2de1cf17 - gpio: TODO: track the removal of regulator-related workarounds

Tue, 01 Apr 2025 12:46:45 +0000

gpio: TODO: track the removal of regulator-related workaroundsThe GPIOD_FLAGS_BIT_NONEXCLUSIVE flag and devm_gpiod_unhinge() functionshould be replaced with a better solution. The pwrseq subsystem is a goodcandidate. GPIOs themselves should remain a unique resource. Add a taskfor tracking the removal of these deprecated symbols.Acked-by: Linus Walleij Link: https://lore.kernel.org/r/20250401-gpio-todo-remove-nonexclusive-v2-4-7c1380797b0d@linaro.orgSigned-off-by: Bartosz Golaszewski List of files: /linux-6.15/drivers/gpio/TODO

af54a2fb - gpio: TODO: add an item to track reworking the sysfs interface

Fri, 21 Mar 2025 15:49:38 +0000

gpio: TODO: add an item to track reworking the sysfs interfaceIt seems there really exists the need for a simple sysfs interface thatcan be easily used from minimal initramfs images that don't contain muchmore than busybox. However the current interface poses a challenge tothe removal of global GPIO numberspace. Add an item that tracksextending the existing ABI with a per-chip export/unexport attributepair.Reviewed-by: Linus Walleij Link: https://lore.kernel.org/r/20250321-gpio-todo-updates-v1-6-7b38f07110ee@linaro.orgSigned-off-by: Bartosz Golaszewski List of files: /linux-6.15/drivers/gpio/TODO

c36420dc - gpio: TODO: remove the pinctrl integration task

Fri, 21 Mar 2025 15:49:35 +0000

gpio: TODO: remove the pinctrl integration taskWhile there are surely some arguments in favor of integrating the GPIOand pinctrl subsystems into one, I believe this is not the rightapproach.The GPIO subsystem uses intricate locking with SRCU to handle the factthat both consumers and providers may run in different contexts.Pin-controller drivers are always meant to run in process context. Thisalone is a huge obstacle to any attempt at integration as evident bymany problems we already encountered during the hotplug rework.The current glue code is pretty minimal and for most part already allowsGPIO controllers to query pinctrl about the information they need.I suggest to drop this task and keep the subsystems separate even ifmany pin-controllers implement GPIO functionality in addition to pinfunctions.Reviewed-by: Linus Walleij Link: https://lore.kernel.org/r/20250321-gpio-todo-updates-v1-3-7b38f07110ee@linaro.orgSigned-off-by: Bartosz Golaszewski List of files: /linux-6.15/drivers/gpio/TODO

Fri, 21 Mar 2025 15:49:33 +0000

gpio: TODO: remove the item about the new debugfs interfaceThe consensus among core GPIO stakeholders seems to be that a newdebugfs interface will only increase maintenance burden and will failto attract users that care about long-term stability of the ABI[1].Let's not go this way and not add a fourth user-facing interface to theGPIO subsystem.[1] https://lore.kernel.org/all/9d3f1ca4-d865-45af-9032-c38cacc7fe93@pengutronix.de/Reviewed-by: Linus Walleij Link: https://lore.kernel.org/r/20250321-gpio-todo-updates-v1-1-7b38f07110ee@linaro.orgSigned-off-by: Bartosz Golaszewski List of files: /linux-6.15/drivers/gpio/TODO

944dcbe8 - gpio: intel-mid: Remove driver for deprecated platform

Fri, 22 Nov 2019 14:57:30 +0000

gpio: intel-mid: Remove driver for deprecated platformIntel Moorestown and Medfield are quite old Intel Atom based32-bit platforms, which were in limited use in some Android phones,tablets and consumer electronics more than eight years ago.There are no bugs or problems ever reported outside from Intelfor breaking any of that platforms for years. It seems no realusers exists who run more or less fresh kernel on it. The commit05f4434bc130 ("ASoC: Intel: remove mfld_machine") also in alignwith this theory.Due to above and to reduce a burden of supporting outdated driverswe remove the support of outdated platforms completely.Moreover this code duplicates gpio-pxa since the IP has been derivedfrom XScale implementation. If anybody wants to resurrect thisit has to be part of gpio-pxa.c.Signed-off-by: Andy Shevchenko Acked-by: Linus Walleij List of files: /linux-6.15/drivers/gpio/TODO

gpio: Retire the explicit gpio irqchip codeNow that all gpiolib irqchip users have been over to usethe irqchip template, we can finally retire the old codepath and leave just one way in to the irqchip: set up thetemplate when registering the gpio_chip.
