| description: | |
| ARM platforms using SoCs designed by Apple Inc., branded "Apple Silicon". |
| |
| This currently includes devices based on the "M1" SoC: |
| |
| - Mac mini (M1, 2020) |
| - MacBook Pro (13-inch, M1, 2020) |
| - MacBook Air (M1, 2020) |
| - iMac (24-inch, M1, 2021) |
| |
| And devices based on the "M1 Pro" and "M1 Max" SoCs: |
| |
| - MacBook Pro (14-inch, M1 Pro, 2021) |
| - MacBook Pro (14-inch, M1 Max, 2021) |
| - MacBook Pro (16-inch, M1 Pro, 2021) |
| - MacBook Pro (16-inch, M1 Max, 2021) |
| |
| The compatible property should follow this format: |
| |
| compatible = "apple,<targettype>", "apple,<socid>", "apple,arm-platform"; |
| |
| <targettype> represents the board/device and comes from the `target-type` |
| property of the root node of the Apple Device Tree, lowercased. It can be |
| queried on macOS using the following command: |
| |
| $ ioreg -d2 -l | grep target-type |
| |
| <socid> is the lowercased SoC ID. Apple uses at least *five* different |
| names for their SoCs: |
| |
| - Marketing name ("M1") |
| - Internal name ("H13G") |
| - Codename ("Tonga") |
| - SoC ID ("T8103") |
| - Package/IC part number ("APL1102") |
| |
| Devicetrees should use the lowercased SoC ID, to avoid confusion if |
| multiple SoCs share the same marketing name. This can be obtained from |
| the `compatible` property of the arm-io node of the Apple Device Tree, |
| which can be queried as follows on macOS: |
| |
| $ ioreg -n arm-io | grep compatible |
