[PATCH v2 2/3] dt-bindings: net: meson-dwmac: add T7 support
From: Xianwei Zhao via B4 Relay
Date: Thu Sep 24 2026 - 01:52:11 EST
From: Xianwei Zhao <xianwei.zhao@xxxxxxxxxxx>
Add the T7 compatible to the Meson DWMAC binding.
The T7 DWMAC controller requires the following compatible combination:
amlogic,t7-dwmac
amlogic,meson-axg-dwmac
snps,dwmac-4.00
Add a conditional schema check to enforce this compatible combination
when amlogic,t7-dwmac is used.
