The pin controller on ZTE ZX platforms is kinda of hybrid. It consists
of a main controller and an auxiliary one. For example, on ZX296718 SoC,
the main controller is TOP_PMM and the auxiliary one is AON_IOCFG. Both
controllers work together to control pin multiplexing and configuration.
For most of pins, the pinmux function is controlled by main controller
only, and this type of pins are meant by term 'TOP pins'. For other
pins, the pinmux is controlled by both main and auxiliary controllers,
as the available multiplexing functions for the pin spread in both
controllers. This type of pins are called 'AON pins'. Though pinmux
implementation is quite different, pinconf is same for both types of
pins. Both are controlled by auxiliary controller, i.e. AON_IOCFG on
ZX296718.
The patch adds the ZTE ZX core pinctrl driver to support this hybrid
pin controller as well as ZX296718 SoC specific pin data.

The Armada 37xx SoC come with 2 pin controllers: one on the south
bridge (managing 28 pins) and one on the north bridge (managing 36 pins).
At the hardware level the controller configure the pins by group and not
pin by pin. This constraint is reflected in the design of the driver:
only the group related functions are implemented.

SoC family such as DRA7 family of processors have, in addition
to the regular muxing of pins (as done by pinctrl-single), a separate
hardware module called IODelay which is also expected to be configured.
The "IODelay" module has it's own register space that is independent
of the control module and the padconf register area.
With recent changes to the pinctrl framework, we can now support
this hardware with a reasonably minimal driver by using #pinctrl-cells,
GENERIC_PINCTRL_GROUPS and GENERIC_PINMUX_FUNCTIONS.
It is advocated strongly in TI's official documentation considering
the existing design of the DRA7 family of processors during mux or
IODelay reconfiguration, there is a potential for a significant glitch
which may cause functional impairment to certain hardware. It is
hence recommended to do as little of muxing as absolutely necessary
without I/O isolation (which can only be done in initial stages of
bootloader).
NOTE: with the system wide I/O isolation scheme present in DRA7 SoC
family, it is not reasonable to do stop all I/O operations for every
such pad configuration scheme. So, we will let it glitch when used in
this mode.
Even with the above limitation, certain functionality such as MMC has
mandatory need for IODelay reconfiguration requirements, depending on
speed of transfer. In these cases, with careful examination of usecase
involved, the expected glitch can be controlled such that it does not
impact functionality.
In short, IODelay module support as a padconf driver being introduced
here is not expected to do SoC wide I/O Isolation and is meant for
a limited subset of IODelay configuration requirements that need to
be dynamic and whose glitchy behavior will not cause functionality
failure for that interface.
IMPORTANT NOTE: we take the approach of keeping LOCK_BITs cleared
to 0x0 at all times, even when configuring Manual IO Timing Modes.
This is done by eliminating the LOCK_BIT=1 setting from Step
of the Manual IO timing Mode configuration procedure. This option
leaves the CFG_* registers unprotected from unintended writes to the
CTRL_CORE_PAD_* registers while Manual IO Timing Modes are configured.
This approach is taken to allow for a generic driver to exist in kernel
world that has to be used carefully in required usecases.

Since the I2C sx150x GPIO expander driver uses platform_data to manage
the pins configurations, rewrite the driver as a pinctrl driver using
pinconf to get/set pin configurations from DT or debugfs.
The pinctrl driver is functionnally equivalent as the gpio-only driver
and can use DT for pinconf. The platform_data confirmation is dropped.
This patchset removed the gpio-only driver and selects the Pinctrl driver
config instead. This patchset also migrates the gpio dt-bindings to pinctrl
and add the pinctrl optional properties.
The driver was tested with a SX1509 device on a BeagleBone black with
interrupt support and on an X86_64 machine over an I2C to USB converter.
This is a fixed version that builds and runs on non-OF platforms and on
arm based OF. The GPIO version is removed and the bindings are also moved
to the pinctrl bindings.
Changes since v2
- rebased on v4.9-rc1
- removed MODULE_DEVICE_TABLE as in upstream bb411e771b0e
("gpio: sx150x: fix implicit assumption module.h is present")
Changes since v1
- Fix Kconfig descriptions on pinctrl and gpio
- Fix Kconfig dependency
- Remove oscio support for non-789 devices
- correct typo in dt bindings
- remove probe reset for non-789 devices
Changes since RFC
- Put #ifdef CONFIG_OF/CONFIG_OF_GPIO to remove OF code for non-of platforms
- No more rely on OF_GPIO config
- Moved and enhanced bindings to pinctrl bindings
- Removed gpio-sx150x.c
- Temporary select PINCTRL_SX150X when GPIO_SX150X
- Temporary mark GPIO_SX150X as deprecated

The Aspeed SoCs typically provide more than 200 pins for GPIO and other
functions. The signal enabled on a pin is determined on a priority
basis, where a given pin can provide a number of different signal types.
In addition to the priority levels, the Aspeed pin controllers describe
the signal active on a pin by compound logical expressions involving
multiple operators, registers and bits. Some difficulty arises as a
pin's function bit masks for each priority level are frequently not the
same (i.e. we cannot just flip a bit to change from a high to low
priority signal), or even in the same register(s). Some configuration
bits affect multiple pins, while in other cases the signals for a bus
must each be enabled individually.
Together, these features give rise to some complexity in the
implementation. A more complete description of the complexities is
provided in the associated header file.
The patch doesn't implement pinctrl/pinmux/pinconf for any particular
Aspeed SoC, rather it adds the framework for defining pinmux
configurations.

drivers/pinctrl/bcm/Makefile properly builds individual drivers based on

"Unlike the board branch, this keeps having large sets of changes for
every release, but that's quite expected and is so far working well.
Most of this is plumbing for various device bindings and new
platforms, but there's also a bit of cleanup and code removal for
things that are moved from platform code to DT contents (some OMAP
clock code in particular).
There's also a pinctrl driver for tegra here (appropriately acked),
that's introduced this way to make it more bisectable.
I'm happy to say that there were no conflicts at all with this branch
this release, which means that changes are flowing through our tree as
expected instead of merged through driver maintainers (or at least not
done with conflicts).
There are several new boards added, and a couple of SoCs. In no
particular order:
- Rockchip RK3288 SoC support, including DTS for a dev board that
they have seeded with some community developers.
- Better support for Hardkernel Exynos4-based ODROID boards.
- CCF conversions (and dtsi contents) for several Renesas platforms.
- Gumstix Pepper (TI AM335x) board support
- TI eval board support for AM437x
- Allwinner A23 SoC, very similar to existing ones which mostly has
resulted in DT changes for support. Also includes support for an
Ippo tablet with the chipset.
- Allwinner A31 Hummingbird board support, not to be confused with
the SolidRun i.MX-based Hummingboard.
- Tegra30 Apalis board support"

The XUSB pad controller found on NVIDIA Tegra SoCs provides several pads
that lanes can be assigned to in order to support a variety of interface
options: USB 2.0, USB 3.0, PCIe and SATA.
In addition to the pin controller used to assign lanes to pads two PHYs
are exposed to allow the bricks for PCIe and SATA to be powered up and
down by PCIe and SATA drivers.
