[net-next,0/6] Microsemi Felix switch support

Message

Claudiu Manoil June 21, 2019, 3:38 p.m. UTC

This device is an ethernet switch core from Microsemi (VSC9959)
integrated as PCIe endpoint into the LS1028a SoC.

Though this switch core has some particularities (i.e. 6 ports,
some register mapping differences), functionally this driver relies
entirely on the Ocelot switch driver providing all the features,
and is basically an instance of the Ocelot core driver.

The first 3 patches are minor refactoring of the common Ocelot code
(core driver).  The rest provide the integration code of the switch
as a PCIe device, the register mapping, corresponding ls1028a DT
nodes (for switch ports link configuration).  There are also few
particularities described by individual patch messages.

Claudiu Manoil (6):
  ocelot: Filter out ocelot SoC specific PCS config from common path
  ocelot: Refactor common ocelot probing code to ocelot_init
  ocelot: Factor out resource ioremap and regmap init common code
  arm64: dts: fsl: ls1028a: Add Felix switch port DT node
  dt-bindings: net: Add DT bindings for Microsemi Felix Switch
  net/mssc/ocelot: Add basic Felix switch driver
