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.
