Hi Andrew,<br>
<br>
This is Jacky from ASPEED.</div>
<div style="margin-top: 1em; margin-bottom: 1em; font-family: Consolas, Courier, monospace; font-size: 12pt; color: rgb(0, 0, 0);" class="elementToProof">
Last year, I submitted a series of patches to add a new compatible string <code>"aspeed,ast2700-mdio"</code>. At that time, the feedback I received was that if there were no functional changes, a new compatible string would not be necessary.</div>
<div style="margin-top: 1em; margin-bottom: 1em; font-family: Consolas, Courier, monospace; font-size: 12pt; color: rgb(0, 0, 0);" class="elementToProof">
Recently, we are submitting the AST2700 platform support to the Linux kernel. In the following discussion thread, it appears that the MDIO driver might need a new compatible string for the AST2700 platform:<br>

<div style="margin-top: 1em; margin-bottom: 1em; font-family: Consolas, Courier, monospace; font-size: 12pt; color: rgb(0, 0, 0);" class="elementToProof">
I would like to confirm whether this case should be submitted separately to <b>net-next</b>, and in general, if there are no hardware or design changes, is it still required to introduce a new compatible string?</div>

Thank you for your guidance.</div>

If they are identical, why do you need a new compatible?<br>
