This clock is present on cheaper Northstar devices like BCM53573 or
BCM47189 using Corex-A7. This driver uses PMU (Power Management Unit)
to calculate clock rate and allows using it in a generic (clk_*) way.
I thought Northstar uses Cortex A9 instead of A7?

Yeah ARMv7 instruction set but the core is Cortex A7. Both Cortex A7 and A9
use ARMv7 instructions.
OK, sorry for irrelevant part then :)
This is from BCM4709C0:
bcma: bus0: Core 10 found: ARM Cortex A9 core (ihost) (manuf 0x4BF, id
0x510, rev 0x07, class 0x0)
This is from BCM47189B0::
bcma: bus0: Core 3 found: ARM CA7 (manuf 0x4BF, id 0x847, rev 0x00, class 0x0)
This is indeed a Cortex A7-based chip, not clear if putting this chip in
the Northstar family is accurate here because it really seems to have a
different architecture from the NS/NSP family here...
Okay I got it. Good to know! I got confused by it being called
"Northstar" because as far I can remember, none of the Northstar chips
uses Cortex A7 (or maybe even that assumption is incorrect, :))
Thanks,
Ray
