[PATCH net-next v2 1/2] dt-bindings: net: marvell,aquantia: add properties to override MDI_CFG

From: Daniel Golle
Date: Wed Aug 28 2024 - 18:52:25 EST


Usually the MDI pair order reversal configuration is defined by
bootstrap pin MDI_CFG. Some designs, however, require overriding the MDI
pair order and force either normal or reverse order.

Add mutually exclusive properties 'marvell,force-mdi-order-normal' and
'marvell,force-mdi-order-reverse' for that purpose.

v2: enforce mutually exclusive relationship of the two new properties in
dt-schema.
