Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v5.1 cycle:
Core changes:
- The big change this time around is the irqchip handling in the
qualcomm pin controllers, closely coupled with the gpiochip. This
rework, in a classic fall-between-the-chairs fashion has been
sidestepped for too long.
The Qualcomm IRQchips using the SPMI and SSBI transport mechanisms
have been rewritten to use hierarchical irqchip. This creates the
base from which I intend to gradually pull support for hierarchical
irqchips into the gpiolib irqchip helpers to cut down on duplicate
code.
We have too many hacks in the kernel because people have been
working around the missing hierarchical irqchip for years, and once
it was there, noone understood it for a while. We are now slowly
adapting to using it.
This is why this pull requests include changes to MFD, SPMI,
IRQchip core and some ARM Device Trees pertaining to the Qualcomm
chip family. Since Qualcomm have so many chips and such large
deployments it is paramount that this platform gets this right, and
now it (hopefully) does.
- Core support for pull-up and pull-down configuration, also from the
device tree. When a simple GPIO chip supports an "off or on" pull-up
or pull-down resistor, we provide a way to set this up using
machine descriptors or device tree.
If more elaborate control of pull up/down (such as resistance shunt
setting) is required, drivers should be phased over to use pin
control. We do not yet provide a userspace ABI for this pull
up-down setting but I suspect the makers are going to ask for it
soon enough. PCA953x is the first user of this new API.
- The GPIO mockup driver has been revamped after some discussion
improving the IRQ simulator in the process.
The idea is to make it possible to use the mockup for both testing
and virtual prototyping, e.g. when you do not yet have a GPIO
expander to play with but really want to get something to develop
code around before hardware is available. It's neat. The blackbox
testing usecase is currently making its way into kernelci.
- ACPI GPIO core preserves non direction flags when updating flags.
- A new device core helper for devm_platform_ioremap_resource() is
funneled through the GPIO tree with Greg's ACK.
New drivers:
- TQ-Systems QTMX86 GPIO controllers (using port-mapped I/O)
- Gateworks PLD GPIO driver (vaccumed up from OpenWrt)
- AMD G-Series PCH (Platform Controller Hub) GPIO driver.
- Fintek F81804 & F81966 subvariants.
- PCA953x now supports NXP PCAL6416.
Driver improvements:
- IRQ support on the Nintendo Wii (Hollywood) GPIO.
- get_direction() support for the MVEBU driver.
- Set the right output level on SAMA5D2.
- Drop the unused irq trigger setting on the Spreadtrum driver.
- Wakeup support for PCA953x.
- A slew of cleanups in the various Intel drivers"

Pull char/misc driver updates from Greg KH:
"Here is the big char/misc driver patch pull request for 5.1-rc1.
The largest thing by far is the new habanalabs driver for their AI
accelerator chip. For now it is in the drivers/misc directory but will
probably move to a new directory soon along with other drivers of this
type.
Other than that, just the usual set of individual driver updates and
fixes. There's an "odd" merge in here from the DRM tree that they
asked me to do as the MEI driver is starting to interact with the i915
driver, and it needed some coordination. All of those patches have
been properly acked by the relevant subsystem maintainers.
All of these have been in linux-next with no reported issues, most for
quite some time"

This commit extends the flags that can be used in GPIO specifiers to
indicate if a pull-up resistor or pull-down resistor should be
enabled.
While some pinctrl DT bindings already offer the capability of
configuring pull-up/pull-down resistors at the pin level, a number of
simple GPIO controllers don't have any pinmuxing capability, and
therefore do not rely on the pinctrl DT bindings.
Such simple GPIO controllers however sometimes allow to configure
pull-up and pull-down resistors on a per-pin basis, and whether such
resistors should be enabled or not is a highly board-specific HW
characteristic.
By using two additional bits of the GPIO flag specifier, we can easily
allow the Device Tree to describe which GPIOs should have their
pull-up or pull-down resistors enabled. Even though the two options
are mutually exclusive, we still need two bits to encode at least
three states: no pull-up/pull-down, pull-up, pull-down.

