This is an automatically generated commit which aids following Kernel patch history, as git will see the move and copy as a rename thus defeating the purpose.

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.
