Subject: Re: [PATCH] Changes phy configuration to expose sata in place of
usb3 on quartz64-a board
Hello, I'm reviewing the notes you made me on the review.
To tell all the truth, I derived the DTS from an existing one by modifying a small portion of it.
In the end, your notes are for the already existing DTS.
To address the notes in your message and spare future work, I decided to refactor the rk3566-quartz64-a DTS.
I will post another patch briefly with the new version.
For the moment, thank you for the review.
Regards
Alessandro
