Subject: [PATCH v8 phy-next 22/31] drm: bridge: cdns-mhdp8546: use consumer API for getting PHY bus width
Date: Tue, 5 May 2026 13:05:14 +0300 [thread overview]
Message-ID: <20260505100523.1922388-23-vladimir.oltean@nxp.com> (raw)
In-Reply-To: <20260505100523.1922388-1-vladimir.oltean@nxp.com>
The Cadence MHDP8546 DP bridge driver gets the PHY bus_width attribute
(holding number of lanes) directly, but doing this will no longer be
possible after the definition of struct phy is hidden from consumers.
Use the phy_get_bus_width() API function designed specifically for
consumers.
