[PATCH net] net: dsa: bcm_sf2: Prevent GPHY shutdown for kexec'd kernels

2016-10-20 Thread Florian Fainelli
For a kernel that is being kexec'd we re-enable the integrated GPHY in order for the subsequent MDIO bus scan to succeed and properly bind to the bcm7xxx PHY driver. If we did not do that, the GPHY would be shut down by the time the MDIO driver is probing the bus, and it would fail to read the corr
