Subject: [PATCH net-next v2 5/5] net: cadence: macb: enable EEE for Raspberry Pi RP1
Date: Tue, 24 Feb 2026 10:18:21 +0100	[thread overview]
Message-ID: <20260224091821.47671-6-nb@tipi-net.de> (raw)
In-Reply-To: <20260224091821.47671-1-nb@tipi-net.de>

Enable IEEE 802.3az Energy Efficient Ethernet on the Raspberry Pi 5's
RP1 southbridge by adding MACB_CAPS_EEE to its platform config.

The RP1 contains a Cadence GEM_GXL MAC (revision 0x00070109) paired
with a Broadcom BCM54213PE PHY, both of which support EEE at
1000BASE-T and 100BASE-TX.
