This will fail the initcall and print a warning when the kernel runs on any
other SoC. Would it be possible to just make this a platform_driver?

If not, I think you should silently return success when the device
node is absent.

Thank you for your report.
Can' make it platform drv., as te SoC info need to be accessible by divers early.
I'll fix it to return success.
