I would generally consider drivers dead when they have no DT support
and no platform in the upstream kernel registering the corresponding
device.
If anyone still uses this driver on SH-Mobile or R-Mobile, they
have clearly given up on upstreaming their patches by now, and
they can carry the burden of maintaining the driver out of tree,
or re-submit a working version.
