Is this a known issue with CAMSS or is something missing in the sc8280xp integration?
A known issue on my end, I also want to root cause intermittent sensor startup failure, before switching on the sensor upstream for more common use.
I'm using the following (squashed) devicetree patch from Bryan to enable the camera (everything else is upstream): https://github.com/jhovold/linux/commit/85b41b8d0efd418509df548592f95b43b9663409 The issue was there with 6.9 as well so it's not a (recent) regression. Probing the camera sometimes, but infrequently, also fails with: qcom-camss ac5a000.camss: Failed to power up pipeline: -13
Yes this. If you recall on the pm8010 I had mentioned to you about a wait-time to startup the regulator - thinking it was the regulator causing this error.
More likely the GPIO reset polarity or delay needs to be tweaked in the sensor driver.
and I'm seeing the following warning on every boot: i2c-qcom-cci ac4c000.cci: Found 19200000 cci clk rate while 37500000 was expected
That's hanging around for quite a long time 19.2 MHz is a perfectly valid clock, useless error message.
