net: phy: broadcom: Save PHY counters during suspend

2026-05-07T15:36:47+00:00

The PHY counters can be lost if the PHY is reset during suspend. We need to save the values into the shadow counters or the accounting will be incorrect over multiple suspend and resume cycles.

net: phy: broadcom: implement .disable_autonomous_eee for BCM54xx

2026-04-12T18:33:23+00:00

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.

net: phy: bcm54811: Fix GMII/MII/MII-Lite selection

2025-10-14T00:36:20+00:00

The Broadcom bcm54811 is hardware-strapped to select among RGMII and GMII/MII/MII-Lite modes. However, the corresponding bit, RGMII Enable in Miscellaneous Control Register must be also set to select desired RGMII or MII(-lite)/GMII mode.

net: phy: bcm5481x: MII-Lite activation

2025-07-10T02:32:31+00:00

Broadcom PHYs featuring the BroadR-Reach two-wire link mode are usually capable to operate in simplified MII mode, without TXER, RXER, CRS and COL signals as defined for the MII. The absence of COL signal makes half-duplex link modes impossible, however, the BroadR-Reach modes are all full-duplex only. Depending on the IC encapsulation, there exist MII-Lite-only PHYs such as bcm54811 in MLP. The PHY itself is hardware-strapped to select among multiple RGMII and MII-Lite modes, but the MII-Lite mode must be also activated by software. Add MII-Lite activation for bcm5481x PHYs.
