5 | - list of the ION heaps | |
6 | - heap name : maybe heap_sys_user@0 | |
7 | - heap id : id should be unique in the system. | |
8 | - heap base : base ddr address of the heap,0 means that | |

15 | hi6220-ion { | |
16 | compatible = "hisilicon,hi6220-ion"; | |
17 | heap_sys_user@0 { | |
18 | heap-name = "sys_user"; | |
19 | heap-id = <0x0>; | |
20 | heap-base = <0x0>; | |
21 | heap-size = <0x0>; | |
