One of the blocking area where fec_mxc is unlikely to move dm can be CLK support, this series trying to add support for it and concentrated on ENET clocking for i.MX6QDL and i.MX6UL.
I've verified this on i.MX6QDL, but the reason for sending this is an 'RFC' is there are some quite few issues with existing fec_mxc driver regarding mdio handling. The dm vs non-dm code in fec_mxc looks very uncomfortable to read and add new support, so I would like create one separate dm driver to make dm related changes if all agree?
know issues: - CLK driver still using enable_fec_anatop_clock function to set the clock, but if we handling this in CLK we need anatop via OF_LIVE. will try this next version - fec_mxc is passing input ref clock, ENET_50MHZ. don't know how to make this dynamic, or this based on MII or any other feature, need help. - ipu_common has legacy clk support, since may boards are using ipu_common better to handle this via CLK so-that move to CLK become easy and meaningful.
