[U-Boot] [PATCH 2 00/22] DM: Cmd: GPIO/LED/STM32/CLK: provide command-line support for device-tree configured gpios and leds

[Benjamin Tietz]

This series begins to provide device-tree support on stm32 devices,
starting with a the stack of a simple clock-driver (at least
enabling/disabling peripheral clocks), the gpio driver and leds.

As the current led command-line interface isn't aware of any device-tree
configured led, the command gets rewritten and extended for device-tree LEDs
on the way. These changes are architecture indipendent.

To accomplish these changes the led-uclass driver had to be extended, too.

Changes in v2:
* more verbose commit messages
* correct clock calculation in stm32_clk
* minor adjustments

Benjamin Tietz (22):
      stm32: gpio: fix otype access
      stm32: gpio_direction_output: make sure, output is set to push-pull
      stm32: gpio_get_value: always return 0 or 1
      stm32f429-discovery: config: enable status leds
      Cmd: led: provide a selector in kconfig
      DTS: stm32f429: provide device-tree files (from linux kernel)
      clock-uclass: allow disabling a peripheral clock
      STM32: clock: provide dts-accessible clock driver
      DTS: STM32f429: add gpio-banks
      STM32: gpio: group SOC-specific code to one ifdef/elif construct
      GPIO: STM32: make DTS-aware
      STM32F429-discovery: led: disable board-specific code, if DM is selected
      GPIO/LED: make more robust, if STATUS_LED isn't selected
      Cmd: LED: rewrite to prepare non-static access
      DTS: STM32F429-disco: add board leds and enable rcc
      LED: add function to retrieve a device's label
      LED: provide function to count and get all (DM-)LEDs
      cmd: LED: be aware of DTS-configured leds
      LED: provide functionality to get led status
      LED: GPIO: provide get_on() op
      LED: provide toggling interface
      Cmd: LED: make DM-leds toggle
