    1 * APM X-Gene 15Gbps Multi-purpose PHY nodes
    2 
    3 PHY nodes are defined to describe on-chip 15Gbps Multi-purpose PHY. Each
    4 PHY (pair of lanes) has its own node.
    5 
    6 Required properties:
    7 - compatible            : Shall be "apm,xgene-phy".
    8 - reg                   : PHY memory resource is the SDS PHY access resource.
    9 - #phy-cells            : Shall be 1 as it expects one argument for setting
   10                           the mode of the PHY. Possible values are 0 (SATA),
   11                           1 (SGMII), 2 (PCIe), 3 (USB), and 4 (XFI).
   12

   14 - status                : Shall be "ok" if enabled or "disabled" if disabled.

   23                           data earlier than the nominal sampling point. 1 means
   24                           sample data later than the nominal sampling point.
   25                           Two set of 3-tuple setting for each (up to 3)
   26                           supported link speed on the host. Default is 0.
   27 - apm,tx-boost-gain     : Frequency boost AC (LSB 3-bit) and DC (2-bit)
   28                           gain control. Two set of 3-tuple setting for each
   29                           (up to 3) supported link speed on the host. Range is
   30                           between 0 to 31 in unit of dB. Default is 3.

   33                           Range is between 0 to 199500 in unit of uV.
   34                           Default is 199500 uV.
   35 - apm,tx-pre-cursor1    : 1st pre-cursor emphasis taps control. Two set of
   36                           3-tuple setting for each (up to 3) supported link
   37                           speed on the host. Range is 0 to 273000 in unit of
   38                           uV. Default is 0.

   41                           speed on the host. Range is 0 to 127400 in unit uV.
   42                           Default is 0x0.
   43 - apm,tx-post-cursor    : Post-cursor emphasis taps control. Two set of
