[PATCH 05/17] dt-bindings: interrupt-controller: apple,aic2: Add apple,t8112-aic compatible

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The Apple M2 SoC uses AICv2 and is compatible with the existing driver.
Add its per-SoC compatible.
Since multi-die versions of the M2 are not expected decrease
'#interrupt-cells' to 3 for apple,t8112-aic. This is seamlessly handled
inside the driver.

Signed-off-by: Janne Grunau <j@xxxxxxxxxx>

---
This trivial dt-bindings update should be merged through the asahi-soc
tree to ensure validation of the Apple M2 (t8112) devicetrees in this
series.
