From fabbe6df130a46d5b5e7484b2273d69c4be3012a Mon Sep 17 00:00:00 2001 From: Dave Gerlach Date: Mon, 1 Jun 2015 19:22:11 -0600 Subject: [PATCH] ARM: OMAP: AM43xx hwmod: Add data for am43xx emif hwmod Without a hwmod for am43xx emif use counting for emif clockdomain does not happen correctly so it may be shut off by pm code unintentionally.
