Michael Hope 0a5725e858 pinmux: sam0: add a pinmux driver for the SAM0 series.
Pin multiplexing is a function of the PORT peripheral.  This change
defines a separate pinmux device at the same address as the PORTs
themselves.

Maureen Helm 4973787c10 pinmux: Remove the k64 pinmux driver
The k64 pinmux driver was deprecated when the more generic mcux pinmux
driver was added, but it can actually just be removed because it is not
a public interface. Applications should be using the public pinmux API,
not the private k64 pinmux API. There was one case in the net samples
that used the private API which was cleaned up in a previous patch.

Maureen Helm a4e823eee0 pinmux: Introduce new ksdk pinmux driver
Kinetis SoCs contain one or more PORT modules to handle pin muxing and
pin configuration. Unlike the existing k64 pinmux driver, this driver
handles each PORT module individually and can be used for other Kinetis
SoCs.

This driver uses KSDK CMSIS register accesses to the PORT module rather
than the KSDK PORT driver (fsl_port.h), because the Zephyr pinmux
interface contains both set() and get() functions to access the pin
configuration. The KSDK PORT driver only contains a set() function
(which is a very thin static inline function to modify the PCR
register), therefore building a shim on top of it would result in a
strange mix of using the KSDK PORT driver for the set() and a direct
CMSIS register access for the get().

Paul Sokolovsky 6b2a1af1cd pinmux: Make default init priority be between GPIO's prio and device prio.
Pinmux driver almost certainly should be initialized before the
rest of hardware devices (which may need specific pins already
configured for them), and usually after generic GPIO drivers.
Thus, its priority should be between KERNEL_INIT_PRIORITY_DEFAULT
(default 40) and KERNEL_INIT_PRIORITY_DEVICE (default 50). Thus,
we set PINMUX_INIT_PRIORITY to 45.

There are exceptions to the rule above for particular boards. For
example, BOARD=galileo has GPIO and pinmuxer on I2C bus and thus
overrides PINMUX_INIT_PRIORITY to be much higher. Note that while
PINMUX_INIT_PRIORITY was defined previously (at 60), it was used
only for galileo, which overrides it anyway.

This fix was prompted by investigation why eth_ksdk driver was
non-functional after kernel priorities re-hashing: both eth_ksdk
and pinmux used the same priority, and eth_ksdk happened to run
before pinmux. While bumping eth_ksdk priority would help in the
particular case, the same would likely reoccur with other drivers
like I2C, SPI, etc.

Daniel Leung cecc4b0fb5 pinmux: remove base address and number of pins from kconfig
The pinmux base address and number of pins are now defined in SoC or board
header files instead of specifying them in kconfig. This is because
the pinmux ties directly to the SoC (or board expanders) so the base
address and number of pins do not need to be configurable in kconfig.

Vinicius Costa Gomes 05cbf0b20b pinmux_dev: Add the pinmux_dev driver for Atmel SAM3X
This introduces the pinmux_dev driver for the Atmel SAM3X.

This driver implements what used to be the pinmux driver API, which
applications could use to modify the function of pins during runtime.

That functionality is now protected under the CONFIG_PINMUX_DEV option,
which should only be set during the early enabling of a new board, as
there is risk of damage to the board when misused.

Vinicius Costa Gomes ed6fc400e9 pinmux: Move the Arduino 101 board to the pinmux model
This driver doesn't provide any API, it only initializes the pinmux
controller to appropriate values depending on the board.

The first board to use this new infrastructure is the Arduino 101 board,
because it is alphabetically the first.

To better organize code for the different SoCs and boards, a "family"
level is created in the 'drivers/pinmux' directory. The Arduino 101
board is part of the Quark MCU "family".

The PINMUX_DEV configuration (and functionality) is removed for now, it
will be added back when the pinmux_dev drivers are (re)introduced, with
clearer semantics.

Maciek Borzecki e53390f02d pinmux/stm32: add common driver for STM32 pinmux
Add a common driver for pin control subsystem in STM32 MCU series. The
driver allows for selection of pin's function without the ability of pin
remapping.

The driver implements a pinmux driver API, with custom `func` and `pin`
encoding in API calls. The caller is expected to use STM32PIN() helper
macro for encoding port/pin numbers or using one of the provided
STM32_PIN_* defines.

The common driver requires SoC specific support to be implemented. The
SoC code must implement these calls: stm32_get_pin_config(),
stm32_get_port_clock(), stm32_pin_configure(). Consult pinmux_stm32.h
header for detailn on semantics of these calls.

The driver also requires board level integration. The call
stm32_board_get_pinconf() is expected to privide pin function
assignments for the target board.

Whenever an IO pin is being enabled, the driver will automatically
enable the clock for corresponding port. The driver does not implement
disabling of port's clock as this has potentially disruptive, as such
such operation should be done explicitly in the code.

The pin control module needs to be initialized before any other modules,
but after clock_control. For this reason, the driver is initialized by
default at PRIMARY level, with priority set to 2. The priority can be
changed through configuration.

Jeff Blais 52b499fd1f arm: Freescale K64/FRDM-K64F Pinmux support
K64 pinmux support is created as a normal driver.

As opposed to the Galileo board, the pin configuration options are
defined by the MCU and are not board-specific.  Separate
platform/board-specific configuration code uses the pinmux driver for
the default pin settings. For FRDM-K64F, only the Arduino pins (22 of a
possible 160) are set up.

Some of the I/O pins routed to the Arduino header are also configured as
JTAG/SWD signals by default and are used by the OpenSDAv2 debug
interface.  Therefore, a PRESERVE_JTAG_IO_PINS config option was created
for the FRDM-K64 platform to prevent the default pin settings from
re-configuring these pins.

The K64 MCU separates pin configuration and control, implemented in the
pinmux driver, from GPIO.  This results in some cross referencing
between the K64 GPIO driver and the K64 pinmux driver due to the
dependencies of one on the other.

This pinmux driver also uses the expanded pinmux function/mode parameter
size to describe pin configuration options with bit fields for the K64,
including up to 8 pin functions, plus interrupt, pullup/down, drive
strength, open-drain and slew rate.

The following GCC warnings in the K64 pinmux driver are prevented when not
compiling with 'no-optimization' (-O0):

warning: 'gpio_dev' may be used uninitialized in this function
[-Wmaybe-uninitialized]
