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.
