Subject: [PATCH 2/9] davinci: specify phy_id rather than auto-detect
The cpdma/mdio refactoring incorrectly defaulted to using the first phy
detected on the platform. Although auto detection works on most sane
platforms, it can prove to be problematic on some.
For example, the da830/omap-l137 evm has an on-board switch that always
connects 100/full. Consequently, normal phy auto-detection does not work
on this platform.
Rather than risk breaking other boards, this patch reverts to using hard-coded
phy ids on platforms that did so earlier.
