Add the rt linux 4.1.3-rt3 as base
Import the rt linux 4.1.3-rt3 as OPNFV kvm base. It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and the base is: commit 0917f823c59692d751951bf5ea699a2d1e2f26a2 Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Date: Sat Jul 25 12:13:34 2015 +0200 Prepare v4.1.3-rt3 Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> We lose all the git history this way and it's not good. We should apply another opnfv project repo in future. Change-Id: I87543d81c9df70d99c5001fbdf646b202c19f423 Signed-off-by: Yunhong Jiang <yunhong.jiang@intel.com>

+mmc-card / eMMC bindings
+------------------------
+
+This documents describes the devicetree bindings for a mmc-host controller
+child node describing a mmc-card / an eMMC, see "Use of Function subnodes"
+in mmc.txt
+
+Required properties:
+-compatible : Must be "mmc-card"
+-reg : Must be <0>
+
+Optional properties:
+-broken-hpi : Use this to indicate that the mmc-card has a broken hpi
+ implementation, and that hpi should not be used
+
+Example:
+
+&mmc2 {
+ pinctrl-names = "default";
+ pinctrl-0 = <&mmc2_pins_a>;
+ vmmc-supply = <&reg_vcc3v3>;
+ bus-width = <8>;
+ non-removable;
+ status = "okay";
+
+ mmccard: mmccard@0 {
+ reg = <0>;
+ compatible = "mmc-card";
+ broken-hpi;
+ };
+};
