Re: [14-CURRENT]BBB can't boot 14-CURRENT GENERICSD-20210805

I applied ti_sysc.c patch with 14.0-CURRENT-arm-armv7-GENERICSD-20210805.

Unfortunately, I got another panic(No usable event timer found!)

I compared between13-stable and 14-current.
14-current kernel can't attach clock management.
ti_prcm0: <TI Power and Clock Management> mem 0-0x1fff on ti_sysc0

If I replace dtb directory(I got from 13-stable dtb directory and I put FAT
partition dtb and /boot/dtb), 14-GENERICSD can't boot....
