The JH7110 clocks, the JH8100 system and always-on all follow the Xcrg pattern:
syscrg
aoncrg
stgcrg
ispcrg
voutcrg
etc.

Is there a reason the north-west, north-east and south-west breaks this pattern?
I'd have expected them to be called something like
nwcrg, JH8100_NWCLK_*, JH8100_NWRST_*,
necrg, JH8100_NECLK_*, JH8100_NERST_* and
swcrg, JH8100_SWCLK_*, JH8100_SWRST_*

Just like all the other Starfive drivers.

Yes, all these 3 JHXX00 drivers are almost identical. There should be no reason
to name any one of them differently. Having them all be as similar as possible
will make it a lot easier to maintain in the future. If you don't like a
pattern then please change it for all the similar drivers and don't make just
one of them be different.
