+title: Apple ARM Machine Device Tree Bindings
+

+
+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

+description: |
+  Arm Embedded Trace Extension(ETE) is a per CPU trace component that
+  allows tracing the CPU execution. It overlaps with the CoreSight ETMv4
+  architecture and has extended support for future architecture changes.
+  The trace generated by the ETE could be stored via legacy CoreSight
+  components (e.g, TMC-ETR) or other means (e.g, using a per CPU buffer
+  Arm Trace Buffer Extension (TRBE)). Since the ETE can be connected to
+  legacy CoreSight components, a node must be listed per instance, along
+  with any optional connection graph as per the coresight bindings.
+  See bindings/arm/coresight.txt.

+description: |
+  Arm Trace Buffer Extension (TRBE) is a per CPU component
+  for storing trace generated on the CPU to memory. It is
+  accessed via CPU system registers. The software can verify
+  if it is permitted to use the component by checking the
+  TRBIDR register.
