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>

+=== AB8500 Fuel Gauge Driver ===
+
+AB8500 is a mixed signal multimedia and power management
+device comprising: power and energy-management-module,
+wall-charger, usb-charger, audio codec, general purpose adc,
+tvout, clock management and sim card interface.
+
+Fuelgauge support is part of energy-management-modules, other
+components of this module are:
+main-charger, usb-combo-charger and battery-temperature-monitoring.
+
+The properties below describes the node for fuelgauge driver.
+
+Required Properties:
+- compatible = This shall be: "stericsson,ab8500-fg"
+- battery = Shall be battery specific information
+ Example:
+ ab8500_fg {
+ compatible = "stericsson,ab8500-fg";
+ battery = <&ab8500_battery>;
+ };
+
+dependent node:
+ ab8500_battery: ab8500_battery {
+ };
+ This node will provide information on 'thermistor interface' and
+ 'battery technology type' used.
+
+Properties of this node are:
+thermistor-on-batctrl:
+ A boolean value indicating thermistor interface to battery
+
+ Note:
+ 'btemp' and 'batctrl' are the pins interfaced for battery temperature
+ measurement, 'btemp' signal is used when NTC(negative temperature
+ coefficient) resister is interfaced external to battery whereas
+ 'batctrl' pin is used when NTC resister is internal to battery.
+
+ Example:
+ ab8500_battery: ab8500_battery {
+ thermistor-on-batctrl;
+ };
+ indicates: NTC resister is internal to battery, 'batctrl' is used
+ for thermal measurement.
+
+ The absence of property 'thermal-on-batctrl' indicates
+ NTC resister is external to battery and 'btemp' signal is used
+ for thermal measurement.
+
+battery-type:
+ This shall be the battery manufacturing technology type,
+ allowed types are:
+ "UNKNOWN" "NiMH" "LION" "LIPO" "LiFe" "NiCd" "LiMn"
+ Example:
+ ab8500_battery: ab8500_battery {
+ stericsson,battery-type = "LIPO";
+ }

+TI BQ24735 Charge Controller
+~~~~~~~~~~
+
+Required properties :
+ - compatible : "ti,bq24735"
+
+Optional properties :
+ - interrupts : Specify the interrupt to be used to trigger when the AC
+ adapter is either plugged in or removed.
+ - ti,ac-detect-gpios : This GPIO is optionally used to read the AC adapter
+ presence. This is a Host GPIO that is configured as an input and
+ connected to the bq24735.
+ - ti,charge-current : Used to control and set the charging current. This value
+ must be between 128mA and 8.128A with a 64mA step resolution. The POR value
+ is 0x0000h. This number is in mA (e.g. 8192), see spec for more information
+ about the ChargeCurrent (0x14h) register.
+ - ti,charge-voltage : Used to control and set the charging voltage. This value
+ must be between 1.024V and 19.2V with a 16mV step resolution. The POR value
+ is 0x0000h. This number is in mV (e.g. 19200), see spec for more information
+ about the ChargeVoltage (0x15h) register.
+ - ti,input-current : Used to control and set the charger input current. This
+ value must be between 128mA and 8.064A with a 128mA step resolution. The
+ POR value is 0x1000h. This number is in mA (e.g. 8064), see the spec for
+ more information about the InputCurrent (0x3fh) register.
+
+Example:
+
+ bq24735@9 {
+ compatible = "ti,bq24735";
+ reg = <0x9>;
+ ti,ac-detect-gpios = <&gpio 72 0x1>;
+ }

+TPS65090 Frontend PMU with Switchmode Charger
+
+Required Properties:
+-compatible: "ti,tps65090-charger"
+
+Optional Properties:
+-ti,enable-low-current-chrg: Enables charging when a low current is detected
+ while the default logic is to stop charging.
+
+This node is a subnode of the tps65090 PMIC.
+
+Example:
+
+ tps65090-charger {
+ compatible = "ti,tps65090-charger";
+ ti,enable-low-current-chrg;
+ };
