Hi Luca,

Quick question regarding IMX274 driver that was up streamed by you.

Upstream IMX274 driver programs Y_OUT_SIZE correctly based on IMX274=20
datasheet and register mode table for Y_OUT_SIZE where it includes 6=20
ignored area of effective pixels + 8 effective margin for color=20
processing pixels.

So, Y_OUT_SIZE register value =3D height + 14

But somehow with this we are not seeing full frame on CSI.

In our internal NVIDIA IMX274 driver, we are programming Y_OUT_SIZE to=20
exact height=C2=A0 Y_OUT_SIZE =3D height

So for debug, followed the same and updated upstream IMX274 driver to=20
program Y_OUT_SIZE =3D crop.height locally and I see all resolutions=20
working fine with this.

Checking with Sony on whats causing sensor not to send full frame when=20
Y_OUT_SIZE is set to height + 14.

But thought to check with you in parallel if there are any known issues=20
related to this with IMX274 driver.

Appreciate your response.

Thanks & Regards,

Sowjanya
