From 8daaed76383aaae1d094d3d65d34890b2c6da24b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 14 Sep 2023 17:55:22 +0200 Subject: sh: Remove superhyway bus support The superhyway bus driver was only referenced on SH4-202, which is now gone, so remove it all as well. I could find no trace of anything ever calling superhyway_register_driver(), not in the git history but also not on the web, so I assume this has never served any purpose on mainline kernels.
