gpiolib: acpi: Add quirk to ignore EC wakeups on Dell Venue 10 Pro 5055
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.

gpio: sch: Hook into ACPI GPE handler to catch GPIO edge events
Neither the ACPI description on Intel Minnowboard (v1) platform provides the required information to establish a generic handling nor the hardware capable of doing it. According to the data sheet the hardware can generate SCI events. Therefore, we need to hook from the driver into GPE handler of the ACPI subsystem in order to catch and report GPIO-related events. Validated on the Inlel Minnowboard (v1) platform and Intel Galileo Gen 2. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> |

gpio: Add Realtek Otto GPIO support
Realtek MIPS SoCs (platform name Otto) have GPIO controllers with up to 64 GPIOs, divided over two banks. Each bank has a set of registers for 32 GPIOs, with support for edge-triggered interrupts. Each GPIO bank consists of four 8-bit GPIO ports (ABCD and EFGH). Most registers pack one bit per GPIO, except for the IMR register, which packs two bits per GPIO (AB-CD). Although the byte order is currently assumed to have port A..D at offset 0x0..0x3, this has been observed to be reversed on other, Lexra-based, SoCs (e.g. RTL8196E/97D/97F). Interrupt support is disabled for the fallback devicetree-compatible 'realtek,otto-gpio'. This allows for quick support of GPIO banks in which the byte order would be unknown. In this case, the port ordering in the IMR registers may not match the reversed order in the other registers (DCBA, and BA-DC or DC-BA).

This is the bulk of the pin control changes for the v5.13 kernel cycle
Core changes:
- A semantic change to handle pinmux and pinconf in explicit order
while up until now we depended on the semantic order in the
device tree. The device tree is a functional programming
language and does not imply any order, so the right thing is
for the pin control core to provide these semantics.
- Add a new pinmux-select debugfs file which makes it possible to
go in and select functions for a pin manually (iteratively, at
the prompt) for debugging purposes.
- Fixes to gpio regmap handling for a new pin control driver
making use of regmap-gpio.
- Use octal permissions on debugfs files.
New drivers:
- A massive rewrite of the former custom pin control driver for
MIPS Broadcom devices to instead use the pin control subsystem.
New pin control drivers for BCM6345, BCM6328, BCM6358, BCM6362,
BCM6368, BCM63268 and BCM6318 SoC variants are implemented.
- Support for PM8350, PM8350B, PM8350C, PMK8350, PMR735A and
PMR735B in the Qualcomm PMIC GPIO driver. Also the two GPIOs
on PM8008 are supported.
- Support for the Rockchip RK3568/RK3566 pin controller.
- Support for Ingenic JZ4730, JZ4750, JZ4755, JZ4775 and
X2000.
- Support for Mediatek MTK8195.
- Add a new Xilinx ZynqMP pin control driver.
Driver improvements and non-urgent fixes:
- Modularization and improvements of the Rockchip drivers.
- Some new pins added to the description of new Renesas SoCs.
- Clarifications of the GPIO base calculation in the Intel driver.
- Fix the function names for the MPP54 and MPP55 pins in the Armada
CP110 pin controller.
- GPIO wakeup interrupt map for Qualcomm SC7280 and SM8350.
- Support for ACPI probing of the Qualcomm SC8180x.
- Fix interrupt clear status on rockchip
- Fix some missing pins on the Ingenic JZ4770, some semantic
fixes for the behaviour of the Ingenic pin controller.
Add DMIC pins for JZ4780, X1000, X1500 and X1830.
- A slew of janitorial like of_node_put() calls.

ARM: SoC drivers for v5.13
Updates for SoC specific drivers include a few subsystems that
have their own maintainers but send them through the soc tree:
TEE/OP-TEE:
- Add tracepoints around calls to secure world
Memory controller drivers:
- Minor fixes for Renesas, Exynos, Mediatek and Tegra platforms
- Add debug statistics to Tegra20 memory controller

ARM SCMI Firmware:
- Support for modular SCMI protocols and vendor specific extensions
- New SCMI IIO driver
- Per-cpu DVFS
The other driver changes are all from the platform maintainers
directly and reflect the drivers that don't fit into any other
subsystem as well as treewide changes for a particular platform.
SoCFPGA:
- Various cleanups contributed by Krzysztof Kozlowski
Mediatek:
- add MT8183 support to mutex driver
- MMSYS: use per SoC array to describe the possible routing
- add MMSYS support for MT8183 and MT8167

