Bug description:
[SRU Justification]
BugLink: https://bugs.launchpad.net/bugs/2060101
[Impact]
ov08x40 camera sensor is not working on IPU6 platforms.
[Fix]
A few changes from upstream kernel as well as a not yet upstreamed patch in
the Intel ipu6-drivers GitHub repo.
* commit b1a42fde ("media: ov08x40: Avoid sensor probing in D0 state")
* commit eea8f730 ("media: ov08x40: Modify the tline calculation in different
modes")
*
https://github.com/intel/ipu6-drivers/blob/Release_20240624/patch/v6.8/0001-media-ov08x40-Add-Tline-calculation-and-handshake-pi.patch
[Test Case]
The proposed kernel should have been built along with the updated
ipu6-drivers dkms. To verify ipu6-drivers alone, one will need
experimental kernels from https://launchpad.net/~canonical-hwe-
team/+archive/ubuntu/intermediate-kernel.
Here are steps for verifying kernels from -proposed pocket:
1. test camera after rebooting into a proposed kernel,
2. run suspend/resume stress test plan.
3. verify camera still working
[Where problems could occur]
These fixes are quite limited to ipu6/ivsc platforms, and affected no
power-consumption or other noticible problem.
[Other Info]
The fixing commits/patches were meant for in-tree driver, but yet it
changes device power up sequence and may affect platforms not
interested in IPU6 enablement. It is then duplicated into ipu6-drivers
dkms to avoid any unexpected side effect.
While some of the fixes are still under upstream review, meaning
they're not yet available in any kernel release, linux-
unstable/oracular/noble and oem-6.8/6.1x will be nominated for a
rebuild against new dkms.
