 - lore: 20221118075152.19537-1-wsa+renesas@sang-engineering.com # [RFC PATCH v2] clocksource/drivers/sh_cmt: access registers according to spec

comments:
 - we get timeout errors when using the 'clocksource-switch' test from the Kernel selftests
 - only Gen4 is affected
 - intensive testing showed that Gen3 is affected, too. Just rarely, a lot less than Gen4
 - RFC v1 sent
 - RFC v2 sent
