This series adds support for dwmac gigabit ethernet in the T-Head TH1520 RISC-V SoC along with dts patches to enable the ethernet ports on the BeagleV Ahead and the LicheePi 4A. The pinctrl-th1520 driver, pinctrl binding, and related dts patches are in linux-next so there are no longer any prerequisite series that need to be applied first. Changes in v4: - Rebase on next for pinctrl dependency - Add 'net-next' prefix to subject per maintainer-netdev.rst - Add clocks, clock-names, interrupts and interrupt-names to binding - Simplify driver code by switching from regmap to regualar mmio Changes in v3: - Rebase on v6.12-rc1 - Remove thead,rx-internal-delay and thead,tx-internal-delay properties - Remove unneeded call to thead_dwmac_fix_speed() during probe - Fix filename for the yaml file in MAINTAINERS patch - Link: https://lore.kernel.org/linux-riscv/20240930-th1520-dwmac-v3-0-ae3e03c225ab@xxxxxxxxxxxxxxx/ Changes in v2: - Drop the first patch as it is no longer needed due to upstream commit d01e0e98de31 ("dt-bindings: net: dwmac: Validate PBL for all IP-cores") - Rename compatible from "thead,th1520-dwmac" to "thead,th1520-gmac" - Add thead,rx-internal-delay and thead,tx-internal-delay properties and check that it does not exceed the maximum value - Convert from stmmac_dvr_probe() to devm_stmmac_pltfr_probe() and delete the .remove_new hook as it is no longer needed - Handle return value of regmap_write() in case it fails - Add phy reset delay properties to the BeagleV Ahead device tree - Link: https://lore.kernel.org/linux-riscv/20240926-th1520-dwmac-v2-0-f34f28ad1dc9@xxxxxxxxxxxxxxx/ Changes in v1: - remove thead,gmacapb that references syscon for APB registers - add a second memory region to gmac nodes for the APB registers - Link: https://lore.kernel.org/all/20240713-thead-dwmac-v1-0-81f04480cd31@xxxxxxxxxxxxxxx/ --- Emil Renner Berthing (1): riscv: dts: thead: Add TH1520 ethernet nodes Jisheng Zhang (2): dt-bindings: net: Add T-HEAD dwmac support net: stmmac: Add glue layer for T-HEAD TH1520 SoC .../devicetree/bindings/net/snps,dwmac.yaml | 1 + .../devicetree/bindings/net/thead,th1520-gmac.yaml | 115 +++++++++ MAINTAINERS | 2 + arch/riscv/boot/dts/thead/th1520-beaglev-ahead.dts | 91 +++++++ .../boot/dts/thead/th1520-lichee-module-4a.dtsi | 119 +++++++++ arch/riscv/boot/dts/thead/th1520.dtsi | 50 ++++ drivers/net/ethernet/stmicro/stmmac/Kconfig | 10 + drivers/net/ethernet/stmicro/stmmac/Makefile | 1 + drivers/net/ethernet/stmicro/stmmac/dwmac-thead.c | 268 +++++++++++++++++++++ 9 files changed, 657 insertions(+) --- base-commit: f2493655d2d3d5c6958ed996b043c821c23ae8d3 change-id: 20241020-th1520-dwmac-e14cc8f8427b Best regards, -- Drew Fustini <dfustini@xxxxxxxxxxxxxxx>
