Is there a name for 0x674?
No in any sources published by Broadcom. I was experimenting with bit
0x10000 in PMU_SLOW_CLK_PERIOD and 0x10000 in 0x674. Both have to be
set. I was suspecting that maybe one of them is just some trigger and
it can be switched back to 0, but it's not the case. I definitely need
to set both of them to get clock working.
Ok no worries, raw number is fine.
