Subject: [PATCH 063/323] net: stmmac: sun8i: Fix reboot issue with ethernet on
|
|
Orange Pi 3
|
|
|
|
We disable both phy regulators before reboot, so that they are in a
|
|
known state on the next boot. This should be done in u-boot, but
|
|
it doesn't support AXP806 yet, so we shut it down in kernel.
