Davinci's EMAC device has an in-built MDIO controller and a CPDMA engine.
These hardware modules are not restricted to EMAC device alone. For example,
CPSW3G (3-port gigabit ethernet switch) hardware uses these very same modules
internally. This patch series separates out EMAC's MDIO and CPDMA
functionality, allowing these individual pieces to be reused across TI
hardware.
This patch series has been broadly organized as follows:
MDIO:
- Add new functionality
netdev: separate out davinci mdio controller code
- Hookup new functionality
davinci: add mdio platform devices
netdev: switch davinci emac to new mdio driver
- Cleanup left over cruft
davinci: cleanup unused davinci mdio arch code
netdev: cleanup unused davinci mdio emac code
CPDMA:
- Add new functionality
netdev: separate out davinci cpdma controller code
- Hookup new functionality
netdev: switch davinci emac to new cpdma layer
- Cleanup left over cruft
netdev: cleanup unused davinci emac cpdma code
This series has been tested on dm365 and tnetv107x (with additional cpsw
patches) hardware. Additional omap tree patches will be required for am35xx
as well (not included here).
