[PATCH net-next v2 08/10] net: stmmac: platform: support parsing safety irqs from DT

From: Jisheng Zhang
Date: Mon Aug 07 2023 - 12:55:00 EST


The snps dwmac IP may support safety features, and those Safety
Feature Correctible Error and Uncorrectible Error irqs may be
separate irqs. Add support to parse the safety irqs from DT.
