It is not only the PHC clock that stops. Rather, it is the entire ethernet building block in the SOC that is disabled, including the PHC.Sure, but why does the driver do that?That is a good question. I tried to understand the clock infrastructure of the imx8 but it looks quite complicated. I cannot find the point where all the stuff is disabled.
But the explanation why it is currently disabled that way can be found in the commit 91c0d987a9788dcc5fe26baafd73bf9242b68900. -- Heiko
