2025-07-23gpio: cadence: Remove duplicated include in gpio-cadence.cYang Li
The header files linux/gpio/driver.h is included twice in gpio-cadence.c, so one inclusion of each can be removed.

2025-07-23gpio: tps65219: Add support for TI TPS65214 PMICShree Ramamoorthy
Add support for the TI TPS65214 PMIC with the addition of an id_table, separate TPS65214 template_chip, and device-specific _change_direction functions. - Use platform_get_device_id() to assign dev-specific information. - Use different change_direction() functions since TPS65214's GPIO configuration bits are changeable during device operation through bit GPIO_CONFIG in GENERAL_CONFIG register. - Remove MODULE_ALIAS since it is now generated by MODULE_DEVICE_TABLE.

2025-07-23gpio: tps65219: Update _IDX & _OFFSET macro prefixShree Ramamoorthy
TPS65215 and TPS65219 are overlapping PMIC devices. While their regulator features differe, the GPIO features are the same. In the TPS65219 MFD driver, the 2 PMICs share the same "tps65219-gpio" compatible string to limit support for TPS65215 in this GPIO driver to comments. The TPS6521X_GPIO0_IDX and TPS6521X_GPIO0_OFFSET macro name prefixes are updated to indicate these macros apply to both PMICs.

2025-07-19gpio: sysfs: Fix an end of loop test in gpiod_unexport()Dan Carpenter
The test for "if (!desc_data)" does not work correctly because the list iterator in a list_for_each_entry() loop is always non-NULL. If we don't exit via a break, then it points to invalid memory. Instead, use a tmp variable for the list iterator and only set the "desc_data" when we have found a match.

Many simple GPIO controllers without interrupt capability have the same schema other than their compatible value. Combine all these bindings into a single schema. The criteria to be included here is must use 2 cells, have no interrupt capability, have 0 or 1 "reg" entries, and have no other resources (like clocks). Note that "ngpios" is now allowed in some cases it wasn't before and constraints on it have been dropped.

2025-07-16gpio: sysfs: don't use driver data in sysfs callbacks for line attributesBartosz Golaszewski
Currently each exported GPIO is represented in sysfs as a separate class device. This allows us to simply use dev_get_drvdata() to retrieve the pointer passed to device_create_with_groups() from sysfs ops callbacks. However, we're preparing to add a parallel set of per-line sysfs attributes that will live inside the associated gpiochip group. They are not registered as class devices and so have the parent device passed as argument to their callbacks (the GPIO chip class device). Put the attribute structs inside the GPIO descriptor data and dereference the relevant ones using container_of() in the callbacks. This way, we'll be able to reuse the same code for both the legacy and new GPIO attributes.

2025-07-16gpio: sysfs: add a parallel class device for each GPIO chip using device IDsBartosz Golaszewski
In order to enable moving away from the global GPIO numberspace-based exporting of lines over sysfs: add a parallel, per-chip entry under /sys/class/gpio/ for every registered GPIO chip, denoted by device ID in the file name and not its base GPIO number. Compared to the existing chip group: it does not contain the "base" attribute as the goal of this change is to not refer to GPIOs by their global number from user-space anymore. It also contains its own, per-chip export/unexport attribute pair which allow to export lines by their hardware offset within the chip. Caveat #1: the new device cannot be a link to (or be linked to by) the existing "gpiochip<BASE>" entry as we cannot create links in /sys/class/xyz/. Caveat #2: the new entry cannot be named "gpiochipX" as it could conflict with devices whose base is statically defined to a low number. Let's go with "chipX" instead.

2025-07-15gpio: xtensa: remove unneeded .set() callbackBartosz Golaszewski
GPIO core deals just fine with input-only controllers not implementing the .set() callback. Remove the unneeded dummy implementation.

2025-07-15gpio: xlp: drop unneeded ngpio checksBartosz Golaszewski
GPIO core already makes sure that offsets higher than the number of GPIOs are never passed to controller callbacks. We can remove the unnecessary check.
