[U-Boot] [PATCH v2] drivers: rtc: remove dead drivers
Masahiro Yamada
yamada.m at jp.panasonic.com
Mon Aug 4 01:09:46 CEST 2014
The following configs are not defined at all:
- CONFIG_RTC_DS1388
- CONFIG_RTC_ISL1208
- CONFIG_RTC_MX27
- CONFIG_RTC_PL031
- CONFIG_RTC_RS5C372A
- CONFIG_SYS_DS1388_TCR_VAL
Signed-off-by: Masahiro Yamada <yamada.m at jp.panasonic.com>
---
I built all the boards and I confirmed this patch is harmless.
Changes in v2:
- Fix drivers/rtc/ds1337.c
CONFIG_SYS_RTC_DS1337 is not defined at all
