+From 7efa7cc5b807cb840c62b5bf54bf47181c9b95a6 Mon Sep 17 00:00:00 2001

+Subject: [PATCH v2] ARM: OMAP: board-ldp: add regulator info to get the microSD slot working again
+
+The ldp board was left behind when other boards got updated. The ldp info was copied from the beagleboard board file and s/beagle/ldp/g
+
+Changes since v1:
+ * dropped vsim portion since only 4 pins are hooked up
