This builds on the Airoha EN7523 clock driver and the Mediatek PCIe driver. Patch 6 is upstreaming of Ahmed Naseef's work on EcoNet PCIe, which was developed to support the EN7528, but which works equally on the EN751221. There is also a workaround in patch 7 to gracefully handle PCI hardware which does not advertize a bridge window and instead always reads zero. Changes in v2: * clock/econet,en751221-scu.h drop EN751221_MAX_CLKS * clk-en7523.c add EN751221_MAX_CLKS * econet,en751221-chip-scu.yaml drop in favor of using mtd/syscon.yaml * airoha,en7523-scu.yaml drop redundant example * econet,en751221-pcie-phy.yaml Refer to PHYs as "gen1" and "gen2" * pcie-mediatek.c Exclude pcie_retrain_link() when building as a module * en751221.dtsi "econet,en751221-scu" is not a "syscon" * Rebase to linux-next * v1: https://lore.kernel.org/linux-mips/20260303190948.694783-1-cjd@cjdns.fr/ Caleb James DeLisle (8): dt-bindings: clock, reset: Add econet EN751221 clk: airoha: Add econet EN751221 clock/reset support to en7523-scu dt-bindings: phy: Document PCIe PHY in EcoNet EN751221 and EN7528 phy: econet: Add PCIe PHY driver for EcoNet EN751221 and EN7528 SoCs. dt-bindings: PCI: mediatek: Add support for EcoNet EN7528 PCI: mediatek: Add support for EcoNet EN7528 SoC PCI: Skip bridge window reads when window is not supported mips: dts: Add PCIe to EcoNet EN751221 .../bindings/clock/airoha,en7523-scu.yaml | 7 +- .../devicetree/bindings/mfd/syscon.yaml | 2 + .../bindings/pci/mediatek-pcie.yaml | 1 + .../phy/econet,en751221-pcie-phy.yaml | 50 ++++ MAINTAINERS | 9 + arch/mips/boot/dts/econet/en751221.dtsi | 114 +++++++++ .../econet/en751221_smartfiber_xp8421-b.dts | 21 ++ arch/mips/econet/Kconfig | 2 + drivers/clk/Kconfig | 6 +- drivers/clk/clk-en7523.c | 238 +++++++++++++++++- drivers/pci/controller/Kconfig | 2 +- drivers/pci/controller/pcie-mediatek.c | 118 +++++++++ drivers/pci/probe.c | 6 + drivers/phy/Kconfig | 12 + drivers/phy/Makefile | 1 + drivers/phy/phy-econet-pcie.c | 180 +++++++++++++ .../dt-bindings/clock/econet,en751221-scu.h | 13 + .../dt-bindings/reset/econet,en751221-scu.h | 49 ++++ 18 files changed, 821 insertions(+), 10 deletions(-) create mode 100644 Documentation/devicetree/bindings/phy/econet,en751221-pcie-phy.yaml create mode 100644 drivers/phy/phy-econet-pcie.c create mode 100644 include/dt-bindings/clock/econet,en751221-scu.h create mode 100644 include/dt-bindings/reset/econet,en751221-scu.h base-commit: 3fa5e5702a82d259897bd7e209469bc06368bf31 -- 2.39.5
