  1. * Andestech L2 cache Controller
  2. The level-2 cache controller plays an important role in reducing memory latency
  3. for high performance systems, such as thoese designs with AndesCore processors.
  4. Level-2 cache controller in general enhances overall system performance
  5. signigicantly and the system power consumption might be reduced as well by
  6. reducing DRAM accesses.
  7. This binding specifies what properties must be available in the device tree
  8. representation of an Andestech L2 cache controller.
  9. Required properties:
  10. - compatible:
  11. Usage: required
  12. Value type: <string>
  13. Definition: "andestech,atl2c"
  14. - reg : Physical base address and size of cache controller's memory mapped
  15. - cache-unified : Specifies the cache is a unified cache.
  16. - cache-level : Should be set to 2 for a level 2 cache.
  17. * Example
  18. cache-controller@e0500000 {
  19. compatible = "andestech,atl2c";
  20. reg = <0xe0500000 0x1000>;
  21. cache-unified;
  22. cache-level = <2>;
  23. };
