From 62a5df451ab911421da96655fcc4d1e269ff6e2f Mon Sep 17 00:00:00 2001 From: Mantas Pucka Date: Tue, 23 Jan 2024 18:09:20 +0200 Subject: [PATCH] phy: qcom-qmp-usb: fix serdes init sequence for IPQ6018 Commit 23fd679249df ("phy: qcom-qmp: add USB3 PHY support for IPQ6018") noted that IPQ6018 init is identical to IPQ8074. Yet downstream uses separate serdes init sequence for IPQ6018. Since already existing IPQ9574 serdes init sequence is identical, just reuse it and fix failing USB3 mode in IPQ6018.
