gpiolib: acpi: Add quirk to ignore EC wakeups on Dell Venue 10 Pro 5055
[ Upstream commit da91ece226729c76f60708efc275ebd4716ad089 ] Like some other Bay and Cherry Trail SoC based devices the Dell Venue 10 Pro 5055 has an embedded-controller which uses ACPI GPIO events to report events instead of using the standard ACPI EC interface for this. The EC interrupt is only used to report battery-level changes and it keeps doing this while the system is suspended, causing the system to not stay suspended. Add an ignore-wake quirk for the GPIO pin used by the EC to fix the spurious wakeups from suspend.

gpiolib: acpi: Allow to find GpioInt() resource by name and index
commit 809390219fb9c2421239afe5c9eb862d73978ba0 upstream. Currently only search by index is supported. However, in some cases we might need to pass the quirks to the acpi_dev_gpio_irq_get(). For this, split out acpi_dev_gpio_irq_get_by() and replace acpi_dev_gpio_irq_get() by calling above with NULL for name parameter. Fixes: |

gpiolib: acpi: Add ACPI_GPIO_QUIRK_ABSOLUTE_NUMBER quirk
commit 62d5247d239d4b48762192a251c647d7c997616a upstream. On some systems the ACPI tables has wrong pin number and instead of having a relative one it provides an absolute one in the global GPIO number space. Add ACPI_GPIO_QUIRK_ABSOLUTE_NUMBER quirk to cope with such cases. Fixes: |

GPIO bulk changes for the v5.10 kernel cycle:
Core changes:
- The big core change is the updated (v2) userspace character
device API. This corrects badly designed 64-bit alignment around
the line events. We also add the debounce request feature.
This echoes the often quotes passage from Frederick Brooks
"The mythical man-month" to always throw one away, which we
have seen before in things such as V4L2. So we put in a new
one and deprecate and obsolete the old one.
- All example tools in tools/gpio/* are migrated to the new API
to set a good example. The libgpiod userspace library has been
augmented to use this new API pretty much from day 1.
- Some misc API hardening by using strn* function calls has been
added as well.
- Use the simpler IDA interface for GPIO chip instance enumeration.
- Add device core function for counting string arrays in
device properties.
- Provide a generic library function kfree_strarray() that can
be used throughout the kernel.
Driver enhancements:
- The DesignWare dwapb-gpio driver has been enhanced and now
uses the IRQ handling in the gpiolib core.
- The mockup and aggregator drivers have seen some substantial
code clean-up and now use more of the core kernel
inftrastructure.
- Misc cleanups using dev_err_probe().
- The MXC drivers (Freescale/NXP) can now be built modularized,
which makes modularized GKI Android kernels happy.

Pull GPIO updates from Linus Walleij:
"This time very little driver changes but lots of core changes.
We have some interesting cooperative work for ARM and Intel alike,
making the GPIO subsystem more and more suitable for industrial
systems and the like, in addition to the in-kernel users.
We touch driver core (device properties) and lib/* by adding one
simple string array free function, these are authored by Andy
Shevchenko who is a well known and recognized core helpers maintainers
so this should be fine.
We also see some Android GKI-related modularization in the MXC

gpiolib: generalize devprop_gpiochip_set_names() for device properties
devprop_gpiochip_set_names() is overly complicated with taking the fwnode argument (which requires using dev_fwnode() & of_fwnode_handle() in ACPI and OF GPIO code respectively). Let's just switch to using the generic device properties. This allows us to pull the code setting line names directly into gpiochip_add_data_with_key() instead of handling it separately for ACPI and OF.

gpiolib: acpi: Add quirk to ignore EC wakeups on HP x2 10 CHT + AXP288 model
There are at least 3 models of the HP x2 10 models:
Bay Trail SoC + AXP288 PMIC
Cherry Trail SoC + AXP288 PMIC
Cherry Trail SoC + TI PMIC
Like on the other HP x2 10 models we need to ignore wakeup for ACPI GPIO
events on the external embedded-controller pin to avoid spurious wakeups
on the HP x2 10 CHT + AXP288 model too.
This commit adds an extra DMI based quirk for the HP x2 10 CHT + AXP288
model, ignoring wakeups for ACPI GPIO events on the EC interrupt pin
on this model. This fixes spurious wakeups from suspend on this model.

gpiolib: acpi: Add honor_wakeup module-option + quirk mechanism
On some laptops enabling wakeup on the GPIO interrupts used for ACPI _AEI event handling causes spurious wakeups. This commit adds a new honor_wakeup option, defaulting to true (our current behavior), which can be used to disable wakeup on troublesome hardware to avoid these spurious wakeups. This is a workaround for an architectural problem with s2idle under Linux where we do not have any mechanism to immediately go back to sleep after wakeup events, other then for embedded-controller events using the standard ACPI EC interface, for details see: https://lore.kernel.org/linux-acpi/61450f9b-cbc6-0c09-8b3a-aff6bf9a0b3c@redhat.com/ One series of laptops which is not able to suspend without this workaround is the HP x2 10 Cherry Trail models, this commit adds a DMI based quirk which makes sets honor_wakeup to false on these models.

