This patch series adds support for clause 45 peripherals on busses driven by an mdio controller that is only capable of clause 22 frame format messages by indirect bus accesses.
In order to do so we - change the name of the field probe_capabilities to capabilities in struct mii_bus to represent the bus capabilities in general (not only for probing) - add functions mdiobus_*_mmd() and mdiobus_indirect_mmd() to handle indirect bus accesses - let mdiobus_c45_*() functions check the bus capabilities in order to decide whether a real clause 45 bus transfer or indirect access should be performed - use the new functions to simplify existing code a little bit - and finally allow probing for clause 45 peripherals on busses that are not capable of cause 45 frame format
