To: andrew; +Cc: f.fainelli, netdev, davem, kernel
We add support for the KXZ88X3 three port switches using the Microchip
SMI Interface. They are currently only supported using the MDIO-Bitbang
Interface. Which is making use of the mdio_ll_read/write functions. The
patch uses the common functions from the ksz8795 driver.
Signed-off-by: Michael Grzeschik <m.grzeschik@pengutronix.de>
---
RFC -> v1: - added Microchip SMI to description
- added select MDIO_BITBANG
- added return error code handling in mdiobus_read/write
- fixed the stp state handling
- moved tag handling code to seperate patch
v1 -> v2: - completely reworked the driver to use existing ksz8795 functions
