====================
net: bcmgenet: integrated GPHY power up/down

This patch series implements integrated Gigabit PHY power up/down, which allows
us to save close to 300mW on some designs when the Gigabit PHY is known to be
unused (e.g: during bcmgenet_close or bcmgenet_suspend not doing Wake-on-LAN).

Changes in v2:

- drop an extra bcmgenet_ext_readl in bcmgenet_phy_power_set
