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 support a
"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.

Driver core patches for 5.1-rc1
Here is the big driver core patchset for 5.1-rc1 More patches than "normal" here this merge window, due to some work in the driver core by Alexander Duyck to rework the async probe functionality to work better for a number of devices, and independant work from Rafael for the device link functionality to make it work "correctly". Also in here is: - lots of BUS_ATTR() removals, the macro is about to go away - firmware test fixups - ihex fixups and simplification - component additions (also includes i915 patches) - lots of minor coding style fixups and cleanups.

Char/Misc driver patches for 5.1-rc1
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.

component: Add documentation
While typing these I think doing an s/component_master/aggregate/ would be useful: - it's shorter :-) - I think component/aggregate is much more meaningful naming than component/puppetmaster or something like that. At least to my English ear "aggregate" emphasizes much more the "assemble a pile of things into something bigger" aspect, and there's not really much of a control hierarchy between aggregate and constituing components. But that's way more than a quick doc typing exercise ... Thanks to Ram for commenting on an initial draft of these docs. v2: Review from Rafael: - git add Documenation/driver-api/component.rst - lots of polish to the wording + spelling fixes. v3: Review from Russell: - s/framework/helper - clarify the documentation for component_match_add functions. v4: Remove a few superflous "This".

driver core: Document limitation related to DL_FLAG_RPM_ACTIVE
If device_link_add() is called twice in a row to create a stateless device link for the same consumer-supplier pair without an attempt to delete the link between these calls, and the second caller passes DL_FLAG_RPM_ACTIVE to it in flags, calling either device_link_del() or device_link_remove() immediately after that will leave the link's supplier device with nonzero PM-runtime usage counter, which may prevent the supplier from being runtime-suspended going forward until the link is deleted by another invocation of device_link_del() or device_link_remove() for it. Even though this is confusing and may lead to subtle issues, trying to avoid it in the framework also may cause problems to appear, so document it as a known limitation. Signed-off-by: Rafael J.

driver core: Add device link flag DL_FLAG_AUTOPROBE_CONSUMER
Add a new device link flag, DL_FLAG_AUTOPROBE_CONSUMER, to request the driver core to probe for a consumer driver automatically after binding a driver to the supplier device on a persistent managed device link. As unbinding the supplier driver on a managed device link causes the consumer driver to be detached from its device automatically, this flag provides a complementary mechanism which is needed to address some "composite device" use cases.

driver core: Make driver core own stateful device links
Even though stateful device links are managed by the driver core in principle, their creators are allowed and sometimes even expected to drop references to them via device_link_del() or device_link_remove(), but that doesn't really play well with the "persistent" link concept. If "persistent" managed device links are created from driver probe callbacks, device_link_add() called to do that will take a new reference on the link each time the callback runs and those references will never be dropped, which kind of isn't nice. This issues arises because of the link reference counting carried out by device_link_add() for existing links, but that is only done to avoid deleting device links that may still be necessary, which shouldn't be a concern for managed (stateful) links. These device links are managed by the driver core and whoever creates one of them will need it at least as long as until the consumer driver is detached from its device and deleting it may be left to the driver core just fine. For this reason, rework device_link_add() to apply the reference counting to stateless links only and make device_link_del() and device_link_remove() drop references to stateless links only too. After this change, if called to add a stateful device link for a consumer-supplier pair for which a stateful device link is present already, device_link_add() will return the existing link without incrementing its reference counter. Accordingly, device_link_del() and device_link_remove() will WARN() and do nothing when called to drop a reference to a stateful link. Thus, effectively, all stateful device links will be owned by the driver core. In addition, clean up the handling of the link management flags, DL_FLAG_AUTOREMOVE_CONSUMER and DL_FLAG_AUTOREMOVE_SUPPLIER, so that (a) they are never set at the same time and (b) if device_link_add() is called for a consumer-supplier pair with an existing stateful link between them, the flags of that link will be combined with the flags passed to device_link_add() to ensure that the life time of the link is sufficient for all of the callers of device_link_add() for the same consumer-supplier pair. Update the device_link_add() kerneldoc comment to reflect the above changes. Signed-off-by: Rafael J.

