Subject[PATCH v9 0/5] Add support to STMicroelectronics STM32 family
Date
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
