    Subject[PATCH v3 00/15] Add support to STMicroelectronics STM32 family
    Date
    From: Maxime Coquelin <mcoquelin.stm32@gmail.com>

    This third round tries to address most of the comments made on previous series.

    It contains few less patches, as the reset_controller_of_init() patch has been
    removed, now that the bootlaoder handles the reset of the timers.

    The pinctrl driver has also been removed after Linus review.
    It will be reworked to use the generic pinconf bindings, and may contain
    changes for other machines (Mediatek), to add support for pinmux property
    handling directly in pinconf-generic.

    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 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)
