From 4321dc8dff356cdc852936fcfb443463b504890d Mon Sep 17 00:00:00 2001 From: Keerthy Date: Fri, 19 Feb 2016 10:08:55 +0530 Subject: [PATCH] ARM: AM43XX: hwmod: Add rtc hwmod The patch registers the rtc hwmod on AM437x chips. The RTC module is physically present on the AM438x SoC used on AM43X-EPOS-EVM, but it is permanently disabled. A secure RTC is used instead on these devices, where needed. Hence adding it selectively using a separate list to get RTC Module functional on the other am43x SoCs used on am437x-gp-evm and am437x-sk-evm.
