rtc: ds1337: Remove various legacy code and update dependencies 2026-04-03T18:06:24+00:00 Tom Rini trini@konsulko.com 2026-03-20T20:53:32+00:00 8c1ffb09d5bda6e94b71fac60aad7f1b1ba4d16a At this point there are no users of this driver which do not enable DM_RTC, so remove the legacy code and express the depdendency in Kconfig. We can further remove code related to RTC chips / options that are neither available in Kconfig nor set by any platforms. Signed-off-by: Tom Rini <trini@konsulko.com>

It was a function of Kconfig configuration that implied otherwise. Remove the unused legacy symbols. Signed-off-by: Tom Rini <trini@konsulko.com>
