[PATCH v8 01/12] dt-bindings: phy: Add QMP USB3+DP PHY for QCS615

[Xiangxu Yin via B4 Relay <devnull+xiangxu.yin.oss.qualcomm.com@kernel.org>]

From: Xiangxu Yin <xiangxu.yin@oss.qualcomm.com>

Add device tree binding documentation for the Qualcomm QMP USB3+DP PHY
on QCS615 Platform. This PHY supports both USB3 and DP functionality
over USB-C, with PHY mode switching capability. It does not support
combo mode.
