4 Subject: [PATCH] staging: fsl_ppfe/eth: reorganize platform phy parameters
5
6 - Use "phy-handle" and of_* functions to get phy node and fixed-link
7 parameters
8
9 - Reorganize phy parameters and initialize them only if phy-handle
10 or fixed-link is defined in the dtb.
11
12 - correct typo pfe_get_gemac_if_proprties to pfe_get_gemac_if_properties
13
