[PATCH net-next v2 1/2] dt-bindings: net: dsa: realtek: add RTL8365MB power supplies
From: Oleksij Rempel
Date: Tue Aug 11 2026 - 07:42:08 EST
Document the RTL8365MB power rails as optional supplies. They are optional
because the rails are often always-on; some designs break them out for
granular hwmon monitoring and regulator control.
They are scoped to realtek,rtl8365mb: different Realtek switch families use
different power-rail naming schemes, so these rails do not apply to other
families such as realtek,rtl8366rb (VDDA/VDD_CORE/VDDIO/...).
