    ARM: dts: Add support for dra72-evm rev C (SR2.0) · a4240d3a
    Nishanth Menon authored
    DRA72-EVM now has an upgrade to Rev C with SR2.0 silicon. As part of
    this change, a few updates were factored in that were software
    incompatible with previous board in few areas:
    - We now use DP83867 ethernet phy instead of older DP838865 which fails
      in certain use cases.
    - Two Ethernet ports now instead of the single one in rev B.
    - polarities changed for certain pcf gpios
    - Due to SoC phy current requirements, VDDA supplies are split between
     ldo3 and ldo2 (ldo2 was previously unused). NOTE: DSS (VDDA_VIDEO) is
     still supplied by ldo5, HDMI is now supplied by LDO2 instead of using
     LDO3.
    
    NOTE: It does not make much sense to spin off a new board compatible
    flag since there is no real benefit for the same.
