Since the removal of legacy (non-multiplatform) support this driver has not
been used by any Renesas ARM based SoCs.

This is part of an ongoing process to migrate from ARCH_SHMOBILE to
ARCH_RENESAS the motivation for which being that RENESAS seems to be a more
appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.

I think dropping the SUPERH dependency is the right approach here, as all
SuperH platforms using the driver select ARCH_SHMOBILE.

"sh_keysc" is used on SH_MIGOR, SH_ECOVEC, SH_KFR2R09, SH_7722_SOLUTION_ENGINE,
and SH_7724_SOLUTION_ENGINE, which depend on either CPU_SUBTYPE_SH7722 or
CPU_SUBTYPE_SH7724, and both select ARCH_SHMOBILE.

FWIW, this has never been enabled on sh7343. But CPU_SUBTYPE_SH7343 also
selects ARCH_SHMOBILE, so we're safe.

I think you forgot a proper prefix in the subject...

Thanks, I agree!

You are right that the SH architecture is the main consumer at this
point. I do however vaguely recall ARM shmobile G3EVM and G4EVM
including sh7367 and some other SoC also having a KEYSC hardware block
included. Due to the iffy interrupt controller upstream support for
those boards/socs were killed off quite some time ago while (not)
migrating to DT. So I think this KEYSC driver is simply a left over
from that time.

Cheers,

Note that sh73a0 also has keysc, but I don't think it's usable on kzm9g
(after a quick look at the schematics).

Indeed, sorry about that.
