I never tried the PCIe driver with something else than an NVMe, and I don't have the HW to, so I can't help...
Did you try this patch ?
https://git.kernel.org/pub/scm/linux/kernel/git/lpieralisi/pci.git/commit/?h=pci/dwc&id=87dccf09323fc363bd0d072fcc12b96622ab8c69
But I'm curious, what did you use to connect a DVB card on the M.2 port ?

You should find where this failed.
You can find by calling :
$ scripts/faddr2line vmlinux si2183_init+0x34
where you built the kernel.

The PCIe arch is different between Intel and ARM boards, especially the Amlogic ones
since we are limited to 32bit physical adressing, so it's expected PCIe card for PCs could
fail on such platforms.

Nice to hear, thx for the reference.

It's known GFX cards doesn't work well on ARM64 with limited physical physical PCI space like here.

Ok, so maybe these dvb driver are broken somehow.

Looks like the i2c device is not found, so maybe a driver is missing somewhere to have i2c over
PCI. Since it's out of tree, can't really help here.
You should compare with another ARM board where is works.
