2019-06-27net: dsa: microchip: Dispose of ksz_io_opsMarek Vasut
Since the driver now uses regmap , get rid of ad-hoc ksz_io_ops abstraction, which no longer has any meaning. Moreover, since regmap has it's own locking, get rid of the register access mutex.

2019-06-27net: dsa: microchip: Initial SPI regmap supportMarek Vasut
Add basic SPI regmap support into the driver. Previous patches unconver that ksz_spi_write() is always ever called with len = 1, 2 or 4. We can thus drop the if (len > SPI_TX_BUF_LEN) check and we can also drop the allocation of the txbuf which is part of the driver data and wastes 256 bytes for no reason. Regmap covers the whole thing now.

2019-06-14net: dsa: microchip: Support optional 125MHz SYNCLKO outputRobert Hancock
The KSZ9477 series chips have a SYNCLKO pin which by default outputs a 25MHz clock, but some board setups require a 125MHz clock instead. Added a microchip,synclko-125 device tree property to allow indicating a 125MHz clock output is required. Signed-off-by: Robert Hancock <hancock@sedsystems.ca> Signed-off-by: David S.

2019-06-14net: dsa: microchip: Add PHY errata workaroundsRobert Hancock
The Silicon Errata and Data Sheet Clarification documents for the KSZ9477 series of chips describe a number of otherwise undocumented PHY register settings which are required to work around various chip errata.

2019-02-24net: dsa: microchip: add MIB counter reading supportTristram Ha
Add background MIB counter reading support. Port MIB counters should only be read when there is link. Otherwise it is a waste of time as hardware never increases those counters. There are exceptions as some switches keep track of dropped counts no matter what.

Prepare PHY for proper advertisement as sometimes the PHY in the switch has its own problems even though it may share the PHY id from regular PHY but the fixes in the PHY driver do not apply.

2017-05-31dsa: add DSA switch driver for Microchip KSZ9477Woojung Huh
The KSZ9477 is a fully integrated layer 2, managed, 7 ports GigE switch with numerous advanced features. 5 ports incorporate 10/100/1000 Mbps PHYs. The other 2 ports have interfaces that can be configured as SGMII, RGMII, MII or RMII. Either of these may connect directly to a host processor or to an external PHY. The SGMII port may interface to a fiber optic transceiver. This driver currently supports vlan, fdb, mdb & mirror dsa switch operations.
