| Tom Rini | 53633a8 | 2024-02-29 12:33:36 -0500 | [diff] [blame] | 1 | Some properties contain an ordered list of 1 or more datum which are |
| 2 | normally accessed by index. However, some devices will have multiple |
| 3 | values which are more naturally accessed by name. Device nodes can |
| 4 | include a supplemental property for assigning names to each of the list |
| 5 | items. The names property consists of a list of strings in the same |
| 6 | order as the data in the resource property. |
| 7 | |
| 8 | The following supplemental names properties are defined. |
| 9 | |
| 10 | Resource Property Supplemental Names Property |
| 11 | ----------------- --------------------------- |
| 12 | reg reg-names |
| 13 | clocks clock-names |
| 14 | interrupts interrupt-names |
| 15 | |
| 16 | Usage: |
| 17 | |
| 18 | The -names property must be used in conjunction with the normal resource |
| 19 | property. If not it will be ignored. |
| 20 | |
| 21 | Examples: |
| 22 | |
| 23 | l4-abe { |
| 24 | compatible = "simple-bus"; |
| 25 | #address-cells = <2>; |
| 26 | #size-cells = <1>; |
| 27 | ranges = <0 0 0x48000000 0x00001000>, /* MPU path */ |
| 28 | <1 0 0x49000000 0x00001000>; /* L3 path */ |
| 29 | mcasp { |
| 30 | compatible = "ti,mcasp"; |
| 31 | reg = <0 0x10 0x10>, <0 0x20 0x10>, |
| 32 | <1 0x10 0x10>, <1 0x20 0x10>; |
| 33 | reg-names = "mpu", "dat", |
| 34 | "dma", "dma_dat"; |
| 35 | interrupts = <11>, <12>; |
| 36 | interrupt-names = "rx", "tx"; |
| 37 | }; |
| 38 | |
| 39 | timer { |
| 40 | compatible = "ti,timer"; |
| 41 | reg = <0 0x40 0x10>, <1 0x40 0x10>; |
| 42 | reg-names = "mpu", "dma"; |
| 43 | }; |
| 44 | }; |
| 45 | |
| 46 | |
| 47 | usb { |
| 48 | compatible = "ti,usb-host"; |
| 49 | reg = <0x4a064000 0x800>, <0x4a064800 0x200>, |
| 50 | <0x4a064c00 0x200>; |
| 51 | reg-names = "config", "ohci", "ehci"; |
| 52 | interrupts = <14>, <15>; |
| 53 | interrupt-names = "ohci", "ehci"; |
| 54 | }; |
