The MAC IP allows to automatically perform PHY auto-negotiation without software interaction. However, this feature (a) fundamentally clashes with the way libphy works and (b) is unable to deal with quirky PHYs that require special treatment. In this series, pxa168_eth driver is rewritten to completely disable that feature and properly deal with libphy provided PHYs. The other two drivers are suspect to future patch sets, also removing the code related with it. Currently, the patches are based on next-20141009 and will be resent once v3.18-rc1 drops. This is a Request-For-Test on both BG2Q and MMP/gplug as these are the current users of pxa168_eth. A branch with this patches on top of next-20141009 can be found at git://git.infradead.org/users/hesselba/linux-berlin.git devel/bg2-bg2cd-eth-v1 It would be great to get a Tested-byfrom MMP guys on gplug - if they have that board somewhere. Also, BG2Q (Antoine) needs a phy-connection-type property. My guess is that, if it is using internal PHY, it is "mii", too. Patch 1 adds support for Marvell 88E3016 FastEthernet PHY that is also integrated in Marvell Berlin BG2/BG2CD SoCs. Patch 2 allows to pass phy_interface_t on pxa168_eth platform_data that is only used by mach-mmp/gplug. From the board setup, I guessed gplug's PHY is connected via RMII. The patch isn't even compile tested, so here I need a Tested-by from MMP guys. Patches 3-5 prepare proper libphy handling and finally remove all in-driver PHY mangling related to the feature explained above. Patches 6-8 add corresponding ethernet DT nodes to BG2, BG2CD, and BG2-based Sony NSZ-GS7. I have tested all this on GS7 successfully with ip=dhcp on 100M FD.
