Subject: [PATCH 1/8] phy: qcom: qmp-usb-legacy: drop single-lane support
Date: Tue, 09 Jan 2024 05:03:59 +0200	[thread overview]
Message-ID: <20240109-phy-qmp-merge-common-v1-1-572899a14318@linaro.org> (raw)
In-Reply-To: <20240109-phy-qmp-merge-common-v1-0-572899a14318@linaro.org>

All PHYs supported by usb-legacy have two lanes. Drop support for
single-lane configuration.
