[RFC 1/3] mdio-bitbang: add SMI0 mode support

2019-05-08 Thread Michael Grzeschik
Some microchip phys support the Serial Management Interface Protocol (SMI) for the configuration of the extended register set. We add MII_ADDR_SMI0 as an availabe interface to the mdiobb write and read functions, as this interface can be easy realized using the bitbang mdio driver. Signed-off-by:
