Subject: [PATCH 1/2] arm64: dts: qcom: x1e001de-devkit: Describe USB
retimers resets pin configs
Currently, on the X Elite Devkit, the pin configuration of the reset
gpios for all three PS8830 USB retimers are left configured by the
bootloader.
Fix that by describing their pin configuration.
Fixes: 019e1ee32fec ("arm64: dts: qcom: x1e001de-devkit: Enable external DP support")
