From: Kevin Hilman <khil...@ti.com>
commit 6b8029fab64164b5895d58d23229b75c82e3a6fc (rtc: kconfig: remove
unnecessary dependencies) removed various 'depends on RTC_CLASS'
dependencies but also removed a few 'default RTC_CLASS' statements,
which actually changed default behavior.
This resulted in the various RTC interfaces (sysfs, proc, dev) all
being disabled by default, even when RTC_CLASS is enabled:
# CONFIG_RTC_INTF_SYSFS is not set
# CONFIG_RTC_INTF_PROC is not set
# CONFIG_RTC_INTF_DEV is not set
which is different from previous behavior (all of these where enabled.)
To fix, add back the 'default RTC_CLASS' statments to each of the
RTC_INTF_* options.
I noticed this because some RTC tests started failing on my TI OMAP
platforms because /dev/rtc0 was not present anymore, even though the
driver was present and RTC_CLASS was enabled.
