The ENETC PF driver of LS1028A (rev 1.0) is incompatible with the version used on the i.MX95 platform (rev 4.1), except for the station interface (SI) part. To reduce code redundancy and prepare for a new driver for rev 4.1 and later, extract shared interfaces from enetc_pf.c and move them to enetc_pf_common.c. This refactoring lays the groundwork for compiling enetc_pf_common.c into a shared driver for both platforms' PF drivers. Signed-off-by: Wei Fang <wei.fang@nxp.com> --- v6: 1. add enetc_pf_common.h and put the prototypes of functions exported by enetc_pf_common.c into enetc_pf_common.h 2. add linux/of.h to enetc_pf.c due to undeclared function 'of_device_is_available' --- drivers/net/ethernet/freescale/enetc/Makefile | 2 +- .../net/ethernet/freescale/enetc/enetc_pf.c | 300 +----------------- .../freescale/enetc/enetc_pf_common.c | 295 +++++++++++++++++ .../freescale/enetc/enetc_pf_common.h | 17 + 4 files changed, 319 insertions(+), 295 deletions(-) create mode 100644 drivers/net/ethernet/freescale/enetc/enetc_pf_common.c create mode 100644 drivers/net/ethernet/freescale/enetc/enetc_pf_common.h
