Subject: rtc: Update Kconfig dependencies
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=99bc9d07b7304f9db08abd6c86229043441ea0b8;p=thirdparty%2Fu-boot.git

rtc: Update Kconfig dependencies

Update the dependencies for RTC drivers which did not express a
requirement on DM_RTC, or in some cases on DM_RTC being disabled. In a
few cases, when DM_RTC is disabled we also require DM_I2C to also be
disabled or for POWER_LEGACY to be enabled.
