Introduce SMP support for MIPS Creator CI20, which is based on Ingenic JZ4780 SoC. Happy Chinese New Year! 周琰杰 (Zhou Yanjie) (6): MIPS: JZ4780: Introduce SMP support. clocksource: Ingenic: Add high resolution timer support for SMP. dt-bindings: MIPS: Document Ingenic SoCs binding. MIPS: Ingenic: Add 'cpus' node for Ingenic SoCs. MIPS: CI20: Modify DTS to support high resolution timer for SMP. MIPS: CI20: Update defconfig to support SMP. .../bindings/mips/ingenic/ingenic,cpu.yaml | 53 ++++ .../bindings/mips/ingenic/ingenic,soc,yaml | 35 +++ arch/mips/boot/dts/ingenic/ci20.dts | 11 +- arch/mips/boot/dts/ingenic/jz4740.dtsi | 14 + arch/mips/boot/dts/ingenic/jz4770.dtsi | 15 +- arch/mips/boot/dts/ingenic/jz4780.dtsi | 23 ++ arch/mips/boot/dts/ingenic/x1000.dtsi | 14 + arch/mips/configs/ci20_defconfig | 2 + arch/mips/include/asm/mach-jz4740/jz4780-smp.h | 91 +++++++ arch/mips/jz4740/Kconfig | 3 + arch/mips/jz4740/Makefile | 5 + arch/mips/jz4740/prom.c | 4 + arch/mips/jz4740/smp-entry.S | 57 ++++ arch/mips/jz4740/smp.c | 286 +++++++++++++++++++++ arch/mips/kernel/idle.c | 14 +- drivers/clk/ingenic/jz4780-cgu.c | 58 ++++- drivers/clocksource/ingenic-timer.c | 201 ++++++++++----- 17 files changed, 811 insertions(+), 75 deletions(-) create mode 100644 Documentation/devicetree/bindings/mips/ingenic/ingenic,cpu.yaml create mode 100644 Documentation/devicetree/bindings/mips/ingenic/ingenic,soc,yaml create mode 100644 arch/mips/include/asm/mach-jz4740/jz4780-smp.h create mode 100644 arch/mips/jz4740/smp-entry.S create mode 100644 arch/mips/jz4740/smp.c -- 2.7.4
