-* NVIDIA Tegra APB DMA controller
-
-Required properties:
-- compatible: Should be "nvidia,<chip>-apbdma"
-- reg: Should contain DMA registers location and length. This should include
-  all of the per-channel registers.
-- interrupts: Should contain all of the per-channel DMA interrupts.
-- clocks: Must contain one entry, for the module clock.
-  See ../clocks/clock-bindings.txt for details.
-- resets : Must contain an entry for each entry in reset-names.
-  See ../reset/reset.txt for details.
-- reset-names : Must include the following entries:
-  - dma
-- #dma-cells : Must be <1>. This dictates the length of DMA specifiers in
-  client nodes' dmas properties. The specifier represents the DMA request
-  select value for the peripheral. For more details, consult the Tegra TRM's
-  documentation of the APB DMA channel control register REQ_SEL field.

-

+description:
+  The NVIDIA Tegra APB DMA controller is a hardware component that
+  enables direct memory access (DMA) on Tegra systems. It facilitates
+  data transfer between I/O devices and main memory without constant

-NVIDIA Legacy Interrupt Controller
-
-All Tegra SoCs contain a legacy interrupt controller that routes
-interrupts to the GIC, and also serves as a wakeup source. It is also
-referred to as "ictlr", hence the name of the binding.
-
-The HW block exposes a number of interrupt controllers, each
-implementing a set of 32 interrupts.
-
-Required properties:
-
-- compatible : should be: "nvidia,tegra<chip>-ictlr". The LIC on
-  subsequent SoCs remained backwards-compatible with Tegra30, so on
-  Tegra generations later than Tegra30 the compatible value should
-  include "nvidia,tegra30-ictlr".	
-- reg : Specifies base physical address and size of the registers.
-  Each controller must be described separately (Tegra20 has 4 of them,
-  whereas Tegra30 and later have 5).
-- interrupt-controller : Identifies the node as an interrupt controller.
-- #interrupt-cells : Specifies the number of cells needed to encode an
-  interrupt source. The value must be 3.
-
-Notes:
-
-- Because this HW ultimately routes interrupts to the GIC, the
-  interrupt specifier must be that of the GIC.
-- Only SPIs can use the ictlr as an interrupt parent. SGIs and PPIs
-  are explicitly forbidden.
-
-Example:
-
-	ictlr: interrupt-controller@60004000 {
-		compatible = "nvidia,tegra20-ictlr", "nvidia,tegra-ictlr";
-		reg = <0x60004000 64>,
-		      <0x60004100 64>,
-		      <0x60004200 64>,
-		      <0x60004300 64>;
-		interrupt-controller;
-		#interrupt-cells = <3>;
-		interrupt-parent = <&intc>;
