The Octeon SOC has two types of Ethernet ports, each type with its own
driver. However, the PHYs for all the ports are controlled by a
common MDIO bus. Because the mdio driver is not associated with a
particular driver, but is instead a system level resource, we create s
stand-alone driver for it.
As for the driver, we put the register definitions in
arch/mips/include/asm/octeon where most of the other Octeon register
definitions live. This is a platform driver with the platform device
for "mdio-octeon" being registered in the platform startup code.

5 siblings, 1 reply; 14+ messages in thread
From: David Daney @ 2009-10-14 19:04 UTC (permalink / raw)
To: ralf, linux-mips, netdev; +Cc: David Daney
The Octeon MGMT Ethernet ports are present in some members of the
Octeon SOC family (cn52XX and cn56XX have them).
The mdio bus connected to the MGMT PHYs is shared with the main
octeon-ethernet driver, we force it to be loaded first by calling
octeon_mdiobus_force_mod_depencency. The platform devices for the
MGMT Ethernet ports are added in
arch/mips/cavium-octeon/octeon-platform.c, and the register
definitions for the ports live in arch/mips/include/asm/octeon/ along
with their ilk.
Although it currently is the only driver in drivers/net/octeon, the
directory was created looking forward to the day that octeon-ethernet
will move there from its current home in drivers/staging.

The octeon-ethernet driver shares an mdio bus with the octeon-mgmt
driver. Here we convert the octeon-ethernet driver to use the PHY
Abstraction Layer.

* [PATCH 5/6] netdev: Add Ethernet driver for Octeon MGMT devices.
2009-10-07 23:07 [PATCH 0/6] netdev: Octeon MGMT new driver + octeon_ethernet updates David Daney

From: David Daney @ 2009-10-07 23:10 UTC (permalink / raw)
To: ralf, linux-mips, netdev; +Cc: David Daney
The Octeon MGMT Ethernet ports are present in some members of the
Octeon SOC family (cn52XX and cn56XX have them).
The mdio bus connected to the MGMT PHYs is shared with the main
octeon-ethernet driver, we force it to be loaded first by calling
octeon_mdiobus_force_mod_depencency. The platform devices for the
MGMT Ethernet ports are added in
arch/mips/cavium-octeon/octeon-platform.c, and the register
definitions for the ports live in arch/mips/include/asm/octeon/ along
with their ilk.
Although it currently is the only driver in drivers/net/octeon, the
directory was created looking forward to the day that octeon-ethernet
will move there from its current home in drivers/staging.
