The ethernet controller of SG2044 is Synopsys DesignWare IP with custom clock. Add glue layer for it. Since v2, these patch depends on that following patch that provides helper function to compute rgmii clock, and this patch are marked as RFC: https://lore.kernel.org/netdev/20241028-upstream_s32cc_gmac-v4-4-03618f10e3e2@xxxxxxxxxxx/ Changed from v2: - https://lore.kernel.org/netdev/20241025011000.244350-1-inochiama@xxxxxxxxx/ 1. patch 1: merge the first and the second bindings patch to show the all compatible change. 2. patch 2: use of_device_compatible_match helper function to perform check. 2. patch 3: remove unused include and sort the left. 3. patch 3: fix wrong variable usage in sophgo_dwmac_fix_mac_speed 4. patch 3: drop unused variable in the patch. Changed from v1: - https://lore.kernel.org/netdev/20241021103617.653386-1-inochiama@xxxxxxxxx/ 1. patch 2: remove sophgo,syscon as this mac delay is resolved. 2. patch 2: apply all the properties unconditionally. 3. patch 4: remove sophgo,syscon code as this mac delay is resolved. 4. patch 4: use the helper function to compute rgmii clock. 5. patch 4: use remove instead of remove_new for the platform driver.
