For MDIO bus The we have:
struct stmmac_mdio_bus_data {
- int bus_id;
int (*phy_reset)(void *priv);
unsigned int phy_mask;
int *irqs;
};
Where:
- o bus_id: bus identifier;
o phy_reset: hook to reset the phy device attached to the bus.
o phy_mask: phy mask passed when register the MDIO bus within the driver.
o irqs: list of IRQs, one per PHY.
with fixed_link support.
static struct stmmac_mdio_bus_data stmmac1_mdio_bus = {
- .bus_id = 1,
- |
- |-> phy device on the bus_id 1
.phy_reset = phy_reset;
|
|-> function to provide the phy_reset on this board
