[PATCH net-next 6/6] net/mssc/ocelot: Add basic Felix switch driver
From: Claudiu Manoil
Date: Fri Jun 21 2019 - 11:39:07 EST
This supports a switch core ethernet device from Microsemi
(VSC9959) that can be integrated on different SoCs as a PCIe
endpoint device.
The switchdev functionality is provided by the core Ocelot
switch driver. In this regard, the current driver is an
instance of Microsemi's Ocelot core driver.
The patch adds the PCI device driver part and defines the
register map for the Felix switch core, as it has some
differences in register addresses and bitfield mappings
compared to the Ocelot switch. Also some registers or
bitfields present on Ocelot are not available on Felix.
That's why this driver has its own register map instance.
Other than that, the common registers and bitfields have the
same functionality and share the same name.
In a few cases, some h/w operations have to be done differently
on Felix due to missing bitfields. This is the case for the
switch core reset and init. Because for this operation Ocelot
uses some bits that are not present on Felix, the later has to
use a register from the global registers block (GCB) instead.
