s32g SoC family includes 2 serdes subsystems which are made of one PCIe
controller, 2 XPCS and a shared Phy. The Phy got 2 lanes that can be
configured to output PCIe lanes and/or SGMII.
Implement PCIe phy and XPCS support.
Change since v1:
- Fix compile_test
- Use devm_reset_control_get_exclusive()
- Fix s32g_serdes_phy_set_mode_ext()
- Manage devm_clk_bulk_get_all() returns 0
- Fix s32g_serdes_parse_lanes() error management
- Move xpcs filein drivers/net/pcs/
- Add pcs_inband_caps()
- Fix functions in phylink_pcs_ops
- Fix MAINTAINERS
