Patch set is based on Linus master v4.1-rc1. I would be great if these patches could go into 4.1. To keep the amount of dependencies down the PLL1 clock has been hard coded in the lpc18xx.dtsi file. The clock system of LPC18xx is quite advanced for a MCU and requires two clk drivers to work. A patch set with these drivers and update to the dtsi files will be posted separately. Drivers for pinctrl, gpio and reset are already upstream now. Drivers for ethernet, i2c, rtc and emc (external memories) are also coming for LPC18xx. Right now these can found on: https://github.com/manabian/linux-lpc Sucessfuly tested on Embedded Artist LPC4357 Developers Kit. ARM SoC maintainers: How would like to pick this series up? Could you pick up the patches on the mail list or would you prefer a pull request? Changes since v2: - use pr_fmt in time-lpc32xx.c - use request_irq instead of setup_irq in time-lpc32xx.c - remove default on DEBUG_UART_8250 in Kconfig.debug - update defconfig slightly Changes since v1: - use generic soc match strings in board-dt - remove armv7m reset in board-dt (this wasn't working and a proper reset driver is coming) - move dt aliases to board files - add support for Hitex LPC4350 eval board from Ariel D'Alessandro - rename lpc3250-timer to lpc3220-timer to match lpc32xx.dtsi - add ea (and hitex) to vendor-prefixes - rename lpc4357-ea4357 to lpc4357-ea4357-devkit - add lpc32xx_read_sched_clock from Ezequiel Garcia - use named clk in lpc3220 clocksource driver - rebase on 4.1-rc1 Ariel D'Alessandro (1): ARM: dts: Add DT for Hitex LPC4350 Evaluation Board Joachim Eastwood (6): ARM: lpc18xx: add basic support for NXP LPC18xx/43xx SoCs clocksource: add lpc32xx timer driver doc: dt: add documentation for lpc3220-timer ARM: dts: Add base DT for NXP LPC18xx ARM: dts: Add DT for Embedded Artists LPC4357 Developers Kit ARM: lpc18xx: add kernel config .../bindings/timer/nxp,lpc3220-timer.txt | 26 +++ .../devicetree/bindings/vendor-prefixes.txt | 2 + arch/arm/Kconfig | 20 ++ arch/arm/Kconfig.debug | 3 +- arch/arm/Makefile | 1 + arch/arm/boot/dts/Makefile | 3 + arch/arm/boot/dts/lpc18xx.dtsi | 114 +++++++++ arch/arm/boot/dts/lpc4350-hitex-eval.dts | 45 ++++ arch/arm/boot/dts/lpc4350.dtsi | 39 ++++ arch/arm/boot/dts/lpc4357-ea4357-devkit.dts | 41 ++++ arch/arm/boot/dts/lpc4357.dtsi | 39 ++++ arch/arm/configs/lpc18xx_defconfig | 151 ++++++++++++ arch/arm/mach-lpc18xx/Makefile | 1 + arch/arm/mach-lpc18xx/Makefile.boot | 3 + arch/arm/mach-lpc18xx/board-dt.c | 22 ++ drivers/clocksource/Kconfig | 10 + drivers/clocksource/Makefile | 1 + drivers/clocksource/time-lpc32xx.c | 259 +++++++++++++++++++++ 18 files changed, 779 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/timer/nxp,lpc3220-timer.txt create mode 100644 arch/arm/boot/dts/lpc18xx.dtsi create mode 100644 arch/arm/boot/dts/lpc4350-hitex-eval.dts create mode 100644 arch/arm/boot/dts/lpc4350.dtsi create mode 100644 arch/arm/boot/dts/lpc4357-ea4357-devkit.dts create mode 100644 arch/arm/boot/dts/lpc4357.dtsi create mode 100644 arch/arm/configs/lpc18xx_defconfig create mode 100644 arch/arm/mach-lpc18xx/Makefile create mode 100644 arch/arm/mach-lpc18xx/Makefile.boot create mode 100644 arch/arm/mach-lpc18xx/board-dt.c create mode 100644 drivers/clocksource/time-lpc32xx.c -- 1.8.0
