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
omap: add mdio platform devices
netdev: switch davinci emac to new mdio driver
- Cleanup left over cruft
davinci: cleanup unused davinci mdio arch code
omap: 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. Although am3517 (omap) board support code has been updated
as needed, emac does not work on this platform.
Changes from v1:
1. Fixed memory leak in cpdma_chan_create() failure case
2. Included new omap patches for am3517, avoids build breakage
Changes from v2:
1. Updated series to include mityomapl138 board
2. Minor white-space fixes
Changes from v3 (rolled in "post cpdma/mdio refactoring fixes" series):
1. allow forced 100/full mode instead of phy auto-detect
2. specify phy_id on boards that had a phy_mask defined earlier
3. requeue cpdma descriptors when EOQ at submit
4. use calculated mdio bus access times instead of hardcoded delays
5. work around emac soft-reset impact on mdio controller state
6. extend register dumps to include cpdma registers
7. updated sign offs and acks
