Irina Tirdea d32f7fd3bb pinctrl: Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map
Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map, since
it does not depend on device tree despite the current name. This
will enforce a consistent naming in pinctr-utils.c and will make
it clear it can be called from outside device tree (e.g. from
ACPI handling code).

Paul Gortmaker b5576e08d1 pinctrl: stm32: make explicitly non-modular
The Kconfig currently controlling compilation of this code is:

drivers/pinctrl/stm32/Kconfig:config PINCTRL_STM32F429
drivers/pinctrl/stm32/Kconfig:  bool "STMicroelectronics STM32F429 pin control" if COMPILE_TEST && !MACH_STM32F429

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

Maxime Coquelin 38a3fbf16a pinctrl: stm32: Remove dependency with DT bindings header files
Some macros where defined in DT bindings headers, whereas only used
in the driver.

This patch moves these macros to the driver side.

Maxime Coquelin aceb16dc2d pinctrl: Add STM32 MCUs support
This patch adds pinctrl and GPIO support to STMicroelectronic's STM32
family of MCUs.

While it only supports STM32F429 for now, it has been designed to enable
support of other MCUs of the family (e.g. STM32F746).
