From 3cfb411a64b7517bd2039e4d79da27b97179bece Mon Sep 17 00:00:00 2001 From: Christopher Spinrath Date: Mon, 13 Jun 2016 01:24:56 +0200 Subject: ARM: dts: utilite-pro: add mmc card slot support The Utilite Pro has a mmc card slot connected to the usdhc3 controller. There is no card detection until hardware revision 1.3. Add support for it and signal the controller with the broken-cd property that polling has to be used to detect a card.
