The MAC IP allows to automatically perform PHY auto-negotiatio= n without software interaction. However, this feature (a) fundamentally clashes with the way libphy wor= ks and (b) is unable to deal with quirky PHYs that require special treatme= nt. In this series, pxa168_eth driver is rewritten to completely disable th= at feature and properly deal with libphy provided PHYs. The other two driv= ers are suspect to future patch sets, also removing the code related with i= t. Currently, the patches are based on next-20141009 and will be resent on= ce 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 o= n 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", t= oo. 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-dr= iver 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=3Ddhcp on 100M FD.
