How can I set 56 pin of M.2 connector to High?

[Shinya]

Hi NXP Tech Team,

I'm using i.MX 8QuadMax MEK with L5.4.70 kernel image.

Could you tell me the way to set 56 pin of M.2 connector to High?
I think it's need to set LVDS1_I2C0_SDA of MIMX8QM6AVUFFAB to High(1.8V), but I don't know the way.

Regards,

Hi Aldo

Sorry for my late response.

I confirmed whethre the 56 pin is High with the image which included my changes.
So I re-confirmed it with the image which didn't incluede my changes and I could confirm that the pin is High.

Thank you for your support.

Best Regards,
Shinya
