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.