This is the bulk of GPIO changes for the v5.5 kernel cycle
Core changes:
- Expose pull up/down flags for the GPIO character device to
userspace. After clear input from the RaspberryPi and Beagle
communities, it has been established that prototyping,
industrial automation and make communities strongly need
this feature, and as we want people to use the character
device, we have implemented the simple pull up/down
interface for GPIO lines. This means we can specify that
a (chip-specific) pull up/down resistor can be enabled,
but does not offer fine-grained control such as cases
where the resistance of the same pull resistor can be
controlled (yet).
- Introduce devm_fwnode_gpiod_get_index() and start to phase out
the old symbol devm_fwnode_get_index_gpiod_from_child().
- A bit of documentation clean-up work.
- Introduce a define for GPIO line directions and deploy it
in all GPIO drivers in the drivers/gpio directory.
- Add a special callback to populate pin ranges when
cooperating with the pin control subsystem and registering
ranges as part of adding a gpiolib driver and a
gpio_irq_chip driver at the same time. This is also
deployed in the Intel Merrifield driver.
New drivers:
- RDA Micro GPIO controller.
- XGS-iproc GPIO driver.
Driver improvements:
- Wake event and debounce support on the Tegra 186 driver.
- Finalize the Aspeed SGPIO driver.
- MPC8xxx uses a normal IRQ handler rather than a chained
handler.

This is the bulk of changes in the GPIO subsystem for the
v5.4 kernel cycle.
Core changes:
- Support hierarchical GPIO irqchips. We now have three
consumers that can use this: Intel IXP4xx, ThunderX and
Qualcomm SPMI GPIO (in the pinctrl subsystem). The support
code has been long in the making and hashed out so it should
be easily adaptable for all hierarchical irqchip parents.
The code only gets compiled in if hierarchical irqchip
is used at the topmost irq controller at least, as the
hierarchical irqchip requires strict hierarchy all the
way up in the system.
- Determine the need for a "valid_mask" for GPIO lines on the
gpio_chip and conversely for the "valid_mask" for the GPIO
interrupt chip interrupt lines by looking for a
.init_valid_mask() callback in the main chip or GPIO interrupt
chip respectively. Allocate it with bitmap_alloc().
- Isolate the device tree/open firmware GPIO description code
out in its own file properly.
- Isolate the ACPI GPIO description code out in its own file
properly.
- Drop a whole lot of #ifdef:s in the main includes: it does
not hurt to keep the include items around, and we get
quicker and clearer compile failures if the appropriate
kernel symbols are not selected for drivers.
New/deleted drivers:
- New driver for Aspeed SGPIO.
- The KS8695 driver is deleted as the platform gets deleted
from arch/arm in this kernel cycle.
- The Cirrus Logic Madera driver now supports CS47L92 and
CS47L15.
- The Freescale MPC8xxx now supports LS1028A and LS1088A.
Driver improvements:
- We pass the GPIO irqchip intialization by directly filling
in the struct instead of using set-up functions (the new
way) for Intel MID, Lynxpoint, Merrifield, XLP, HLWD, Aspeed,
ZX, VF610, TQMX86, MT7621, Zynq and EP93xx.
Out-of-band changes:
- Fix a GPIO header inclusion in Unicore - no response from
maintainer.
- Drop FMC subsystem from MAINTAINERS - was deleted in the
GPIO tree last cycle so let's mop up the shards.

the topmost irq controller at least, as the hierarchical irqchip
requires strict hierarchy all the way up in the system.
- Determine the need for a "valid_mask" for GPIO lines on the
gpio_chip and conversely for the "valid_mask" for the GPIO
interrupt chip interrupt lines by looking for a .init_valid_mask()
callback in the main chip or GPIO interrupt chip respectively.
Allocate it with bitmap_alloc().
- Isolate the device tree/open firmware GPIO description code out in
its own file properly.
- Isolate the ACPI GPIO description code out in its own file
properly.
- Drop a whole lot of #ifdef:s in the main includes: it does not hurt
to keep the include items around, and we get quicker and clearer
compile failures if the appropriate kernel symbols are not selected
for drivers.
New/deleted drivers:
- New driver for Aspeed SGPIO.
- The KS8695 driver is deleted as the platform gets deleted from
arch/arm in this kernel cycle.
- The Cirrus Logic Madera driver now supports CS47L92 and CS47L15.
- The Freescale MPC8xxx now supports LS1028A and LS1088A.
Driver improvements:
- We pass the GPIO irqchip intialization by directly filling in the
struct instead of using set-up functions (the new way) for Intel
MID, Lynxpoint, Merrifield, XLP, HLWD, Aspeed, ZX, VF610, TQMX86,
MT7621, Zynq and EP93xx.
Out-of-band changes:
- Fix a GPIO header inclusion in Unicore - no response from
maintainer.
- Drop FMC subsystem from MAINTAINERS - was deleted in the GPIO tree
last cycle so let's mop up the shards"

gpiolib-acpi: Move acpi_dev_add_driver_gpios() et al to consumer.h
The API, which belongs to GPIO library, is foreign to ACPI headers. Earlier we moved out I²C out of the latter, and now it's time for acpi_dev_add_driver_gpios() et al. For time being the acpi_gpio_get_irq_resource() and acpi_dev_gpio_irq_get() are left untouched as they need more thought about. Note, it requires uninline acpi_dev_remove_driver_gpios() to keep purity of consumer.h.

