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 diff --git a/README b/README index c05c40a..46f062f 100644 --- a/README +++ b/README @@ -876,7 +876,7 @@ The following options need to be configured: CONFIG_RTC_MPC8xx - use internal RTC of MPC8xx CONFIG_RTC_PCF8563 - use Philips PCF8563 RTC - CONFIG_RTC_MC13783 - use MC13783 RTC + CONFIG_RTC_MC13XXX - use MC13783 or MC13892 RTC CONFIG_RTC_MC146818 - use MC146818 RTC CONFIG_RTC_DS1307 - use Maxim, Inc.
