gpio: vf610: drop the SOC_VF610 dependency for GPIO_VF610

2022-05-02T12:12:30+00:00

i.MX7ULP, i.MX8 and i.MX9 use this driver, so drop the SOC_VF610 dependcy to make the driver could be built for i.MX platform. Signed-off-by: Peng Fan Signed-off-by: Bartosz Golaszewski

irq/gpio: ixp4xx: Drop boardfile probe path

2022-04-25T18:53:18+00:00

The boardfiles for IXP4xx have been deleted. Delete all the quirks and code dealing with that boot path and rely solely on device tree boot. Fix some missing static keywords that the kernel test robot was complaining about while we're at it.

gpio: ixp4xx: Detect special machines by compatible

2022-04-18T19:42:05+00:00

There are some special clock amendments for two machines formerly detected by their machine_is() boardfile macro. They are now migrated to device tree so use of_machine_is_compatible() instead. Signed-off-by: Linus Walleij Signed-off-by: Bartosz Golaszewski

intel-gpio for v5.18-1 * Set IRQ bus token in gpio-crystalcove to avoid debugfs error * Check return value of kstrdup() in gpio-merrifield to error out earlier * Clean up couple of drivers from unneeded of_node usage * Allow gpio-tps68470 to be built as module to reduce memory foot print

gpio: Add Delta TN48M CPLD GPIO driver

2022-02-25T08:59:35+00:00

Delta TN48M switch has an onboard Lattice CPLD that is used as a GPIO expander. The CPLD provides 12 pins in total on the TN48M, but on more advanced switch models it provides up to 192 pins, so the driver is extendable to support more switches.

gpio: tps68470: Allow building as module

2022-01-24T15:23:15+00:00

The gpio-tps68470 driver binds to a tps68470-gpio platform-device which itself gets instantiated by a special MFD driver from drivers/platform/x86/intel/int3472/tps68470.c This MFD driver itself can be built as a module, so it makes no sense to force the gpio-tps68470 driver to always be built-in.

Pull gpio updates from Bartosz Golaszewski: "The gpio-sim module is back, this time without any changes to configfs. This results in a less elegant user-space interface but I never got any follow-up on the committable items and didn't want to delay this module for several more months. Other than that we have support for several new models and some support going away. We started working on converting GPIO drivers to using fwnode exclusively in order to limit references to OF symbols to gpiolib-of.c exclusively. We also have regular tweaks and improvements all over the place. Summary: - new testing module: gpio-sim that is scheduled to replace gpio-mockup - initial changes aiming at converting all GPIO drivers to using the fwnode interface and limiting any references to OF symbols to gpiolib-of.c - add support for Tegra234 and Tegra241 to gpio-tegra186 - add support for new models (SSD201 and SSD202D) to gpio-msc313 - add basic support for interrupts to gpio-aggregator - add support for AMDIF031 HID device to gpio-amdpt - drop support for unused platforms in gpio-xlp - cleanup leftovers from the removal of the legacy Samsung Exynos GPIO driver - use raw spinlocks in gpio-aspeed and gpio-aspeed-sgpio to make PREEMPT_RT happy - generalize the common 'ngpios' device property by reading it in the core gpiolib code so that we can remove duplicate reads from drivers - allow line names from device properties to override names set by drivers - code shrink in gpiod_add_lookup_table() - add new model to the DT bindings for gpio-vf610 - convert DT bindings for tegra devices to YAML - improvements to interrupt handling in gpio-rcar and gpio-rockchip - updates to intel drivers from Andy (details in the merge commit) - some minor tweaks, improvements and coding-style fixes all around the subsystem" * tag 'gpio-updates-for-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (59 commits) gpio: rcar: Propagate errors from devm_request_irq() gpio: rcar: Use platform_get_irq() to get the interrupt gpio: ts5500: Use platform_get_irq() to get the interrupt gpio: dwapb: Switch to use fwnode instead of of_node gpiolib: acpi: make fwnode take precedence in struct gpio_chip dt-bindings: gpio: samsung: drop unused bindings gpio: max3191x: Use bitmap_free() to free bitmap gpio: regmap: Switch to use fwnode instead of of_node gpio: tegra186: Add support for Tegra241 dt-bindings: gpio: Add Tegra241 support gpio: brcmstb: Use local variable to access OF node gpio: Remove unused local OF node pointers gpio: sim: add missing fwnode_handle_put() in gpio_sim_probe() gpio: msc313: Add support for SSD201 and SSD202D gpio: msc313: Code clean ups dt-bindings: gpio: msc313: Add offsets for ssd20xd dt-bindings: gpio: msc313: Add compatible for ssd20xd gpio: sim: fix uninitialized ret variable gpio: Propagate firmware node from a parent device gpio: Setup parent device and get rid of unnecessary of_node assignment ...
