From 59e8ce574445c5e7a65ec36f47a54803de704e96 Mon Sep 17 00:00:00 2001 From: Byron Bradley Date: Sun, 10 Feb 2008 22:31:09 +0100 Subject: [PATCH] [ARM] 4826/1: Orion: Register the RTC interrupt on the TS-209 The QNAP TS-209 has its RTC interrupt on GPIO 3. Setup this as an interrupt and pass it to the i2c_board_info.
