Micrel has some drivers on their web site to support some chips. For that chips they do virtual mdio over spi. And driver is available on download page: http://www.microchip.com/wwwproducts/en/KSZ8895 Documentation->Software library. Both driver and DSA driver. Driver has to work with some minor fixups related to your kernel version. But I think they are don't care about up-streaming that code. So you can take their code as a reference. 2017-08-28 17:09 GMT+03:00 Andrew Lunn <andrew@lunn.ch>: >> I may be confused here, but AFAICT: >> >> 1) Yes, it has standard layout when accessed over MDIO. > > > Section 4.8 of the datasheet says: > > All the registers defined in this section can be also accessed > via the SPI interface. > > Meaning all PHY registers can be access via the SPI interface.
