[ Upstream commit 942e47a ] property "qcom,tune-usb2-preem" is for EUSB2_TUNE_USB2_PREEM property "qcom,tune-usb2-amplitude" is for EUSB2_TUNE_IUSB2 The downstream correspondence is as follows: EUSB2_TUNE_USB2_PREEM: Tx pre-emphasis tuning EUSB2_TUNE_IUSB2: HS trasmit amplitude EUSB2_TUNE_SQUELCH_U: Squelch detection threshold EUSB2_TUNE_HSDISC: HS disconnect threshold EUSB2_TUNE_EUSB_SLEW: slew rate Fixes: 31bc94d ("phy: qualcomm: phy-qcom-eusb2-repeater: Don't zero-out registers") Signed-off-by: Pengyu Luo <mitltlatltl@gmail.com> Reviewed-by: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com> Reviewed-by: Luca Weiss <luca.weiss@fairphone.com> Link: https://lore.kernel.org/r/20250812093957.32235-1-mitltlatltl@gmail.com Signed-off-by: Vinod Koul <vkoul@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>
