Subject: [PATCH] rtc: Remove legacy DS1338 support
Date: Fri, 20 Mar 2026 14:53:31 -0600 [thread overview]
Message-ID: <20260320205331.3788710-1-trini@konsulko.com> (raw)
The DS1338 RTC chip is supported in DM mode by the DS1307 driver, and at
this point all users have been using this functionality. It was a
function of Kconfig configuration that implied otherwise. Remove the
unused legacy symbols.
