Subject: [PATCH v4 1/4] dt-bindings: phy: qcom,sc8280xp-qmp-pcie-phy: Update pcie phy bindings
Date: Fri, 18 Jul 2025 15:12:04 +0800	[thread overview]
Message-ID: <20250718071207.160988-2-ziyue.zhang@oss.qualcomm.com> (raw)
In-Reply-To: <20250718071207.160988-1-ziyue.zhang@oss.qualcomm.com>

The gcc_aux_clk is required by the PCIe controller but not by the PCIe
PHY. In PCIe PHY, the source of aux_clk used in low-power mode should
be gcc_phy_aux_clk. Hence, remove gcc_aux_clk and replace it with
gcc_phy_aux_clk.

Removed the phy_aux clock from the PCIe PHY binding as it is no longer
used by any instance.

Fixes: fd2d4e4c1986 ("dt-bindings: phy: qcom,qmp: Add sa8775p QMP PCIe PHY")
