Subject: [PATCH v2 8/9] arm64: dts: qcom: kodiak: Align EUD node with binding
Date: Mon, 26 Jan 2026 15:38:29 -0800	[thread overview]
Message-ID: <20260126233830.2193816-9-elson.serrao@oss.qualcomm.com> (raw)
In-Reply-To: <20260126233830.2193816-1-elson.serrao@oss.qualcomm.com>

The EUD node does not match the current binding and maps USB endpoints
to the secondary controller. This SoC supports EUD only on the primary
High-Speed USB path. The binding also requires a per-path PHY reference.

Model the primary UTMI path as a child node with the required PHY and an
empty ports graph. Leave endpoint mapping to board DTS files, and remove
the secondary mapping and associated ports so the description conforms
to the binding.
