This ninth round counts less patches as some have already been applied, and the reset driver will be part of another series because it will introduce a generic reset driver to be used by several SoCs (sunxi, socfpga). Main change in remaining patches is the rework of the STM32 clocksource Kconfig entry. 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. Changes since v8: ----------------- - Rework clocksource driver Kconfig entry. - Remove reset driver from the series. Changes since v7: ----------------- - Add DT-bindings header file for RCC IP (Daniel) - Fix uninitialized variables in serial driver - Enable CONFIG_NO_HZ in stm32_defconfig Changes since v6: ----------------- - serial: Fix locking in case of sysrq (Vladimir) - Rebase on top of v4.1-rc1 - Apply Acked-by and Reviewed-by - Clean-up stm32_defconfig 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 (5): 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: dts: Introduce STM32F429 MCU .../devicetree/bindings/serial/st,stm32-usart.txt | 32 + .../devicetree/bindings/timer/st,stm32-timer.txt | 22 + arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/stm32f429-disco.dts | 71 ++ arch/arm/boot/dts/stm32f429.dtsi | 214 ++++++ drivers/clocksource/Kconfig | 5 + drivers/clocksource/Makefile | 1 + drivers/clocksource/timer-stm32.c | 184 +++++ drivers/tty/serial/Kconfig | 17 + drivers/tty/serial/Makefile | 1 + drivers/tty/serial/stm32-usart.c | 739 +++++++++++++++++++++ include/uapi/linux/serial_core.h | 3 + 12 files changed, 1290 insertions(+) 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 drivers/clocksource/timer-stm32.c create mode 100644 drivers/tty/serial/stm32-usart.c -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
