2023-03-06gpiolib: split of_mm_gpio_chip out of linux/of_gpio.hArnd Bergmann1-5/+10
This is a rarely used feature that has nothing to do with the client-side of_gpio.h. Split it out with a separate header file and Kconfig option so it can be removed on its own timeline aside from removing the of_gpio consumer interfaces.

2023-01-30gpiolib: Remove unused of_mm_gpiochip_add()Andy Shevchenko1-2/+2
of_mm_gpiochip_add() is unused API, remove it for good. Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Bartosz Golaszewski <[email protected]>
2022-11-07gpio: Add Generic regmap GPIO conversion to the TODO listAndy Shevchenko1-0/+7
It's actually preferable to use Generic regmap GPIO over other simple approaches. Add a TODO item for that. Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Bartosz Golaszewski <[email protected]>
2022-04-19gpio: Update TODO to mention immutable irq_chip structuresMarc Zyngier1-0/+19
5 drivers are converted, a few hundred to go. Definitely worth of a TODO entry, in the hope that someone will notice it and do a bulk update.

2021-01-25gpio: intel-mid: Remove driver for deprecated platformAndy Shevchenko1-1/+1
Intel Moorestown and Medfield are quite old Intel Atom based 32-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 Intel for breaking any of that platforms for years. It seems no real users exists who run more or less fresh kernel on it. The commit 05f4434bc130 ("ASoC: Intel: remove mfld_machine") also in align with this theory. Due to above and to reduce a burden of supporting outdated drivers we remove the support of outdated platforms completely. Moreover this code duplicates gpio-pxa since the IP has been derived from XScale implementation. If anybody wants to resurrect this it has to be part of gpio-pxa.c.

2020-10-28gpio: Retire the explicit gpio irqchip codeLinus Walleij1-49/+0
Now that all gpiolib irqchip users have been over to use the irqchip template, we can finally retire the old code path and leave just one way in to the irqchip: set up the template when registering the gpio_chip. For a while we had two code paths for this which was a bit confusing. This brings this work to a conclusion, there is now one way of doing this.

2020-04-14gpio: Extend TODO to cover code duplication avoidanceAndy Shevchenko1-0/+4
It appears at least two drivers has a lot of duplication code in GPIO subsystem. To avoid adding more and get rid of existing duplication extend TODO. Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Bartosz Golaszewski <[email protected]>

2019-06-14gpio: Add GPIOLIB_IRQCHIP cleanup to TODOLinus Walleij1-0/+40
We now have two APIs for registering GPIOLIB_IRQCHIP, this is not working and creating confusion. Add a TODO item to fix it up. Cc: Thierry Reding <[email protected]> Signed-off-by: Linus Walleij <[email protected]>
2018-11-05gpio: Add global TODO file for GPIOLinus Walleij1-0/+109
With a new subsystem co-maintainer on board it is good to draw up the ongoing changes and future plans for the subsystem, i.e. what is in my head and being worked on long term. What better way is there than simply adding a TODO right in the code and send it out to the mailing list. Cc: Bartosz Golaszewski <[email protected]> Signed-off-by: Linus Walleij <[email protected]>
