From 1c02cbfec5c7754cb16456fcb26592a20781cdff Mon Sep 17 00:00:00 2001 From: Nicolae Rosia Date: Wed, 23 Nov 2016 10:55:57 +0200 Subject: [PATCH] rtc: twl: make driver DT only Since there are no platform based users and all users of this code are TI OMAP-based which is DT only, it makes sense to remove unused code.
