gpiolib: split of_mm_gpio_chip out of linux/of_gpio.h

2023-03-06T10:33:01+00:00

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.

gpio: Add Generic regmap GPIO conversion to the TODO list

2022-11-07T08:42:32+00:00

It's actually preferable to use Generic regmap GPIO over other simple approaches. Add a TODO item for that. Signed-off-by: Andy Shevchenko Signed-off-by: Bartosz Golaszewski

gpio: Update TODO to mention immutable irq_chip structures

2022-04-19T14:22:26+00:00

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.

gpio: intel-mid: Remove driver for deprecated platform

2021-01-25T18:05:31+00:00

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 Due to above and to reduce a burden of supporting outdated drivers we remove the support of outdated platforms completely.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.

gpio: Add TODO item for debugfs interface

2020-12-05T23:13:17+00:00

The idea to create a debugfs to replace the aging and dangerous sysfs ABI for hacking and tinkering came up on the list. Signed-off-by: Linus Walleij Reviewed-by: Geert Uytterhoeven Cc: Geert Uytterhoeven Link: https://lore.kernel.org/r/20201204083533.65830-1-linus.walleij@linaro.org

gpio: Retire the explicit gpio irqchip code

2020-10-28T14:50:06+00:00

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.
