Subject: [PATCH] phy: qcom-qusb2: Update the phy settings for IPQ5424
Date: Mon, 07 Apr 2025 19:51:17 +0530	[thread overview]
Message-ID: <20250407-revert_hs_phy_settings-v1-1-ec94e316ea19@oss.qualcomm.com> (raw)

Update the phy settings for IPQ5424 to meet compliance requirements.
The current settings do not meet the requirements, and the design team
has requested to use the settings used for IPQ6018.

Revert the commit 9c56a1de296e ("phy: qcom-qusb2: add QUSB2 support for
IPQ5424") and reuse the IPQ6018 settings.

Fixes: 9c56a1de296e ("phy: qcom-qusb2: add QUSB2 support for IPQ5424")
