The 98DX3236, 98DX3336 and 98DX4251 are a set of switch ASICs with integrated CPUs. They CPU block is common within these product lines and (as far as I can tell/have been told) is based on the Armada XP. There are a few differences due to the fact they have to squeeze the CPU into the same package as the switch. I've rebased this series against linux-pinctrl/devel to get access to mvebu_mmio_mpp_ctrl. Everything else still applies cleanly to v4.10.0-rc5. Chris Packham (4): clk: mvebu: support for 98DX3236 SoC Changes in v2: - Update devicetree binding documentation for new compatible string Changes in v3: - Add 98dx3236 support to mvebu/clk-corediv.c rather than creating a new driver. - Document mv98dx3236-corediv-clock binding Changes in v4: - None Changes in v5: - Collect ack from Rob - Remove explicit initialisation of fields to 0 in mv98dx3236_coreclks - Register dummy clock provider for marvell,mv98dx3236-cpu-clock Changes in v6: - None. Note this has already been applied to clk-net, I've just included it for completeness. arm: mvebu: support for SMP on 98DX3336 SoC Changes in v2: - Document new enable-method value - Correct some references from 98DX4521 to 98DX3236 Changes in v3: - Simplify mv98dx3236_resume_init by using of_io_request_and_map() Changes in v4: - integrate changes into platsmp.c instead of new init call - avoid duplicated code. - fix error return - Collect ack from Rob Changes in v5: - Remove useless casts (thanks to Stephen Boyd) Changes in v6: - use a #define instead of a new structure for resume control registers. arm: mvebu: Add device tree for 98DX3236 SoCs Changes in v2: - Update devicetree binding documentation to reflect that 98DX3336 and 984251 are supersets of 98DX3236. - disable crypto block - disable sdio for 98DX3236, enable for 98DX4251 Changes in v3: - fix typo 4521 -> 4251 - document prestera bindings - rework corediv-clock binding - add label to packet processor node - add new compatible string for DFX server Changes in v4: - Collect ack from Rob Changes in v5: - Fixup license text. Add labels to nodes. Changes in v6: - None arm: mvebu: Add device tree for db-dxbc2 and db-xc3-24g4xg boards Changes in v5: - update license text - use node labels Changes in v6: - Rename dts files to include 'armada-xp-' prefix Kalyan Kinthada (1): pinctrl: mvebu: pinctrl driver for 98DX3236 SoC Changes in v2: - include sdio support for the 98DX4251 Changes in v3: - None Changes in v4: - Correct some discrepencies between binding and driver. - Collect acks from Rob and Sebastian Changes in v5: - Update bindings to reflect "gpo" pins - Use mvebu_mmio_mpp_ctrl instead of armada_xp_mpp_ctrl (note this is reliant on changes queued in linux-pinctrl) Changes in v6: - None Documentation/devicetree/bindings/arm/cpus.txt | 1 + .../bindings/arm/marvell/98dx3236-resume-ctrl.txt | 16 ++ .../devicetree/bindings/arm/marvell/98dx3236.txt | 23 ++ .../bindings/clock/mvebu-corediv-clock.txt | 1 + .../devicetree/bindings/clock/mvebu-cpu-clock.txt | 1 + .../devicetree/bindings/net/marvell,prestera.txt | 50 ++++ .../pinctrl/marvell,armada-98dx3236-pinctrl.txt | 46 ++++ arch/arm/boot/dts/armada-xp-98dx3236.dtsi | 254 +++++++++++++++++++++ arch/arm/boot/dts/armada-xp-98dx3336.dtsi | 76 ++++++ arch/arm/boot/dts/armada-xp-98dx4251.dtsi | 90 ++++++++ arch/arm/boot/dts/armada-xp-db-dxbc2.dts | 151 ++++++++++++ arch/arm/boot/dts/armada-xp-db-xc3-24g4xg.dts | 142 ++++++++++++ arch/arm/mach-mvebu/platsmp.c | 75 ++++++ drivers/clk/mvebu/armada-xp.c | 39 ++++ drivers/clk/mvebu/clk-corediv.c | 23 ++ drivers/clk/mvebu/clk-cpu.c | 8 + drivers/pinctrl/mvebu/pinctrl-armada-xp.c | 156 +++++++++++++ 17 files changed, 1152 insertions(+) create mode 100644 Documentation/devicetree/bindings/arm/marvell/98dx3236-resume-ctrl.txt create mode 100644 Documentation/devicetree/bindings/arm/marvell/98dx3236.txt create mode 100644 Documentation/devicetree/bindings/net/marvell,prestera.txt create mode 100644 Documentation/devicetree/bindings/pinctrl/marvell,armada-98dx3236-pinctrl.txt create mode 100644 arch/arm/boot/dts/armada-xp-98dx3236.dtsi create mode 100644 arch/arm/boot/dts/armada-xp-98dx3336.dtsi create mode 100644 arch/arm/boot/dts/armada-xp-98dx4251.dtsi create mode 100644 arch/arm/boot/dts/armada-xp-db-dxbc2.dts create mode 100644 arch/arm/boot/dts/armada-xp-db-xc3-24g4xg.dts inter-diff to v5: + iounmap(base); return 0; }
