From what I can tell with the board schematic in hand, as well as the code delivered, the main changes needed are: 1. A new address space layout for /dwmac5/EMAC3 MTL/DMA regs 2. A new programming sequence required for the EMAC3 base platforms This series makes those adaptations as well as other housekeeping items such as converting dt-bindings to yaml, adding clock descriptions, etc. [0] https://git.codelinaro.org/clo/la/kernel/ark-5.14/-/commit/510235ad02d7f0df478146fb00d7a4ba74821b17 Thanks, Andrew Bhupesh Sharma (3): dt-bindings: net: snps,dwmac: Update interrupt-names dt-bindings: net: snps,dwmac: Add Qualcomm Ethernet ETHQOS compatibles dt-bindings: net: qcom,ethqos: Convert bindings to yaml Brian Masney (1): net: stmmac: Add EMAC3 variant of dwmac4 .../devicetree/bindings/net/qcom,ethqos.txt | 66 ---- .../devicetree/bindings/net/qcom,ethqos.yaml | 113 ++++++ .../devicetree/bindings/net/snps,dwmac.yaml | 11 +- MAINTAINERS | 2 +- arch/arm64/boot/dts/qcom/sa8540p-ride.dts | 181 ++++++++++ arch/arm64/boot/dts/qcom/sc8280xp.dtsi | 53 +++ drivers/clk/qcom/gcc-sc8280xp.c | 18 + .../stmicro/stmmac/dwmac-qcom-ethqos.c | 161 ++++++--- drivers/net/ethernet/stmicro/stmmac/dwmac4.h | 32 +- .../net/ethernet/stmicro/stmmac/dwmac4_core.c | 190 ++++++++-- .../net/ethernet/stmicro/stmmac/dwmac4_dma.c | 336 ++++++++++++++---- .../net/ethernet/stmicro/stmmac/dwmac4_dma.h | 38 ++ .../net/ethernet/stmicro/stmmac/dwmac4_lib.c | 144 ++++++-- drivers/net/ethernet/stmicro/stmmac/hwif.c | 29 +- drivers/net/ethernet/stmicro/stmmac/hwif.h | 2 + .../ethernet/stmicro/stmmac/stmmac_ethtool.c | 6 +- .../net/ethernet/stmicro/stmmac/stmmac_main.c | 17 +- .../net/ethernet/stmicro/stmmac/stmmac_mdio.c | 9 +- .../net/ethernet/stmicro/stmmac/stmmac_ptp.c | 4 +- include/dt-bindings/clock/qcom,gcc-sc8280xp.h | 2 + include/linux/stmmac.h | 1 + 21 files changed, 1164 insertions(+), 251 deletions(-) delete mode 100644 Documentation/devicetree/bindings/net/qcom,ethqos.txt create mode 100644 Documentation/devicetree/bindings/net/qcom,ethqos.yaml
