Public bug reported:
OV08X40 was added as a fork from v6.9 because some of its
settings/features are either not available in the upstream kernel
driver, or conflicting with general uses in other embedded systems. This
forked driver than receive updates many times and finally in bug 2134604
we should be able to use the in-tree driver with the latest usbio-
drivers updates.
Note, when using the usbio-drivers >= WW44.4_25_ptl_pv, which maps to
Ubuntu version 0~git202510282139.ee221eca-0ubuntu1, the in-tree ov08x40
should be used. And when the in-tree ov08x40 is in use, the usbio-
drivers version must also be >= WW44.4_25_ptl_pv. That's because the
previous hacks for bug 2084059, 2/4 lanes support at 1500 Mbps,
conflicts with the latest usbio-drivers, leaving following error
messages in dmesg:
ov08x40 i2c-OVTI08F4:00: Failed regs transferred: -22
ov08x40 i2c-OVTI08F4:00: ov08x40_start_streaming failed to set regs
ov08x40 i2c-OVTI08F4:00: Failed regs transferred: -22
ov08x40 i2c-OVTI08F4:00: ov08x40_start_streaming failed to set regs
This is a follow-up for bug 2134604.
