The TC9564 SoC connects to a host using the upstream interface of the PCIe switch it implements. The PCIe switch has three downstream ports; two are exposed externally, and one implements an embedded PCIe endpoint. That endpoint has two functions, and each of those has a 10 Gbps capable DesignWare XGMAC interface. This support was originally submitted earlier this year using a PCI driver within the stmmac source directory. This version instead implements a platform driver, "dwmac-tc9564.c". -Alex Alex Elder (1): dt-bindings: net: add support for Toshiba TC9564 Daniel Thompson (4): net: pcs: pcs-xpcs-regmap: support XPCS memory-mapped MDIO bus via regmap net: stmmac: dwxgmac2: Add XGMAC 3.01a support net: stmmac: dwxgmac2: export symbols for XGMAC 3.01a DMA net: stmmac: support the TC9564 SoC .../devicetree/bindings/net/snps,dwmac.yaml | 26 +- .../bindings/net/toshiba,tc9564-xgmac.yaml | 327 ++++++++++ MAINTAINERS | 10 + drivers/net/ethernet/stmicro/stmmac/Kconfig | 11 + drivers/net/ethernet/stmicro/stmmac/Makefile | 1 + .../ethernet/stmicro/stmmac/dwmac-tc9564.c | 590 ++++++++++++++++++ .../net/ethernet/stmicro/stmmac/dwxgmac2.h | 10 + .../ethernet/stmicro/stmmac/dwxgmac2_core.c | 1 + .../ethernet/stmicro/stmmac/dwxgmac2_descs.c | 1 + .../ethernet/stmicro/stmmac/dwxgmac2_dma.c | 70 ++- drivers/net/pcs/Makefile | 3 +- drivers/net/pcs/pcs-xpcs-regmap.c | 169 +++++ include/linux/pcs/pcs-xpcs-regmap.h | 13 + 13 files changed, 1214 insertions(+), 18 deletions(-) create mode 100644 Documentation/devicetree/bindings/net/toshiba,tc9564-xgmac.yaml create mode 100644 drivers/net/ethernet/stmicro/stmmac/dwmac-tc9564.c create mode 100644 drivers/net/pcs/pcs-xpcs-regmap.c create mode 100644 include/linux/pcs/pcs-xpcs-regmap.h base-commit: 2efb7a11f1aa4d2dc285fe2680cca22cb9f72f64 -- 2.53.0
