Subject: [PATCH v9 21/38] phy: rockchip: usbdp: Factor out lane_mux_sel setup
Date: Thu, 02 Jul 2026 01:35:59 +0200 [thread overview]
Message-ID: <20260702-rockchip-usbdp-cleanup-v9-21-e31efbb62d2e@collabora.com> (raw)
In-Reply-To: <20260702-rockchip-usbdp-cleanup-v9-0-e31efbb62d2e@collabora.com>
Avoid describing the USB+DP lane_mux_sel logic twice by introducing
a helper function to reduce code duplication.
