I'd like to clarify that: Without this patch the writel the patch is modifying will clear the PHY_ID bit. But despite that the system works if at some point (uboot) set the PHY_ID bit? > > Fixes: 9a24e1ff4326 ("net: mdio: add amlogic gxl mdio mux support"); I don't think you need to resend because of this, but the correct syntax is as follows.
