This patch series is for R-Car Gen3 Salvator-XS boards. If we do
the following method, the phy cannot link up correctly.
1) Kernel boots by using initramfs.
--> No open the nic, so phy_device_register() and phy_probe()
deasserts the reset.
2) Kernel enters the suspend.
--> So, keep the reset signal as deassert.
--> On R-Car Salvator-XS board, unfortunately, the board power is
turned off.
3) Kernel returns from suspend.
4) ifconfig eth0 up
--> Then, since edge signal of the reset doesn't happen,
it cannot link up.
5) ifconfig eth0 down
6) ifconfig eth0 up
--> In this case, it can link up.
Changes from v2:
- Rebase on the latest net-next.
- More generic code instead of micrel phy only code
(https://www.spinics.net/lists/netdev/msg540462.html).
So, I marked this patch series as RFT.
Changes from v1 (as RFC):
- No remove the current code of phy_device.c to avoid any side effects.
- Fix the mdio_bus_phy_resume() in phy_device.c.
- Add toggling the phy reset in micrel.c if the PHY is not attached.
