git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux Pull gpio updates from Bartosz Golaszewski: "We have two new drivers, some improvements to the core code, lots of different updates to existing GPIO drivers and some dt-bindings on top. There's nothing controversial in here and almost everything has been in next for more than a week (95% a lot longer than this). The only thing that has spent less time in next is a new driver so no risk of regressions. The single merge pulls in changes that remove all usage of global GPIO numbers from arch/arm/mach-omap. Core GPIO library: - remove unused symbols - don't spam the kernel log with messages about hogs - remove old sysfs API cruft - improve handling of GPIO masks New drivers: - add a driver for the BlueField-3 GPIO controller - add GPIO support for the TPS65219 PMIC Driver improvements: - extend the gpio-aggregator driver to support ramp-up/ramp-down delay - remove unnecessary CONFIG_OF guards from gpio-aggregator - readability improvements in gpio-tangier - switch i2c drivers back to using probe() now that it's been converted in the i2c subsystem to not taking the id parameter - remove unused inclusions of of_gpio.h in several drivers - make pm ops static in gpio-davinci and fix a comment - use more devres in drivers to shrink and simplify the code - add missing include in gpio-sa1100 - add HAS_IOPORT KConfig dependency where needed - add permissions checks before accessing pins in gpio-tegra186 - convert the gpio-zynq driver to using immutable irqchips - preserve output settings set by the bootloader in gpio-mpc8xxx Selftests: - tweak the variable naming in script tests Device tree updates: - convert gpio-mmio and gpio-stmpe to YAML - add parsing of GPIO hogs to gpio-vf610 - add bindings for the Cirrus EP93xx GPIO controller - add gpio-line-names property to the gpio-pca9570 bindings - extend the binding for x-powers,axp209 with another block" * tag 'gpio-updates-for-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (58 commits) of: unittest: drop assertions for GPIO hog messages gpiolib: Drop unused domain_ops memeber of GPIO IRQ chip gpio: synq: remove unused zynq_gpio_irq_reqres/zynq_gpio_irq_relres dt-bindings: gpio: gpio-vf610: Add parsing of hogs gpio: lpc18xx: Remove unused of_gpio.h inclusion gpio: xra1403: Remove unused of_gpio.h inclusion gpio: mpc8xxx: Remove unused of_gpio.h inclusion dt-bindings: gpio: Add Cirrus EP93xx gpio: mpc8xxx: latch GPIOs state on module load when configured as output selftests: gpio: gpio-sim: Use same variable name for sysfs pathname gpio: mlxbf3: Add gpio driver support gpio: delay: Remove duplicative functionality gpio: aggregator: Set up a parser of delay line parameters gpio: aggregator: Support delay for setting up individual GPIOs gpio: aggregator: Remove CONFIG_OF and of_match_ptr() protections dt-bindings: gpio: pca9570: add gpio-line-names property gpiolib: remove unused gpio_cansleep() gpio: tps65219: add GPIO support for TPS65219 PMIC gpio: zynq: fix zynqmp_gpio not an immutable chip warning gpio: davinci: make davinci_gpio_dev_pm_ops static ...
2023-06-16gpio: mlxbf3: Add gpio driver supportAsmaa Mnebhi
Add support for the BlueField-3 SoC GPIO driver. This driver configures and handles GPIO interrupts. It also enables a user to manipulate certain GPIO pins via libgpiod tools or other kernel drivers. The usables pins are defined via the "gpio-reserved-ranges" property.

2023-06-13gpio: tps65219: add GPIO support for TPS65219 PMICJerome Neanne
Add support for TPS65219 PMICs GPIO interface. 3 GPIO pins: - GPIO0 only is IO but input mode reserved for MULTI_DEVICE_ENABLE usage. - GPIO1 and GPIO2 are Output only and referred as GPO1 and GPO2 in spec. GPIO0 is statically configured as input or output prior to Linux boot. it is used for MULTI_DEVICE_ENABLE function. This setting is statically configured by NVM. GPIO0 can't be used as a generic GPIO (specification Table 8-34). It's either a GPO when MULTI_DEVICE_EN=0 or a GPI when MULTI_DEVICE_EN=1. Datasheet describes specific usage for non standard GPIO.

In fact the device with chip id 0xD283 is called NCT6126D, and that is the chip id the Nuvoton code was written for. Correct that name to avoid confusion, because a NCT6116D in fact exists as well but has another chip id, and is currently not supported. The look at the spec also revealed that GPIO group7 in fact has 8 pins, so correct the pin count in that group as well.

2023-03-06gpiolib: coldfire: remove custom asm/gpio.hArnd Bergmann
Now that coldfire is the only user of a custom asm/gpio.h, it seems better to remove this as well, and have the same interface everywhere. For the gpio_get_value()/gpio_set_value()/gpio_to_irq(), gpio_cansleep() functions, the custom version is only a micro-optimization to inline the function for constant GPIO numbers. However, in the coldfire defconfigs, I was unable to find a single instance where this micro-optimization was even used, and according to Geert the only user appears to be the QSPI chip that is disabled everywhere. The custom gpio_request_one() function is even less useful, as it is guarded by an #ifdef that is never true.

REGMAP is a hidden (not user visible) symbol. Users cannot set it directly thru "make *config", so drivers should select it instead of depending on it if they need it. Consistently using "select" or "depends on" can also help reduce Kconfig circular dependency issues. Therefore, change the use of "depends on REGMAP" to "select REGMAP".

The regmap API supports IO port accessors so we can take advantage of regmap abstractions rather than handling access to the device registers directly in the driver. By leveraging the gpio-regmap API, the i8255 library is reduced to simply a devm_i8255_regmap_register() function, a configuration structure struct i8255_regmap_config, and a helper macro i8255_volatile_regmap_range() provided to simplify volatile PPI register hinting for the regmap. Legacy functions and code will be removed once all consumers have migrated to the new i8255 library interface.

The regmap API supports IO port accessors so we can take advantage of regmap abstractions rather than handling access to the device registers directly in the driver. Despite the underlying interface being based on i8255, it is simpler to use the gpio-regmap API directly because the 104-IDI-48 device features only input signals. Therefore, the dependence on the i8255 GPIO library is removed in this patch.

The regmap API supports IO port accessors so we can take advantage of regmap abstractions rather than handling access to the device registers directly in the driver. For the 104-dio-48e we have the following IRQ registers (0xB and 0xF): Base Address +B (Write): Enable Interrupt Base Address +B (Read): Disable Interrupt Base Address +F (Read/Write): Clear Interrupt Any write to 0xB will enable interrupts, while any read will disable interrupts. Interrupts are cleared by a write to 0xF. There's no IRQ status register, so software has to assume that if an interrupt is raised then it was for the 104-DIO-48E device.

Exposes consumer library functions providing support for interfaces compatible with the venerable Intel 8255 Programmable Peripheral Interface (PPI). The Intel 8255 PPI first appeared in the early 1970s, initially for the Intel 8080 and later appearing in the original IBM-PC. The popularity of the original Intel 8255 chip led to many subsequent variants and clones of the interface in various chips and integrated circuits. Although still popular, interfaces compatible with the Intel 8255 PPI are nowdays typically found embedded in larger VLSI processing chips and FPGA components rather than as discrete ICs. A CONFIG_GPIO_I8255 Kconfig option is introduced by this patch. Modules wanting access to these i8255 library functions should select this Kconfig option, and import the I8255 symbol namespace.
