Subject: [PATCH v2 2/3] dt-bindings: phy: qcom,sc8280xp-qmp-usb43dp-phy: Document the Nord QMP PHY
Date: Wed, 16 Sep 2026 20:30:52 +0200 [thread overview]
Message-ID: <20260916-nord-usb-phy-v2-2-2c8461bb30e6@oss.qualcomm.com> (raw)
In-Reply-To: <20260916-nord-usb-phy-v2-0-2c8461bb30e6@oss.qualcomm.com>
Add a compatible for the USB3+DP combo QMP PHY found on the Qualcomm Nord
SoC. The PHY sits behind a GDSC, so also allow (and require) power-domains
for it.
The block gets a standalone compatible rather than a fallback to an
existing one, because it is not register-compatible with any PHY already
described here. Its USB3 and DP initialisation sequences do match sm8550,
but Nord places the sub-blocks at different offsets within the PHY: it
exposes a dedicated USB3_PCS_AON region at 0x1e00, which sm8550 does not
have at all. Falling back to sm8550 - or to any other entry - would make
the driver program the wrong addresses.
