This sixth round adds minor fixes to USART driver, and adds some Acks. STM32 MCUs are Cortex-M CPU, used in various applications (consumer electronics, industrial applications, hobbyists...). Datasheets, user and programming manuals are publicly available on STMicroelectronics website. With this series applied, the STM32F419 Discovery can boot succesfully. Changes since v5: ----------------- - Change st,hw-flow-ctrl property to auto-flow-control (Rob) - Constify stm32_uart_ops (Joe) - Propagate request_irq error in USART driver (Andy) - Applies Acked-by and Reviewed-by (Rob, Peter) Changes since v4: ----------------- - Cosmetic changes in USART driver (Andy) - Apply Acks on reset driver & bindings (Philipp & Rob) Changes since v3: ----------------- - Fix and simplify error path in ARMv7-M Systick driver (Daniel) - Improve reset bindings documentation (Philipp) - Fix trailing lines anf typos in reset driver & doc (Philipp & Chanwoo) - Fix MODULE_LICENCE in USART driver (Paul) - Refactor USART baudrate calculation (Peter & Andy) - Fix error path in USART init (Peter & Russell) - Fix HW flow control in USART driver (Peter) - Fix serial port type number to unused one (Peter) - Applies Chanwoo's Tested-by on the series Changes since v2: ----------------- - Remove pinctrl driver from the series. - Remove reset_controller_of_init(), and reset the timers in the bootloader - Add HW flow contrl property for serial driver - Lots of changes in the DTS file, as per Andreas recommendations - Some Kconfig clean-ups - Adapt the config to be compatible with Andreas' bootwrapper, except UART port. - Various fixes in documentation Changes since v1: ----------------- - Move bindings documentation in their own patches (Andreas) - Rename ARM System timer to armv7m-systick (Rob) - Add clock-frequency property handling in armv7m-systick (Rob) - Re-factor the reset controllers into a single controller (Philipp) - Add kerneldoc to reset_controller_of_init (Philipp) - Add named constants in include/dt-bindings/reset/ (Philipp) - Make pinctrl driver to depend on ARCH_STM32 or COMPILE_TEST (Geert) - Introduce CPUV7M_NUM_IRQ config flag to indicate the number of interrupts supported by the MCU, in order to limit memory waste in vectors' table (Uwe) Maxime Coquelin (15): scripts: link-vmlinux: Don't pass page offset to kallsyms if XIP Kernel ARM: ARMv7-M: Enlarge vector table up to 256 entries dt-bindings: Document the ARM System timer bindings clocksource/drivers: Add ARM System timer driver dt-bindings: Document the STM32 reset bindings drivers: reset: Add STM32 reset driver dt-bindings: Document the STM32 timer bindings clockevents/drivers: Add STM32 Timer driver dt-bindings: Document the STM32 USART bindings serial: stm32-usart: Add STM32 USART Driver ARM: Add STM32 family machine ARM: dts: Add ARM System timer as clockevent in armv7m ARM: dts: Introduce STM32F429 MCU ARM: configs: Add STM32 defconfig MAINTAINERS: Add entry for STM32 MCUs Documentation/arm/stm32/overview.txt | 32 + Documentation/arm/stm32/stm32f429-overview.txt | 22 + .../devicetree/bindings/arm/armv7m_systick.txt | 26 + .../devicetree/bindings/reset/st,stm32-rcc.txt | 107 +++ .../devicetree/bindings/serial/st,stm32-usart.txt | 32 + .../devicetree/bindings/timer/st,stm32-timer.txt | 22 + MAINTAINERS | 8 + arch/arm/Kconfig | 18 + arch/arm/Makefile | 1 + arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/armv7-m.dtsi | 6 + arch/arm/boot/dts/stm32f429-disco.dts | 71 ++ arch/arm/boot/dts/stm32f429.dtsi | 226 +++++++ arch/arm/configs/stm32_defconfig | 71 ++ arch/arm/kernel/entry-v7m.S | 13 +- arch/arm/mach-stm32/Makefile | 1 + arch/arm/mach-stm32/Makefile.boot | 3 + arch/arm/mach-stm32/board-dt.c | 19 + arch/arm/mm/Kconfig | 15 + drivers/clocksource/Kconfig | 15 + drivers/clocksource/Makefile | 2 + drivers/clocksource/armv7m_systick.c | 79 +++ drivers/clocksource/timer-stm32.c | 184 ++++++ drivers/reset/Makefile | 1 + drivers/reset/reset-stm32.c | 124 ++++ drivers/tty/serial/Kconfig | 17 + drivers/tty/serial/Makefile | 1 + drivers/tty/serial/stm32-usart.c | 735 +++++++++++++++++++++ include/uapi/linux/serial_core.h | 3 + scripts/link-vmlinux.sh | 2 +- 30 files changed, 1852 insertions(+), 5 deletions(-) create mode 100644 Documentation/arm/stm32/overview.txt create mode 100644 Documentation/arm/stm32/stm32f429-overview.txt create mode 100644 Documentation/devicetree/bindings/arm/armv7m_systick.txt create mode 100644 Documentation/devicetree/bindings/reset/st,stm32-rcc.txt create mode 100644 Documentation/devicetree/bindings/serial/st,stm32-usart.txt create mode 100644 Documentation/devicetree/bindings/timer/st,stm32-timer.txt create mode 100644 arch/arm/boot/dts/stm32f429-disco.dts create mode 100644 arch/arm/boot/dts/stm32f429.dtsi create mode 100644 arch/arm/configs/stm32_defconfig create mode 100644 arch/arm/mach-stm32/Makefile create mode 100644 arch/arm/mach-stm32/Makefile.boot create mode 100644 arch/arm/mach-stm32/board-dt.c create mode 100644 drivers/clocksource/armv7m_systick.c create mode 100644 drivers/clocksource/timer-stm32.c create mode 100644 drivers/reset/reset-stm32.c create mode 100644 drivers/tty/serial/stm32-usart.c -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
