For instance, to change where the PHY's clock input is, + or to add a delay to account for latency issues in the data path. In order + to support such contingencies, the PHY Layer allows platform code to register + fixups to be run when the PHY is brought up (or subsequently reset). + + When the PHY Layer brings up a PHY it checks to see if there are any fixups + registered for it, matching based on UID (contained in the PHY device's phy_id + field) and the bus identifier (contained in phydev->dev.bus_id). Both must + match, however two constants, PHY_ANY_ID and PHY_ANY_UID, are provided as + wildcards for the bus ID and UID, respectively. + + When a match is found, the PHY layer will invoke the run function associated + with the fixup. This function is passed a pointer to the phy_device of + interest. It should therefore only operate on that PHY. + + The platform code can either register the fixup using phy_register_fixup(): + + int phy_register_fixup(const char *phy_id, + u32 phy_uid, u32 phy_uid_mask, + int (*run)(struct phy_device *)); + + Or using one of the two stubs, phy_register_fixup_for_uid() and + phy_register_fixup_for_id(): + + int phy_register_fixup_for_uid(u32 phy_uid, u32 phy_uid_mask, + int (*run)(struct phy_device *)); + int phy_register_fixup_for_id(const char *phy_id, + int (*run)(struct phy_device *)); + + The stubs set one of the two matching criteria, and set the other one to + match anything. + diff --git a/drivers/net/arm/at91_ether.c b/drivers/net/arm/at91_ether.c index 978e20a1791b..1e39e78f1778 100644 --- a/drivers/net/arm/at91_ether.c +++ b/drivers/net/arm/at91_ether.c @@ -1248,3 +1248,4 @@ module_exit(at91ether_exit) MODULE_LICENSE("GPL"); MODULE_DESCRIPTION("AT91RM9200 EMAC Ethernet driver"); MODULE_AUTHOR("Andrew Victor"); +MODULE_ALIAS("platform:" DRV_NAME); diff --git a/drivers/net/arm/ep93xx_eth.c b/drivers/net/arm/ep93xx_eth.c index 91a6590d107b..ecd8fc6146e9 100644 --- a/drivers/net/arm/ep93xx_eth.c +++ b/drivers/net/arm/ep93xx_eth.c @@ -897,6 +897,7 @@ static struct platform_driver ep93xx_eth_driver = { .remove = ep93xx_eth_remove, .driver = { .name = "ep93xx-eth", + .owner = THIS_MODULE, }, }; @@ -914,3 +915,4 @@ static void __exit ep93xx_eth_cleanup_module(void) module_init(ep93xx_eth_init_module); module_exit(ep93xx_eth_cleanup_module); MODULE_LICENSE("GPL"); +MODULE_ALIAS("platform:ep93xx-eth"); diff --git a/drivers/net/atlx/atl1.c b/drivers/net/atlx/atl1.c index 5586fc624688..0afe522b8f7b 100644 --- a/drivers/net/atlx/atl1.c +++ b/drivers/net/atlx/atl1.c @@ -91,6 +91,144 @@ #include "atlx.c" /* + * This is the only thing that needs to be changed to adjust the + * maximum number of ports that the driver can manage. + */ +#define ATL1_MAX_NIC 4 + +#define OPTION_UNSET -1 +#define OPTION_DISABLED 0 +#define OPTION_ENABLED 1 + +#define ATL1_PARAM_INIT { [0 ...
