| 41 | and "cache". |
| 42 | - reg : Address and size of L2 cache controller registers |
| 43 | - cache-size : Size of the entire L2 cache |
| 44 | - interrupts : Error interrupt of L2 controller |
| 45 | - cache-line-size : Size of L2 cache lines |
| 46 | |
| 47 | Example: |
| 48 | |
| 49 | L2: l2-cache-controller@20000 { |
| 50 | compatible = "fsl,bsc9132-l2-cache-controller", "cache"; |
| 51 | reg = <0x20000 0x1000>; |
| 52 | cache-line-size = <32>; // 32 bytes |
| 53 | cache-size = <0x40000>; // L2,256K |
| 54 | interrupts = <16 2 1 0>; |
| 55 | }; |
