Intel Cedar Fork PCH is the successor of Intel Denverton PCH but it is
based on the newer GPIO/pinctrl hardware block. Add a new pinctrl/GPIO
driver to support it.

Instead of depends on GPIOLIB and having to run around in
Kconfig menus looking for why your device is not available,
simply select it from the pin control drivers that need it.
The Kconfig for GPIOLIB is improved, selectable and this
should "just work".

Intel Lewisburg has the same GPIO hardware than Intel Sunrisepoint-H
except few differences in register offsets and pin lists. Because of
this we add a separate pinctrl driver for Lewisburg.

This driver adds pinctrl/GPIO support for Intel Denverton SoC. The GPIO
controller is based on the same hardware design that is already used in
Intel Sunrisepoint so we leverage the core driver here.

The Intel pin control drivers are architecture specific so add an if arch
to check for X86 or compile test to ensure continued test coverage.

This adds pinctrl/GPIO support for Intel Cannon Lake PCH. The Cannon
Lake PCH GPIO is based on newer version of the Intel GPIO hardware.

This driver adds pinctrl/GPIO support for Intel Gemini Lake SoC. The
GPIO controller is based on the next generation GPIO hardware but still
compatible with the one supported by the Intel core pinctrl/GPIO driver.
This commit includes material from David E. Box.

This driver adds pinctrl support for Intel Merrifield. The IP block which is
called Family-Level Interface Shim is a separate entity in SoC. The GPIO driver
(gpio-intel-mid.c) will be updated accordingly to support pinctrl interface.

Add implementation for:
- pin control, group information retrieval: count, name and pins
- pin muxing:
- function information (count, name and groups)
- mux setting
- gpio control (enable, disable, set direction)
- pin configuration:
- pull disable
- pull up/down and pull strength
- debounce
- any other option is treated as not supported.

This driver supports pinctrl/GPIO hardware found on Intel Sunrisepoint (a
Skylake PCH) providing users a pinctrl and GPIO interfaces (including GPIO
interrupts).
The driver is split into core and platform parts so that the same core
driver can be reused in other drivers for other Intel GPIO hardware that is
based on the same host controller design.

This driver supports the pin/GPIO controllers found in newer Intel SoCs
like Cherryview and Braswell. The driver provides full GPIO support and
minimal set of pin controlling funtionality.
The driver is based on the original Cherryview GPIO driver authored by Ning
Li and Alan Cox.

We are going to have more pinctrl drivers for Intel hardware so separate
all our pin controller drivers to own directory.
