From bcb3e89fc0ecbe7a2b7ce614b72deda39083ac74 Mon Sep 17 00:00:00 2001 From: Nicolai Buchwitz Date: Mon, 6 Apr 2026 09:13:08 +0200 Subject: net: phy: broadcom: implement .disable_autonomous_eee for BCM54xx Implement the .disable_autonomous_eee callback for the BCM54210E. In AutogrEEEn mode the PHY manages EEE autonomously. Clearing the AutogrEEEn enable bit in MII_BUF_CNTL_0 switches the PHY to Native EEE mode.
