[IMX8MP] ISP-IMX OV2775 example

@joanxie

isp-vvcam has ov2775 driver example.

But ov2775 is removed in the official release of isp-imx.

Could you provide ov2775 example for isp-imx?

I have the calibration tool which includes ov2775 xml file for isp-imx.

I am porting the sensor which uses NATIVE HDR like ov2775.

I found old isp sdk has this driver, the version is isp-imx-4.2.2.11.0, you can build this version and find driver there, I'm afraid that I couldn't share this on the public community

@joanxie

isp-imx 4.2.2.11.0 data structure and xml is out dated and it cannot be used with newer isp-vvcam.

and it does not match with the ISP porting guide documents.

I already tried mixing isp-imx 4.2.11.0 with isp-vvcam > 4.2.2.20 .

If you cannot share the newer isp-imx ov2775 in public, please email me in private.

Or tell me if our company needs to sign any document to get it. We already got the calibration tools.

Thanks

I don't have this driver for latest bsp version since our latest bsp didn't include this anymore, you can use old one, this shouldn't be big difference, maybe some function or parameters you need modified based on latest bsp

@joanxie

I have gone trough the source codes from isp-imx 4.2.2.6.0 to 4.22.24.0.

I am following IMX8MP ISP porting guideline. But there are some ISP stack functions required

clarification for user's custom sensor.

Please see my question on
