Subject: [PATCH 2/3] dt-bindings: phy: qcom,snps-eusb2-phy: Add Nord bus clock
Date: Thu,  8 Oct 2026 09:50:16 +0800	[thread overview]
Message-ID: <20261008015017.3359804-3-shengchao.guo@oss.qualcomm.com> (raw)
In-Reply-To: <20261008015017.3359804-1-shengchao.guo@oss.qualcomm.com>

On Nord, the eUSB2 PHY registers are reached through the AHB2PHY_0
bridge, which is gated by NE_GCC_AHB2PHY_CLK. Allow an optional
second "bus" clock for the AHB2PHY bridge, require it for
qcom,nord-snps-eusb2-phy, and keep other compatibles at the single
"ref" clock.
