On some devices, the bootloader suspends the PHY before booting the OS. Not having a resume callback wired up is a problem in such situations since it is then never resumed. This behavior was observed with a Huawei enterprise WLAN access point.
The BCM54612E ethernet PHY supports IDDQ-SR. Therefore wire-up the suspend and resume callbacks to point to bcm54xx_suspend() and bcm54xx_resume().
The same wire-up has been done in commit 38b6a9073007 ("net: phy: broadcom: Wire suspend/resume for BCM50610 and BCM50610M") for two PHYs also supporting IDDQ-SR.
