- qca,sgmii-enable-pll  : For SGMII CPU port, explicitly enable PLL, TX and RX

                          chain along with Signal Detection.

                          This should NOT be enabled for qca8327. If enabled with

                          qca8327 the sgmii port won't correctly init and an err

                          is printed.

                          This can be required for qca8337 switch with revision 2.

                          A warning is displayed when used with revision greater

                          With CPU port set to sgmii and qca8337 it is advised

                          to set this unless a communication problem is observed.



For QCA8K the 'fixed-link' sub-node supports only the following properties:
