ipu6: ov01a1s: failed to init camera

[You-Sheng Yang]

With proposed oem-5.14 kernel from bug 1955383 and latest middleware installed, cheese no longer gives video streaming.

Installed middleware are:
* linux-firmware: 1.187.24+staging.39
* libipu6: 0~git202112020845.a14b40c-1~ubuntu20.04.1
* libcamhal-common: 0~git202112130639.4585612~ubuntu20.04.1
* libcamhal0: 0~git202112130639.4585612~ubuntu20.04.1
* libgsticamerainterface-1.0-1: 0~git202112230614.eb13eb1~ubuntu20.04.1
* gstreamer1.0-icamera: 0~git202112230614.eb13eb1~ubuntu20.04.1

But when switched back to following ones, same oem-5.14 kernel works just fine:

* libipu6: 0~git202104021802.45905c6-1~ubuntu20.04.1
* libcamhal-common: 0~git202105200731.43dcb4c~ubuntu20.04.1
* libcamhal0: 0~git202105200731.43dcb4c~ubuntu20.04.1
* libgsticamerainterface-1.0-1: 0~git202104021904.aeed9b9~ubuntu20.04.1
* gstreamer1.0-icamera: 0~git202104021904.aeed9b9~ubuntu20.04.1

Attach kernel dmesg captured with 202104 middleware installed. Basically there doesn't seem to be anything different from the dmesg captured with latest middleware.

[You-Sheng Yang (vicamo)]

kernel fails to initialize INT3472 from power_logic_ctrl driver dedicated for IPU6 camera:

[ 6.032879] intel_ulpss 3-6:1.0: found: 3-6:1.0 -> INTC1074
[ 6.033122] intel_ulpss 3-6:1.0: Found: 3-6:1.0 -> INTC1075
[ 6.119468] int3472-discrete INT3472:06: error -EBUSY: Failed to map GPIO to clock
[ 6.119583] int3472-discrete: probe of INT3472:06 failed with error -1

But this appears in both cases so it's not the root cause.

This change was made by a bot.

From the media-ctl output, it suggests the source/sink pads formats
might not be initialized correctly.

[You-Sheng Yang (vicamo)]

This is most likely a bug in libcamhal-common, not the kernel.
