Pull pin control updates from Linus Walleij:
"Pin control bulk changes for the v4.11 kernel cycle.
Core changes:
- Switch the generic pin config argument from 16 to 24 bits, only use
8 bits for the configuration type. We might need to encode more
information about a certain setting than we need to encode
different generic settings.
- Add a cross-talk API to the pin control GPIO back-end, utilizing
pinctrl_gpio_set_config() from GPIO drivers that want to set up a
certain pin configuration in the back-end.
This also includes the .set_config() refactoring of the GPIO chips,
so that they pass a generic configuration for things like
debouncing and single ended (typically open drain). This change has
also been merged in an immutable branch to the GPIO tree.
- Take hogs with a delayed work, so that we finalize probing a pin
controller before trying to get any hogs.
- For pin controllers putting all group and function definitions into
the device tree, we now have generic code to deal with this and it
is used in two drivers so far.
- Simplifications of the pin request conflict check.
- Make dt_free_map() optional.
Updates to drivers:
- pinctrl-single now use the generic helpers to generate dynamic
group and function tables from the device tree.
- Texas Instruments IOdelay configuration driver add-on to
pinctrl-single.
- i.MX: use radix trees to store groups and functions, use the new
generic group and function helpers to manage them.
- Intel: add support for hardware debouncing and 1K pull-down. New
subdriver for the Gemini Lake SoC.
- Renesas SH-PFC: drive strength and bias support, CAN bus muxing,
MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791.
- Aspeed: use syscon cross-dependencies to set up related bits in the
LPC host controller and display controller.
- Aspeed: finalize G4 and G5 support. Fix mux configuration on GPIOs.
Add banks Y, Z, AA, AB and AC.
- AMD: support additional GPIO.
- STM32: set this controller to strict muxing mode. STM32H743 MCU
support.
- Allwinner sunxi: deep simplifications on how to support subvariants
of SoCs without adding to much SoC-specific data for each
subvariant, especially for sun5i variants. New driver for V3s SoCs.
New driver for the H5 SoC. Support A31/A31s variants with the new
variant framework.
- Mvebu: simplifications to use a MMIO and regmap abstraction. New
subdrivers for the 98DX3236, 98DX5241 SoCs.
- Samsung Exynos: delete Exynos4415 support. Add crosstalk to the SoC
driver to access regmaps. Add infrastructure for pin-bank retention
control. Clean out the pin retention control from
arch/arm/mach-exynos and arch/arm/mach-s5p and put it properly in
the Samsung pin control driver(s).
- Meson: add HDMI HPD/DDC pins. Add pwm_ao_b pin.
- Qualcomm: use raw spinlock variants: this makes the qualcomm driver
realtime-safe"

The Armada 7K/8K use the same RTC IP than the Armada 38x. However the SOC
integration differs in 2 points:
- MBUS bridge timing initialization
- IRQ configuration at SoC level
Moreover the Armada 7K/8K have an issue preventing to get the interrupt
from alarm 1. This commit allows to use alarm 2 for these A7K/8K but to
still use alarm 1 for the Armada 38x.

According to using PHY framework, updates the exynos5440-pcie binding. For
maintaining backward compatibility, leaves the current dt-binding. (It
should be deprecated.)
Recommends to use the PHY Framework and "config" property to follow the
designware-pcie binding. If you use the old way, can see "missing *config*
reg space" message. Because the getting configuration space address from
range is old way.
NOTE: When use the "config" property, first name of 'reg-names' must be set
to "elbi". Otherwise driver can't maintain the backward capability.

Pull power management updates from Rafael Wysocki:
"The majority of changes go into the Operating Performance Points (OPP)
framework and cpufreq this time, followed by devfreq and some
scattered updates all over.
The OPP changes are mostly related to switching over from RCU-based
synchronization, that turned out to be overly complicated and
problematic, to reference counting using krefs.
In the cpufreq land there are core cleanups, documentation updates, a
new driver for Broadcom BMIPS SoCs, a new cpufreq-dt sub-driver for TI
SoCs that require special handling, ARM64 SoCs support for the qoriq
driver, intel_pstate updates, powernv driver update and assorted
fixes.
The devfreq changes are mostly fixes related to the sysfs interface
and some Exynos drivers updates.
Apart from that, the cpuidle menu governor will support per-CPU PM QoS
constraints for the wakeup latency now, some bugs in the wakeup IRQs
framework are fixed, the generic power domains framework should handle
asynchronous invocations of *noirq suspend/resume callbacks from now
on, the analyze_suspend.py script is updated and there is a new tool
for intel_pstate diagnostics.

In Tegra186, the BPMP (Boot and Power Management Processor) owns certain
HW devices, such as the I2C controller for the power management I2C bus.
Software running on other CPUs must perform IPC to the BPMP in order to
execute transactions on that I2C bus. This binding describes an I2C bus
that is accessed in such a fashion.

Add constants and callback functions for the dwmac on rk3328 socs.
As can be seen, the base structure is the same, only registers and the
bits in them moved slightly.

Display panels can be oriented many ways, especially in the embedded
world. The rotation property is a way to describe this orientation.
The counter clockwise direction is chosen because that's what fbdev
and drm use.

The Marvell devices may have many gpio pins, and hence for wakeup
on these out-of-band pins, the chip needs to be told which pin is
to be used for wakeup, using an hci command.
Thus, we read the pin number etc from the device tree node and send
a command to the chip.

Some onboard BT chips (e.g. Marvell 8997) contain a wakeup pin that
can be connected to a gpio on the CPU side, and can be used to wakeup
the host out-of-band. This can be useful in situations where the
in-band wakeup is not possible or not preferable (e.g. the in-band
wakeup may require the USB host controller to remain active, and
hence consuming more system power during system sleep).
The oob gpio interrupt to be used for wakeup on the CPU side, is
read from the device tree node, (using standard interrupt descriptors).
A devcie tree binding document is also added for the driver. The
compatible string is in compliance with
Documentation/devicetree/bindings/usb/usb-device.txt

This patch adds a driver for configuration of the Microchip USB251xB/xBi
USB 2.0 hub controller series with USB 2.0 upstream connectivity, SMBus
configuration interface and two to four USB 2.0 downstream ports.
Furthermore add myself as a maintainer for this driver.
The datasheet can be found at the manufacturers website, see [1]. All
device-tree exposed configuration features have been tested on a i.MX6
platform with a USB2512B hub.

This driver supports the Lantiq SSC SPI controller in master
mode. This controller is found on Intel (former Lantiq) SoCs like
the Danube, Falcon, xRX200, xRX300.
The hardware uses two hardware FIFOs one for received and one for
transferred bytes. When the driver writes data into the transmit FIFO
the complete word is taken from the FIFO into a shift register. The
data from this shift register is then written to the wire. This driver
uses the interrupts signaling the status of the FIFOs and not the shift
register. It is also possible to use the interrupts for the shift
register, but they will send a signal after every word. When using the
interrupts for the shift register we get a signal when the last word is
written into the shift register and not when it is written to the wire.
After all FIFOs are empty the driver busy waits till the hardware is
not busy any more and returns the transfer status.

Add a new compatible for sun4i-i2s driver to handle some
SoCs that have a reset line that must be asserted/deasserted.
This new compatible, "allwinner,sun6i-a31-i2s", requires the
property "resets" which should be a phandle to the reset line.
Except these differences, the compatible is identical to previous one
which will not handle a reset line.
