Describe the bug

I'm trying to build a kernel with compiled in drivers for 7" official touchscreen (V1) for Rpi5. But there seems to be some i2c initialization issue and the touchscreen fails to initialize. When compiling touchscreen related drivers as modules and loading them manually after boot everything works.

Steps to reproduce the behaviour

Build kernel without loadable modules and support for the 7" touchscreen: config_kern.txt
---> touchscreen does not work: dmesg_kern.txt

Build kernel with loadable modules: config_mod.txt
and loading the modules manually afterwards: lsmod_mod.txt
---> touchscreen works: dmesg_mod.txt

Device (s)

Raspberry Pi 5

System

kernel 6.12.42 (made with buildroot)
