+* ARM Generic Interrupt Controller
+
+ARM SMP cores are often associated with a GIC, providing per processor
+interrupts (PPI), shared processor interrupts (SPI) and software
+generated interrupts (SGI).
+
+Primary GIC is attached directly to the CPU and typically has PPIs and SGIs.
+Secondary GICs are cascaded into the upward interrupt controller and do not
+have PPIs or SGIs.
+
+Main node required properties:
+
+- compatible : should be one of:
+ "arm,cortex-a9-gic"
+ "arm,arm11mp-gic"
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode an
+ interrupt source. The type shall be a <u32> and the value shall be 3.
+
+ The 1st cell is the interrupt type; 0 for SPI interrupts, 1 for PPI
+ interrupts.
+
+ The 2nd cell contains the interrupt number for the interrupt type.
+ SPI interrupts are in the range [0-987]. PPI interrupts are in the
+ range [0-15].
+
+ The 3rd cell is the flags, encoded as follows:
+ bits[3:0] trigger type and level flags.
+ 1 = low-to-high edge triggered
+ 2 = high-to-low edge triggered
+ 4 = active high level-sensitive
+ 8 = active low level-sensitive
+ bits[15:8] PPI interrupt cpu mask. Each bit corresponds to each of
+ the 8 possible cpus attached to the GIC. A bit set to '1' indicated
+ the interrupt is wired to that CPU. Only valid for PPI interrupts.
+
+- reg : Specifies base physical address(s) and size of the GIC registers. The
+ first region is the GIC distributor register base and size. The 2nd region is
+ the GIC cpu interface register base and size.
+
+Optional
+- interrupts : Interrupt source of the parent interrupt controller. Only
+ present on secondary GICs.
+
+Example:
+
+ intc: interrupt-controller@fff11000 {
+ compatible = "arm,cortex-a9-gic";
+ #interrupt-cells = <3>;
+ #address-cells = <1>;
+ interrupt-controller;
+ reg = <0xfff11000 0x1000>,
+ <0xfff10100 0x100>;
+ };

+* Qualcomm MSM UART
+
+Required properties:
+- compatible :
+ - "qcom,msm-uart", and one of "qcom,msm-hsuart" or
+ "qcom,msm-lsuart".
+- reg : offset and length of the register set for the device
+ for the hsuart operating in compatible mode, there should be a
+ second pair describing the gsbi registers.
+- interrupts : should contain the uart interrupt.
+
+There are two different UART blocks used in MSM devices,
+"qcom,msm-hsuart" and "qcom,msm-lsuart". The msm-serial driver is
+able to handle both of these, and matches against the "qcom,msm-uart"
+as the compatibility.
+
+The registers for the "qcom,msm-hsuart" device need to specify both
+register blocks, even for the common driver.
+
+Example:
+
+ uart@19c400000 {
+ compatible = "qcom,msm-hsuart", "qcom,msm-uart";
+ reg = <0x19c40000 0x1000>,
+ <0x19c00000 0x1000>;
+ interrupts = <195>;
+ };
