Hi Prabhakar,
I'm currently testing the OV5640 CCIR656 embedded synchronisation mode
on STM32MP1 running STM32 DCMI camera interface.
Tests not yet fully completed but sounds good, more details below.

As discussed separately I would prefer to better understand issue before
going to this patch.
Nevertheless I have some remarks in code in case we'll need it at the end.

Thanks for your patches, good to see one more OV5640 stakeholder
upstreaming some fixes/features.
I'm also using a parallel setup with OV5640 connected on STM32 DCMI
camera interface.
First basic tests have not shown any regressions on my side but I would

Add support of several sub-devices within pipeline instead
of a single one.
This allows to support a CSI-2 camera sensor connected

Hi Andi,
So do both, memset then strscpy:
+ memset(msg.name, 0, sizeof(msg.name));
+ if (strscpy(msg.name, name, sizeof(msg.name)) <= 0)
+ goto err;
BR,
Hugues.

Hi Andi,
We have already discussed about that here:
https://lore.kernel.org/patchwork/patch/866406/
Now that strscpy is largely deployed within kernel, could you retest
with the change I suggested ?
Best regards,
Hugues.

Start streaming was sometimes failing because of pm_runtime_get_sync()
non-0 return value. In fact return value was not an error but a
positive value (1), indicating that PM was already enabled.
Fix this by going to error path only with negative return value.

Do not wait for interrupt completion when stopping streaming,
stopping sensor and disabling interruptions are enough.