- Add ACPI support for RCPM driver
- Use generic io{read,write} for QE drivers after performance optimized
for PowerPC
- Fix QBMAN probe to cleanup HW states correctly for kexec
- Various cleanup and style fix for QBMAN/QE/GUTS drivers
OMAP:
- Preparation to use devicetree for genpd
- ti-sysc needs iorange check improved when the interconnect target module
has no control registers listed

issues with missing resources and unnecessary deferred probe
- ti-sysc debug option can now detect more devices
- ti-sysc now warns if an old incomplete devicetree data is found as we
now rely on it being complete for am3 and 4
- soc init code needs to check for prcm and prm nodes for omap4/5 and dra7
- omap-prm driver needs to enable autoidle retention support for omap4
- omap5 clocks are missing gpmc and ocmc clock registers
- pci-dra7xx now needs to use builtin_platform_driver instead of using
builtin_platform_driver_probe for deferred probe to work
Raspberry Pi:
- Fix-up all RPi firmware drivers so as for unbind to happen in an
orderly fashion
- Support for RPi's PoE hat PWM bus
Qualcomm
- Improved detection for SCM calling conventions

gpio: omap: Save and restore sysconfig
As we are using cpu_pm to save and restore context, we must also save and
restore the GPIO sysconfig register. This is needed because we are not
calling PM runtime functions at all with cpu_pm.
We need to save the sysconfig on idle as it's value can get reconfigured by
PM runtime and can be different from the init time value. Device specific
flags like "ti,no-idle-on-init" can affect the init value.

gpio: Support ROHM BD71815 GPOs
Support GPO(s) found from ROHM BD71815 power management IC. The IC has two GPO pins but only one is properly documented in the data-sheet. The driver exposes by default only the documented GPO. The second GPO is connected to E5 pin and is marked as GND in the data-sheet. Control for this undocumented pin can be enabled using a special DT property. This driver is derived from work by Peter Yang <yanglsh@embest-tech.com> although not so much of the original is left.

gpiolib: Reuse device's fwnode to create IRQ domain
When IRQ domain is created for an ACPI case, the name of it becomes unknown-%d since for now it utilizes of_node member only and doesn't consider fwnode case. Convert IRQ domain creation code to utilize fwnode instead. Before/After the change on Intel Galileo Gen 2 with two GPIO (IRQ) controllers: unknown-1 ==> \_SB.PCI0.GIP0.GPO unknown-2 ==> \_SB.NIO3 Due to the nature of this change we may also deduplicate the WARN():s because in either case (DT or ACPI) the fwnode will be set correctly and %pfw is an equivalent to what the current code prints as a prefix.

gpiolib: Read "gpio-line-names" from a firmware node
On STM32MP1, the GPIO banks are subnodes of pin-controller@50002000,
see arch/arm/boot/dts/stm32mp151.dtsi. The driver for
pin-controller@50002000 is in drivers/pinctrl/stm32/pinctrl-stm32.c
and iterates over all of its DT subnodes when registering each GPIO
bank gpiochip. Each gpiochip has:
- gpio_chip.parent = dev,
where dev is the device node of the pin controller
- gpio_chip.of_node = np,
which is the OF node of the GPIO bank
Therefore, dev_fwnode(chip->parent) != of_fwnode_handle(chip.of_node),
i.e. pin-controller@50002000 != pin-controller@50002000/gpio@5000*000.
The original code behaved correctly, as it extracted the "gpio-line-names"
from of_fwnode_handle(chip.of_node) = pin-controller@50002000/gpio@5000*000.
To achieve the same behaviour, read property from the firmware node.

gpio: fix gpio-device list corruption
Make sure to hold the gpio_lock when removing the gpio device from the
gpio_devices list (when dropping the last reference) to avoid corrupting
the list when there are concurrent accesses.

gpio: fix NULL-deref-on-deregistration regression
Fix a NULL-pointer deference when deregistering the gpio character
device that was introduced by the recent stub-driver hack. When the new
"driver" is unbound as part of deregistration, driver core clears the
driver-data pointer which is used to retrieve the struct gpio_device in
its release callback.
Fix this by using container_of() in the release callback as should have
been done all along.
Fixes:

Driver core / debugfs update for 5.12-rc1
Here is the "big" driver core and debugfs update for 5.12-rc1
This set of driver core patches caused a bunch of problems in linux-next
for the past few weeks, when Saravana tried to set fw_devlink=on as the
default functionality. This caused a number of systems to stop booting,
and lots of bugs were fixed in this area for almost all of the reported
systems, but this option is not ready to be turned on just yet for the
default operation based on this testing, so I've reverted that change at
the very end so we don't have to worry about regressions in 5.12. We
will try to turn this on for 5.13 if testing goes better over the next
few months.
Other than the fixes caused by the fw_devlink testing in here, there's
not much more:
- debugfs fixes for invalid input into debugfs_lookup()
- kerneldoc cleanups
- warn message if platform drivers return an error on their
remove callback (a futile effort, but good to catch).
All of these have been in linux-next for a while now, and the
regressions have gone away with the revert of the fw_devlink change.

gpio: pcf857x: Fix missing first interrupt
If no n_latch value will be provided at driver probe then all pins will
be used as an input:
gpio->out = ~n_latch;
In that case initial state for all pins is "one":
gpio->status = gpio->out;
So if pcf857x IRQ happens with change pin value from "zero" to "one"
then we miss it, because of "one" from IRQ and "one" from initial state
leaves corresponding pin unchanged:
change = (gpio->status ^ status) & gpio->irq_enabled;
The right solution will be to read actual state at driver probe.
