Hi,
We have custom board with AM4378 as the MPU. We are using the NXP HDMI transmitter but we are getting the following errors during startup:
[ 25.873656] tda998x 1-0070: found TDA19988

[ 26.080138] omapdrm: probe of omapdrm.0 failed with error -22
We are using the "ti-linux-kernel" repository on the "ti-linux-5.10.y" branch to build our kernel image. The full logs and related device tree parts are attached as well as the config file obtained by "cat /proc/config.gz".
Any ideas how we can resolve this? Your help is appreciated.
Regards,
Berkay
