HDMI display related issues

[Xwd]

I am using STM32MP157C with kernel version 6.6, and the problem I am currently experiencing is that HDMI cannot display. The hardware design uses SII9022ACNU chip, and the driver keeps reporting probe failure with a return value of -11. The SII9022 HDMI chip does not respond to I2C communication on the 6.6 kernel, and manually resetting GPIO is also ineffective. Have you encountered similar problems and how have they been resolved。

can you share the log information in more detail which include -11 value?

BTW, does the system work at prototype phase or mass production phase?
