mdiobus_read_nested9
Nested version of the mdiobus_read function
Usage
int mdiobus_read_nested(struct mii_bus * bus, int addr, u32 regnum);
Arguments
bus
the mii_bus struct
addr
the phy address
regnum
register number to read
Overview
In case of nested MDIO bus access avoid lockdep false positives by using mutex_lock_nested.
Note
MUST NOT be called from interrupt context, because the bus read/write functions may wait for an interrupt to conclude the operation.
