[ Upstream commit 942e47ab228c7dd27c2ae043c17e7aab2028082c ]
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
