They are found in xDSL and xPON modems, and contain PCM (VoIP), Ethernet, USB, GPIO, I2C, SPI (Flash), UART, and PCIe. The EcoNet MIPS SoCs are divided broadly into two families, the EN751221 family based on the 34Kc, and the EN751627 family based on the 1004Kc. Individual SoCs within a family are very similar, only with different peripherals. This patchset adds basic "boots to a console" support for the EN751221 family and adds SmartFiber XP8421-B, a low cost commercially available board that is useful for testing and development. Note that Airoha (AN7523, AN7581) is similar to EcoNet in terms of peripherals, and for historical reasons Airoha chips are sometimes referred to with the EN75xx prefix. However this is a different platform because Airoha chips are ARM based. This patchset is against mips-next. v2 -> v3 * econet,en751221-timer.yaml -> Improve code style * vendor-prefixes.yaml -> Correct alphabetic order * en751221.dtsi - interrupt-controller code style - serial: Explain reason for clock-frequency = <1843200> * v3->v3 diff provided for reference - https://gist.github.com/cjdelisle/21c9f0cd225f499bdff3c574c7f185f2 * CC: linux-mediatek@lists.infradead.org who may be interested. v1 -> v2 * Codestyle - Apply codestyle from "The tip tree handbook" and recommendations - Remove "_rai" and "_m" symbol suffixes which are not standard * irq-econet-en751221.c - Use cleanup.h _guard() and _free() - Separate irq_domain_ops from irq_chip, eliminating econet_intc struct - Remove irqsave in econet_wreg, irqs are already disabled in mask/unmask - Add explainatory comments - Refactor shadow logic for clarity, e.g. INTC_NO_SHADOW -> NOT_PERCPU - Improve error handling in case of invalid DTS * econet,timer-hpt.yaml - Rename to econet,timer-en751221.yaml - Impose rule: "reg" must have 1 item on EN751221 and 2 on EN751627 * timer-econet-hpt.c - Rename to timer-econet-en751221.c to follow naming scheme from DT * econet,en751221-intc.yaml - Fix validation error from required: interrupt-parent - shadow-interrupts -> switch to uint32-matrix for list of pairs * MAINTAINERS -> Fixed accidental F: MAINTAINERS * Replace "test image" with device SmartFiber-XP8421-B * Restructure arch/mips/econet/Kconfig per arch/mips/ralink example * v1->v2 diff is offered for reference: - https://gist.github.com/cjdelisle/bb3acab78b5f70dcdfe5dd6338293efe Caleb James DeLisle (10): dt-bindings: vendor-prefixes: Add EcoNet dt-bindings: interrupt-controller: Add EcoNet EN751221 INTC irqchip: Add EcoNet EN751221 INTC dt-bindings: timer: Add EcoNet EN751221 "HPT" CPU Timer clocksource/drivers: Add EcoNet Timer HPT driver dt-bindings: mips: Add EcoNet platform binding mips: Add EcoNet MIPS platform support dt-bindings: vendor-prefixes: Add SmartFiber mips: dts: Add EcoNet DTS with EN751221 and SmartFiber XP8421-B board MAINTAINERS: Add entry for newly added EcoNet platform. .../econet,en751221-intc.yaml | 78 +++++ .../devicetree/bindings/mips/econet.yaml | 26 ++ .../bindings/timer/econet,en751221-timer.yaml | 80 +++++ .../devicetree/bindings/vendor-prefixes.yaml | 4 + MAINTAINERS | 12 + arch/mips/Kbuild.platforms | 1 + arch/mips/Kconfig | 25 ++ arch/mips/boot/compressed/uart-16550.c | 5 + arch/mips/boot/dts/Makefile | 1 + arch/mips/boot/dts/econet/Makefile | 2 + arch/mips/boot/dts/econet/en751221.dtsi | 67 ++++ .../econet/en751221_smartfiber_xp8421-b.dts | 19 ++ arch/mips/econet/Kconfig | 48 +++ arch/mips/econet/Makefile | 2 + arch/mips/econet/Platform | 5 + arch/mips/econet/init.c | 78 +++++ drivers/clocksource/Kconfig | 8 + drivers/clocksource/Makefile | 1 + drivers/clocksource/timer-econet-en751221.c | 216 ++++++++++++ drivers/irqchip/Kconfig | 5 + drivers/irqchip/Makefile | 1 + drivers/irqchip/irq-econet-en751221.c | 309 ++++++++++++++++++ 22 files changed, 993 insertions(+) create mode 100644 Documentation/devicetree/bindings/interrupt-controller/econet,en751221-intc.yaml create mode 100644 Documentation/devicetree/bindings/mips/econet.yaml create mode 100644 Documentation/devicetree/bindings/timer/econet,en751221-timer.yaml create mode 100644 arch/mips/boot/dts/econet/Makefile create mode 100644 arch/mips/boot/dts/econet/en751221.dtsi create mode 100644 arch/mips/boot/dts/econet/en751221_smartfiber_xp8421-b.dts create mode 100644 arch/mips/econet/Kconfig create mode 100644 arch/mips/econet/Makefile create mode 100644 arch/mips/econet/Platform create mode 100644 arch/mips/econet/init.c create mode 100644 drivers/clocksource/timer-econet-en751221.c create mode 100644 drivers/irqchip/irq-econet-en751221.c
