+* Qualcomm Krait L1 / L2 cache dumping device
+This is a virtual device that dumps the contents of L1 and L2 caches in the
+event of a kernel panic or a watchdog trigger.
+
+Required properties:
+- compatible:			Should be "qcom,cache_dump"
+- qcom,l1-dump-size:		Amount of memory needed for L1 dump(s), in bytes
+- qcom,l2-dump-size:		Amount of memory needed for L2 dump, in bytes
+- qcom,memory-reservation-size: Combined reserved memory for the dump buffers
+- qcom,memory-reservation-type: Type of memory to be reserved
+
+Optional properties:
+- qcom,use-imem-dump-offset: If specified, store cache dump buffer addresses
+  in IMEM rather than using the memory dump reservation table.
+
+Example:
+	qcom,cache_dump {
+		compatible = "qcom,cache_dump";
+		qcom,l1-dump-size = <0x100000>;
+		qcom,l2-dump-size = <0x400000>;
+		qcom,memory-reservation-type = "EBI1";
+		qcom,memory-reservation-size = <0x500000>;
+	};

+Qualcomm's QPNP PMIC Battery Management System driver
+
+QPNP PMIC BMS provides interface to clients to read properties related
+to the battery. It's main function is to calculate the State of Charge (SOC),
+a 0-100 percentage representing the amount of charge left in the battery.
+
+BMS node
+
+Required properties:
+- compatible : should be "qcom,qpnp-bms" for the BM driver.
+- reg : offset and length of the PMIC BMS register map.
+- interrupts : the interrupt mappings for bms.
+		The format should be
+		<slave-id peripheral-id interrupt-number>.
+- interrupt-names : names for the mapped bms interrupt
+		The following interrupts are required:
+		0 : vsense_for_r
+		1 : vsense_avg
+		2 : sw_cc_thr
+		3 : ocv_thr
+		4 : charge_begin
+		5 : good_ocv
+		6 : ocv_for_r
+		7 : cc_thr
+- qcom,bms-r-sense-mohm : sensor resistance in in milli-ohms.
+- qcom,bms-v-cutoff-uv : cutoff voltage where the battery is considered dead in
+			micro-volts.
+- qcom,bms-max-voltage-uv : maximum voltage for the battery in micro-volts.
+- qcom,bms-r-conn-mohm : connector resistance in milli-ohms.
+- qcom,bms-shutdown-soc-valid-limit : If the ocv upon restart is within this
+			distance of the shutdown ocv, the BMS will try to force
+			the new SoC to the old one to provide charge continuity.
+			That is to say,
+				if (abs(shutdown-soc - current-soc) < limit)
+				then use old SoC.
+- qcom,bms-adjust-soc-low-threshold : The low threshold for the "flat portion"
+			of the charging curve. The BMS will not adjust SoC
+			based on voltage during this time.
+- qcom,bms-adjust-soc-high-threshold :  The high threshold for the "flat
+			portion" of the charging curve. The BMS will not
+			adjust SoC based on voltage during this time.
+- qcom,bms-chg-term-ua : current in micro-amps when charging is considered done.
+			As soon as current passes this point, charging is
+			stopped.
+
+Example:
+	bms@4000 {
+		#address-cells = <1>;
+		#size-cells = <1>;
+
+		compatible = "qcom,qpnp-bms";
+		reg = <0x4000 0x100>;
