Freescale L2 Cache Controller
L2 cache is present in Freescale's QorIQ and QorIQ Qonverge platforms.
The cache bindings explained below are ePAPR compliant
Required Properties:
- compatible : Should include "fsl,chip-l2-cache-controller" and "cache"
where chip is the processor (bsc9132, npc8572 etc.)
- reg : Address and size of L2 cache controller registers
- cache-size : Size of the entire L2 cache
- interrupts : Error interrupt of L2 controller
- cache-line-size : Size of L2 cache lines
Example:
L2: l2-cache-controller@20000 {
compatible = "fsl,bsc9132-l2-cache-controller", "cache";
reg = <0x20000 0x1000>;
cache-line-size = <32>; // 32 bytes
cache-size = <0x40000>; // L2,256K
interrupts = <16 2 1 0>;
};

Freescale DDR memory controller
Properties:
- compatible : Should include "fsl,chip-memory-controller" where
chip is the processor (bsc9132, mpc8572 etc.), or
"fsl,qoriq-memory-controller".
- reg : Address and size of DDR controller registers
- interrupts : Error interrupt of DDR controller
Example 1:
memory-controller@2000 {
compatible = "fsl,bsc9132-memory-controller";
reg = <0x2000 0x1000>;
interrupts = <16 2 1 8>;
};
Example 2:
ddr1: memory-controller@8000 {
compatible = "fsl,qoriq-memory-controller-v4.7",
"fsl,qoriq-memory-controller";
reg = <0x8000 0x1000>;
interrupts = <16 2 1 23>;

Required properties :
- compatible : Should be "fsl-usb2-mph" for multi port host USB
controllers, or "fsl-usb2-dr" for dual role USB controllers
or "fsl,mpc5121-usb2-dr" for dual role USB controllers of MPC5121
or "fsl,mpc5121-usb2-dr" for dual role USB controllers of MPC5121.
Wherever applicable, the IP version of the USB controller should
also be mentioned (for eg. fsl-usb2-dr-v2.2 for bsc9132).
- phy_type : For multi port host USB controllers, should be one of
"ulpi", or "serial". For dual role USB controllers, should be
one of "ulpi", "utmi", "utmi_wide", or "serial".
