[RFC PATCH v3 net-next 00/10] add support for VSC75XX control over SPI

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

 



Add support for configuration and control of the VSC7511, VSC7512, VSC7513, and
VSC7514 chips over a SPI interface. The intent is to control these chips from an
external CPU. The expectation is to have most of the features of the
net/ethernet/mscc/ocelot_vsc7514 driver.

RFC history:
v1 (accidentally named vN)
	Initial architecture. Not functional
	General concepts laid out

v2
	Near functional. No CPU port communication, but control over all
	external ports
	Cleaned up regmap implementation from v1

v3
	Functional
	Shared MDIO transactions routed through mdio-mscc-miim
	CPU / NPI port enabled by way of vsc7512_enable_npi_port /
	felix->info->enable_npi_port
	NPI port tagging functional - Requires a CPU port driver that supports
	frames of 1520 bytes. Verified with a patch to the cpsw driver