gpio: pass lookup and descriptor flags to request_own
When a gpio_chip wants to request a descriptor from itself using gpiochip_request_own_desc() it needs to be able to specify fully how to use the descriptor, notably line inversion semantics. The workaround in the gpiolib.c can be removed and cases (such as SPI CS) where we need at times to request a GPIO with line inversion semantics directly on a chip for workarounds, can be fully supported with this call. Fix up some users of the API that weren't really using the last flag to set up the line as input or output properly but instead just calling direction setting explicitly after requesting the line.

gpiolib: Make use of enum gpio_lookup_flags consistent
The library uses enum gpio_lookup_flags to define the possible characteristics of GPIO pin. Since enumerator listed only individual bits the common use of it is in a form of a bitmask of gpio_lookup_flags GPIO_* values. The more correct type for this is unsigned long. Due to above convert all users to use unsigned long instead of enum gpio_lookup_flags except enumerator definition. While here, make field and parameter descriptions consistent as well.

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.

gpiolib-acpi: Preserve non direction flags when updating gpiod_flags
__acpi_gpio_update_gpiod_flags purpose is to make the gpiod_flags used when requesting a GPIO match the restrictions from the ACPI resource, as stored in acpi_gpio_info.flags. But acpi_gpio_info.flags only contains direction info, and the requester may have passed in special non-direction flags like GPIOD_FLAGS_BIT_NONEXCLUSIVE, which we currently clobber. This commit modifies __acpi_gpio_update_gpiod_flags to preserve these special flags, so that a requested of an ACPI GPIO can e.g. pass GPIOD_FLAGS_BIT_NONEXCLUSIV and have it work as intended.

gpiolib-acpi: Remove unnecessary WARN_ON from acpi_gpiochip_free_interrupts
acpi_gpiochip_alloc_event only continues allocating an event and adding it to the list if gpiochip_request_own_desc does not return an error. So events with an error desc are never placed on the events list and this check is really not necessary.

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.

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"

ACPI / property: Allow multiple property compatible _DSD entries
It is possible to have _DSD entries where the data is compatible with
device properties format but are using different GUID for various reasons.
In addition to that there can be many such _DSD entries for a single device
such as for PCIe root port used to host a Thunderbolt hierarchy:
Scope (\_SB.PCI0.RP21)
{
Name (_DSD, Package () {
ToUUID ("6211e2c0-58a3-4af3-90e1-927a4e0c55a4"),
Package () {
Package () {"HotPlugSupportInD3", 1}
},
ToUUID ("efcc06cc-73ac-4bc3-bff0-76143807c389"),
Package () {
Package () {"ExternalFacingPort", 1},
Package () {"UID", 0 }
}
})
}
More information about these new _DSD entries can be found in:
https://docs.microsoft.com/en-us/windows-hardware/drivers/pci/dsd-for-pcie-root-ports
To make these available for drivers via unified device property APIs,
modify ACPI property core so that it supports multiple _DSD entries
organized in a linked list. We also store GUID of each _DSD entry in struct
acpi_device_properties in case there is need to differentiate between
entries. The supported GUIDs are then listed in prp_guids array.

gpio: Get rid of legacy header
A bunch of core gpiolib files still include the <linux/gpio.h> legacy API header for no good reason. After this only the gpiolib-legacy.c file includes it, which is fine. The sysfs ABI code has a pointless wrapper function around gpio_to_desc() we can just loose. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> |

gpiolib-acpi: Register GpioInt ACPI event handlers from a late_initcall
GpioInt ACPI event handlers may see there IRQ triggered immediately after requesting the IRQ (esp. level triggered ones). This means that they may run before any other (builtin) drivers have had a chance to register their OpRegion handlers, leading to errors like this: [ 1.133274] ACPI Error: No handler for Region [PMOP] ((____ptrval____)) [UserDefinedRegion] (20180531/evregion-132) [ 1.133286] ACPI Error: Region UserDefinedRegion (ID=141) has no handler (20180531/exfldio-265) [ 1.133297] ACPI Error: Method parse/execution failed \_SB.GPO2._L01, AE_NOT_EXIST (20180531/psparse-516) We already defer the manual initial trigger of edge triggered interrupts by running it from a late_initcall handler, this commit replaces this with deferring the entire acpi_gpiochip_request_interrupts() call till then, fixing the problem of some OpRegions not being registered yet. Note that this removes the need to have a list of edge triggered handlers which need to run, since the entire acpi_gpiochip_request_interrupts() call is now delayed, acpi_gpiochip_request_interrupt() can call these directly now.
