Subject: [PATCH v3 04/14] phy: qcom: qmp-usbc: Add USBC PHY type enum
Date: Wed, 20 Aug 2025 17:34:46 +0800	[thread overview]
Message-ID: <20250820-add-displayport-support-for-qcs615-platform-v3-4-a43bd25ec39c@oss.qualcomm.com> (raw)
In-Reply-To: <20250820-add-displayport-support-for-qcs615-platform-v3-0-a43bd25ec39c@oss.qualcomm.com>

Introduce qmp_phy_usbc_type enum and a 'type' field in qmp_phy_cfg to
differentiate between USB-only PHYs and USB/DP switchable PHYs.
