+Subject: [PATCH] staging: fsl_ppfe/eth: reorganize platform phy parameters
+
+- Use "phy-handle" and of_* functions to get phy node and fixed-link
+parameters
+
+- Reorganize phy parameters and initialize them only if phy-handle
+or fixed-link is defined in the dtb.
+
+- correct typo pfe_get_gemac_if_proprties to pfe_get_gemac_if_properties
