and "cache".
- 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>;
};