Second set of new device support, features and cleanup for IIO in the 5.1 cycle.
There are a few late breaking fixes in here that weren't worth trying to
rush into 5.0 as they have been with us for quite a while.
New device support
* ad7476
- add support for TI ADS786X parts that are compatible with this Analog
Devices driver. Good to see some simple devices are so similar.
* Ingenic jz47xx SoC ADCs
- new driver and bindings
* Plantower PMS7003 partical sensor
- new driver and bindings including vendor prefix.
* TI DAC7612
- new driver and bindings for this dual DAC.
New features
* ad7768-1
- Sampling frequency control
* bmi160
- Data ready trigger support, including open-drain dt binding.
Cleanup / minor fixes.
* Analog Device DACs
- Fix some inconsistent licenses. These are only ones where there were
two different license marked in the same file, and hence were previously
unclear.
* ads124s08
- Spelling fix.
* adxl345
- Parameter alignement tidy up.
* bmi160
- SPDX
- correct a note on the types of supported interrupts which was too strict.
- use iio_pollfunc_store_time to grab an earlier timestamp.
- use if (ret) instead of if (ret < 0) to be consistent whilst simplifying
some handling where ret was effectively getting written to 0 even though
it was always already 0.
* exynos_adc
- Fix a null pointer dereference on unbind.
- Fix number of channels on Exynos4x12 devices to be 4 rather than 8.
* lpc32xx-adc
- Move DT bindings doc out of staging. Oops, I missed this one when
moving the driver.
- SPDX.
* npcm-adc
- drop documentation of reset node as going to be done differently.
It's a new driver this cycle so no need to support the previous
binding going forwards.
* sps30

"This is a bit larger than normal, as we had not managed to send out a
pull request before traveling for a week without my signing key.
There are multiple code fixes for older bugs, all of which should get
backported into stable kernels:
- tango: one fix for multiplatform configurations broken on other
platforms when tango is enabled
- arm_scmi: device unregistration fix
- iop32x: fix kernel oops from extraneous __init annotation
- pxa: remove a double kfree
- fsl qbman: close an interrupt clearing race
The rest is the usual collection of smaller fixes for device tree
files, on the renesas, allwinner, meson, omap, davinci, qualcomm and
imx platforms.
Some of these are for compile-time warnings, most are for board

It seems that the kernel has no business managing this clock: once the SP

Pretty sure nothing ever used this and it's safe to remove.

Pull ARM Device-tree updates from Olof Johansson:
"As usual, this is where the bulk of our changes end up landing each
merge window.
The individual updates are too many to enumerate, many many platforms
have seen additions of device descriptions such that they are
functionally more complete (in fact, this is often the bulk of updates
we see).
Instead I've mostly focused on highlighting the new platforms below as
they are introduced. Sometimes the introduction is of mostly a
fragment, that later gets filled in on later releases, and in some
cases it's near-complete platform support. The latter is more common
for derivative platforms that already has similar support in-tree.
Two SoCs are slight outliers from the usual range of additions.
Allwinner support for F1C100s, a quite old SoC (ARMv5-based) shipping
in the Lychee Pi Nano platform. At the other end is NXP Layerscape
LX2160A, a 16-core 2.2GHz Cortex-A72 SoC with a large amount of I/O
aimed at infrastructure/networking.
TI updates stick out in the diff stats too, in particular because they
have moved the description of their L4 on-chip interconnect to
devicetree, which opens up for removal of even more of their
platform-specific 'hwmod' description tables over the next few
releases.
SoCs:
- Qualcomm QCS404 (4x Cortex-A53)
- Allwinner T3 (rebranded R40) and f1c100s (armv5)
- NXP i.MX7ULP (1x Cortex-A7 + 1x Cortex-M4)
- NXP LS1028A (2x Cortex-A72), LX2160A (16x Cortex-A72)

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.21 kernel series.
Core changes:
- Some core changes are already in outside of this pull request as
they came through the regulator tree, most notably
devm_gpiod_unhinge() that removes devres refcount management from a
GPIO descriptor. This is needed in subsystems such as regulators
where the regulator core need to take over the reference counting
and lifecycle management for a GPIO descriptor.
- We dropped devm_gpiochip_remove() and devm_gpio_chip_match() as
nothing needs it. We can bring it back if need be.
- Add a global TODO so people see where we are going. This helps
setting the direction now that we are two GPIO maintainers.
- Handle the MMC CD/WP properties in the device tree core. (The bulk
of patches activating this code is already merged through the
MMC/SD tree.)
- Augment gpiochip_request_own_desc() to pass a flag so we as
gpiochips can request lines as active low or open drain etc even
from ourselves.
New drivers:
- New driver for Cadence GPIO blocks.
- New driver for Atmel SAMA5D2 PIOBU GPIO lines.
Driver improvements:
- A major refactoring of the PCA953x driver - this driver has been
around for ages, and is now modernized to reduce code duplication
that has stacked up and is using regmap to read write and cache
registers.
- Intel drivers are now maintained in a separate tree and start with
a round of cleanups and unifications"
