[RFC PATCH vN net-next 2/2] net: mscc: ocelot: add support for VSC75XX SPI control

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add support for control for VSC75XX chips over SPI control. Starting with the
VSC9959 code, this will utilize a spi bus instead of PCIe or memory-mapped IO to
control the chip.
