pull.
