Specifically the BCM54210E/B50212E are capable of supporting Wake-on-LAN using an external pin typically wired up to a system's GPIO. These PHY operate a programmable Ethernet MAC destination address comparator which will fire up an interrupt whenever a match is received. Because of that, it was necessary to introduce patch #1 which allows the PHY driver's ->suspend() routine to be called unconditionally. This is necessary in our case because we need a hook point into the device suspend/resume flow to enable the wake-up interrupt as late as possible. Patch #2 adds support for the Broadcom PHY library and driver for Wake-on-LAN proper with the WAKE_UCAST, WAKE_MCAST, WAKE_BCAST, WAKE_MAGIC and WAKE_MAGICSECURE. Note that WAKE_FILTER is supportable, however this will require further discussions and be submitted as a RFC series later on. Patch #3 updates the GENET driver to defer to the PHY for Wake-on-LAN if the PHY supports it, thus allowing the MAC to be powered down to conserve power. Changes in v3: - collected Reviewed-by tags - explicitly use return 0 in bcm54xx_phy_probe() (Paolo) Changes in v2: - introduce PHY_ALWAYS_CALL_SUSPEND and only have the Broadcom PHY driver set this flag to minimize changes to the suspend flow to only drivers that need it - corrected possibly uninitialized variable in bcm54xx_set_wakeup_irq (Simon) ==================== Signed-off-by: David S.
