Subject: [PATCH v3 5/8] arm64: dts: amlogic: t7: add the ethernet pinctrl nodes
Date: Sat, 10 Oct 2026 11:58:57 +0100	[thread overview]
Message-ID: <20261010105900.247342-6-tanure@linux.com> (raw)
In-Reply-To: <20261010105900.247342-1-tanure@linux.com>

The SoC brings its ethernet interface out on bank Z, but no pin groups
were described, so a board had no way to hand those pins over to the
MAC.

Describe them as the two sets a board actually needs: the nine pins the
interface always uses, and the five extra ones RGMII adds for its wider
data path.
