Subject: [PATCH v2 2/6] dt-bindings: phy: qcom,msm8998-qmp-usb3-phy: add TCSR registers
Date: Wed, 17 Jan 2024 16:04:23 +0200	[thread overview]
Message-ID: <20240117-usbc-phy-vls-clamp-v2-2-a950c223f10f@linaro.org> (raw)
In-Reply-To: <20240117-usbc-phy-vls-clamp-v2-0-a950c223f10f@linaro.org>

The QMP USB PHYs on msm8998, qcm2290 and some other platforms don't have
the PCS_MISC_CLAMP_ENABLE register. Instead they need to toggle the
register in the TCSR space. Declare the registers accessible through the
TCSR space.