driver core: Fix adding device links to probing suppliers
Currently, it is not valid to add a device link from a consumer driver ->probe callback to a supplier that is still probing too, but generally this is a valid use case. For example, if the consumer has just acquired a resource that can only be available if the supplier is functional, adding a device link to that supplier right away should be safe (and even desirable arguably), but device_link_add() doesn't handle that case correctly and the initial state of the link created by it is wrong then. To address this problem, change the initial state of device links added between a probing supplier and a probing consumer to DL_STATE_CONSUMER_PROBE and update device_links_driver_bound() to skip such links on the supplier side. With this change, if the supplier probe completes first, device_links_driver_bound() called for it will skip the link state update and when it is called for the consumer, the link state will be updated to "active". In turn, if the consumer probe completes first, device_links_driver_bound() called for it will change the state of the link to "active" and when it is called for the supplier, the link status update will be skipped. However, in principle the supplier or consumer probe may still fail after the link has been added, so modify device_links_no_driver() to change device links in the "active" or "consumer probe" state to "dormant" on the supplier side and update __device_links_no_driver() to change the link state to "available" only if it is "consumer probe" or "active". Then, if the supplier probe fails first, the leftover link to the probing consumer will become "dormant" and device_links_no_driver() called for the consumer (when its probe fails) will clean it up. In turn, if the consumer probe fails first, it will either drop the link, or change its state to "available" and, in the latter case, when device_links_no_driver() is called for the supplier, it will update the link state to "dormant". [If the supplier probe fails, but the consumer probe succeeds, which should not happen as long as the consumer driver is correct, the link still will be around, but it will be "dormant" until the supplier is probed again.] Signed-off-by: Rafael J.

Char/Misc driver patches for 4.21-rc1
Here is the big set of char and misc driver patches for 4.21-rc1.
Lots of different types of driver things in here, as this tree seems to
be the "collection of various driver subsystems not big enough to have
their own git tree" lately.
Anyway, some highlights of the changes in here:
- binderfs: is it a rule that all driver subsystems will eventually
grow to have their own filesystem? Binder now has one to handle the
use of it in containerized systems. This was discussed at the
Plumbers conference a few months ago and knocked into mergable shape
very fast by Christian Brauner. Who also has signed up to be
another binder maintainer, showing a distinct lack of good judgement :)
- binder updates and fixes
- mei driver updates
- fpga driver updates and additions
- thunderbolt driver updates
- soundwire driver updates
- extcon driver updates
- nvmem driver updates
- hyper-v driver updates
- coresight driver updates
- pvpanic driver additions and reworking for more device support
- lp driver updates. Yes really, it's _finally_ moved to the proper
parallal port driver model, something I never thought I would see
happen. Good stuff.
- other tiny driver updates and fixes.
All of these have been in linux-next for a while with no reported
issues.

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.

This is the bulk of GPIO changes for the v4.20 series:
Core changes:
- A patch series from Hans Verkuil to make it possible to
enable/disable IRQs on a GPIO line at runtime and drive GPIO
lines as output without having to put/get them from scratch.
The irqchip callbacks have been improved so that they can
use only the fastpatch callbacks to enable/disable irqs
like any normal irqchip, especially the gpiod_lock_as_irq()
has been improved to be callable in fastpath context.
A bunch of rework had to be done to achieve this but it is
a big win since I never liked to restrict this to slowpath.
The only call requireing slowpath was try_module_get() and
this is kept at the .request_resources() slowpath callback.
In the GPIO CEC driver this is a big win sine a single
line is used for both outgoing and incoming traffic, and
this needs to use IRQs for incoming traffic while actively
driving the line for outgoing traffic.
- Janusz Krzysztofik improved the GPIO array API to pass a
"cookie" (struct gpio_array) and a bitmap for setting or
getting multiple GPIO lines at once. This improvement
orginated in a specific need to speed up an OMAP1 driver and
has led to a much better API and real performance gains
when the state of the array can be used to bypass a lot
of checks and code when we want things to go really fast.
The previous code would minimize the number of calls
down to the driver callbacks assuming the CPU speed was
orders of magnitude faster than the I/O latency, but this
assumption was wrong on several platforms: what we needed
to do was to profile and improve the speed on the hot
path of the array functions and this change is now
completed.
- Clean out the painful and hard to grasp BNF experiments
from the device tree bindings. Future approaches are looking
into using JSON schema for this purpose. (Rob Herring
is floating a patch series.)
New drivers:
- The RCAR driver now supports r8a774a1 (RZ/G2M).
- Synopsys GPIO via CREGs driver.
Major improvements:
- Modernization of the EP93xx driver to use irqdomain and
other contemporary concepts.
- The ingenic driver has been merged into the Ingenic pin
control driver and removed from the GPIO subsystem.
- Debounce support in the ftgpio010 driver.

PCI/P2PDMA: Add P2P DMA driver writer's documentation
Add a restructured text file describing how to write drivers with support for P2P DMA transactions. The document describes how to use the APIs that were added in the previous few commits. Also adds an index for the PCI documentation tree even though this is the only PCI document that has been converted to restructured text at this time.

docs: fpga: document programming fpgas using regions
Clarify the intention that interfaces and upper layers use regions rather than managers directly. Rearrange API documentation to better group the API functions used to create FPGA mgr/bridge/regions and the API used for programming FPGAs.
