Subject: [PATCH v3 1/1] arm64: dts: qcom: ipq6018: fix clock rates for GCC_USB0_MOCK_UTMI_CLK
Date: Mon, 18 Dec 2023 23:08:05 +0800

The downstream QSDK kernel [1] and GCC_USB1_MOCK_UTMI_CLK are both 24MHz.
Adjust GCC_USB0_MOCK_UTMI_CLK to 24MHz to avoid the following error:

clk: couldn't set gcc_usb0_mock_utmi_clk clk rate to 20000000 (-22), current rate: 24000000
