Subject: [PATCH v4 02/18] dt-bindings: arm: apple: Add bindings for Apple ARM platforms
Date: Fri, 2 Apr 2021 18:05:26 +0900 [thread overview]
Message-ID: <20210402090542.131194-3-marcan@marcan.st> (raw)
In-Reply-To: <20210402090542.131194-1-marcan@marcan.st>
This introduces bindings for all three 2020 Apple M1 devices:
* apple,j274 - Mac mini (M1, 2020)
* apple,j293 - MacBook Pro (13-inch, M1, 2020)
* apple,j313 - MacBook Air (M1, 2020)

+description: |
+ ARM platforms using SoCs designed by Apple Inc., branded "Apple Silicon".
+
+ This currently includes devices based on the "M1" SoC, starting with the
+ three Mac models released in late 2020:
+
+ - Mac mini (M1, 2020)
+ - MacBook Pro (13-inch, M1, 2020)
+ - MacBook Air (M1, 2020)
+
+ 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
+
