[PATCH] phy: qualcomm: phy-qcom-eusb2-repeater: fix override properties

From: Pengyu Luo
Date: Tue Aug 12 2025 - 05:42:34 EST


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: 31bc94de7602 ("phy: qualcomm: phy-qcom-eusb2-repeater: Don't zero-out registers")
