From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org> gpiod_toggle_active_low() is a badly designed API that should have never been used elsewhere then in the MMC code.

I intended to reply to that thread to say that I liked that approach, but I don't remember if I actually did reply. I wonder what made you abandon the new function to directly set the active-low flag on a gpio_desc? For the int3472 code that would work pretty well and it would be much cleaner then the temp gpio-lookup approach.

Under one of the other patches Linus W stated that first: adding the ability for consumers to toggle the polarity was added to handle the MMC slot quirk, then it was used unknowingly to GPIO maintainers in other places (including this driver). I then acknowledged the fact that it should have never existed in the first place as this is HW description and should be defined in ACPI, DT or lookup flags. I'm not sure why this information needs to be hard-coded in the driver in int3472_get_func_and_polarity() but maybe it could be pulled into gpiolib-acpi.c with other quirks? Bart

The problem is that for camera sensors Intel uses this special INT3472 ACPI device with a custom _DSM to list GPIOs, with the _DSM returning an u32 and one of the bits in the u32 is the polarity. We really do not want to deal with this Intel camera team hack inside gpiolib-acpi and I can understand why you and Linus W want to get rid of functions which allow drivers to meddle with a gpio_desc's active-low flag. So using a temporary gpio-lookup in the int3472 code as you are proposing is the best (least bad) thing to do here then. I'll try to make some time to test this sometime the coming days. Other then the discussion we just had is there any specific reason why this should be considered a RFC / why this would not be ready for merging? (I still need to review these, but lets assume that goes well) Regards, Hans

I missed that 4/4 removes acpi_get_and_request_gpiod(), so I guess that this is not just only about removing gpiod_toggle_active_low() but also about removing gpiod_toggle_active_low() ?

I have just send out a v3 to address Andy's remark about me somehow resetting the authorship to me on 2 patches from Bartosz. While working on this I noticed (and fixed) a bug in: [RFT PATCH 1/4] platform/x86: int3472: provide a helper for getting GPIOs from lookups https://lore.kernel.org/all/20230926145943.42814-2-brgl@bgdev.pl/ struct gpiod_lookup_table *lookup __free(kfree) = kzalloc(struct_size(lookup, table, 1), GFP_KERNEL); You are allocating an entry for the temp lookup, but the gpiolib core expects lookup tables to be terminated with an entry lookup, so this should alloc space for 2 entries: struct gpiod_lookup_table *lookup __free(kfree) = kzalloc(struct_size(lookup, table, 2), GFP_KERNEL); Despite this already being fixed now I wanted to explicitly point this out in case you have used the same construct elsewhere during your recent gpiolib cleanup efforts ? As for your request for a tag for the 4st 4 patches for you to merge into gpiolib. I'll go and work work on that. I need to coordinate this with Ilpo, with whom I now co-maintain pdx86 .

Add a new skl_int3472_fill_gpiod_lookup() helper.
This is a preparation patch for removing usage of the deprecated
gpiod_toggle_active_low() and acpi_get_and_request_gpiod() functions.

2.41.0
Add a new skl_int3472_gpiod_get_from_temp_lookup() helper.
This is a preparation patch for removing usage of the deprecated
gpiod_toggle_active_low() and acpi_get_and_request_gpiod() functions.

Yes you are correct, I'll prepare a new version of the series with this fixed. Regards, hans
Use the new skl_int3472_gpiod_get_from_temp_lookup() helper to get
a gpio to pass to register_gpio_clock(), skl_int3472_register_regulator()
and skl_int3472_register_pled().
This removes all use of the deprecated gpiod_toggle_active_low() and
acpi_get_and_request_gpiod() functions.
