From 4e8b7544b796c4a8d4513b4070716ce42bfba840 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Mon, 24 Oct 2011 06:44:15 +0000 Subject: rtc: Make mc13783-rtc driver generic Rename mc13783-rtc so that it can be used for both MC13783 and MC13892 PMICs. efikamx board, for example, does use a MC13892 PMIC, but the RTC selection is currently made as: #define CONFIG_RTC_MC13783 ,which is not very obvious. Let the MC13783 and MC13892 RTC be selected by: #define CONFIG_RTC_MC13XXX Signed-off-by: Fabio Estevam Acked-by: Stefano Babic --- drivers/rtc/Makefile | 2 +- drivers/rtc/mc13783-rtc.c | 79 ----------------------------------------------- drivers/rtc/mc13xxx-rtc.c | 79 +++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 80 insertions(+), 80 deletions(-) delete mode 100644 drivers/rtc/mc13783-rtc.c create mode 100644 drivers/rtc/mc13xxx-rtc.c (limited to 'drivers/rtc') diff --git a/drivers/rtc/Makefile b/drivers/rtc/Makefile index df440c62ff..a16f59051d 100644 --- a/drivers/rtc/Makefile +++ b/drivers/rtc/Makefile @@ -50,7 +50,7 @@ COBJS-$(CONFIG_RTC_M41T62) += m41t62.o COBJS-$(CONFIG_RTC_M41T94) += m41t94.o COBJS-$(CONFIG_RTC_M48T35A) += m48t35ax.o COBJS-$(CONFIG_RTC_MAX6900) += max6900.o -COBJS-$(CONFIG_RTC_MC13783) += mc13783-rtc.o +COBJS-$(CONFIG_RTC_MC13XXX) += mc13xxx-rtc.o COBJS-$(CONFIG_RTC_MC146818) += mc146818.o COBJS-$(CONFIG_MCFRTC) += mcfrtc.o COBJS-$(CONFIG_RTC_MK48T59) += mk48t59.o diff --git a/drivers/rtc/mc13783-rtc.c b/drivers/rtc/mc13783-rtc.c deleted file mode 100644 index 70ea8a1589..0000000000 --- a/drivers/rtc/mc13783-rtc.c +++ /dev/null @@ -1,79 +0,0 @@ -/* - * Copyright (C) 2008, Guennadi Liakhovetski - * - * See file CREDITS for list of people who contributed to this - * project. - * - * This program is free software; you can redistribute it and/or - * modify it under the terms of the GNU General Public License as - * published by the Free Software Foundation; either version 2 of - * the License, or (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
