+Interlaken Look-Aside Controller (LAC) Node
+
+DESCRIPTION
+
+The Interlaken is a narrow, high speed channelized chip-to-chip interface. To
+facilitate interoperability between a data path device and a look-aside
+co-processor, the Interlaken Look-Aside protocol is defined for short
+transaction-related transfers. Although based on the Interlaken protocol,
+Interlaken Look-Aside is not directly compatible with Interlaken and can be
+considered a different operation mode.
+
+The Interlaken LA controller connects internal platform to Interlaken serial
+interface. It accepts LA command through software portals, which are system
+memory mapped 4KB spaces. The LA commands are then translated into the
+Interlaken control words and data words, which are sent on TX side to TCAM
+through SerDes lanes.
+
+There are two 4KiB spaces defined within the LAC global register memory map.
+There is a full register set at 0x0000-0x0FFF (also known as the "hypervisor"
+version), and a subset at 0x1000-0x1FFF. The former is a superset of the
+latter, and includes certain registers that should not be accessible to
+partitioned software. Separate nodes are used for each region, with a phandle
+linking the hypervisor node to the normal operating node.
+
+PROPERTIES
+
+ - compatible
+ Usage: required
+ Value type: <string>
+ Definition: Must include "fsl,interlaken-lac". This represents only
+ those LAC CCSR registers not protected in partitioned
+ software. The version of the device is determined by the LAC
+ IP Block Revision Register (IPBRR0) at offset 0x0BF8.
+
+ Table of correspondences between IPBRR0 values and example
+ chips:
+ Value Device
+ ----------- -------
+ 0x02000100 T4240
+
+ The Hypervisor node has a different compatible. It must include
+ "fsl,interlaken-lac-hv". This node represents the protected
+ LAC register space and is required except inside a partition
+ where access to the hypervisor node is to be denied.
+
+ - fsl,non-hv-node
+ Usage: required in "fsl,interlaken-lac-hv"
+ Value type: <phandle>
+ Definition: Points to the non-protected LAC CCSR mapped register space
+ node.
+
+ - reg
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: A standard property. The first resource represents the
+ Interlaken LAC configuration registers.
+
+ - interrupts:
+ Usage: required in non-hv node only
+ Value type: <prop-encoded-array>
+ Definition: Interrupt mapping for Interlaken LAC error IRQ.

+EXAMPLE
+ lac: lac@229000 {

+ reg = <0x229000 0x1000>;

+Interlaken Look-Aside Controller (LAC) Software Portal Container Node
+
+DESCRIPTION
+The Interlaken Look-Aside Controller (LAC) utilizes Software Portals to accept
+Interlaken Look-Aside (ILA) commands. The Interlaken LAC software portal
+memory map occupies 128KB of memory space. The software portal memory space is
+intended to be cache-enabled. WIMG for each software space is required to be
+0010 if stashing is enabled; otherwise, WIMG can be 0000 or 0010.
+
+PROPERTIES
+
+ - #address-cells
+ Usage: required
+ Value type: <u32>
+ Definition: A standard property. Must have a value of 1.
+
+ - #size-cells
+ Usage: required
+ Value type: <u32>
+ Definition: A standard property. Must have a value of 1.
+
+ - compatible
+ Usage: required
+ Value type: <string>
+ Definition: Must include "fsl,interlaken-lac-portals"
+
+ - ranges
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: A standard property. Specifies the address and length
+ of the LAC portal memory space.

+Interlaken Look-Aside Controller (LAC) Software Portals Child Nodes
+
+DESCRIPTION
+There are up to 24 available software portals with each software portal
+requiring 4KB of consecutive memory within the software portal memory mapped
+space.
+
+PROPERTIES
+
+ - compatible
+ Usage: required
+ Value type: <string>
+ Definition: Must include "fsl,interlaken-lac-portal-vX.Y" where X is
+ the Major version (IP_MJ) found in the LAC IP Block Revision
+ Register (IPBRR0), at offset 0x0BF8, and Y is the Minor version
+ (IP_MN).
+
+ Table of correspondences between version values and example chips:
+ Value Device
+ ------ -------
+ 1.0 T4240
+
+ - reg
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: A standard property. The first resource represents the
+ Interlaken LAC software portal registers.
+
+ - fsl,liodn
+ Value type: <u32>
+ Definition: The logical I/O device number (LIODN) for this device. The
+ LIODN is a number expressed by this device and used to perform
+ look-ups in the IOMMU (PAMU) address table when performing
+ DMAs. This property is automatically added by u-boot.
