2025-08-07treewide: rename GPIO set callbacks back to their original namesBartosz Golaszewski
The conversion of all GPIO drivers to using the .set_rv() and .set_multiple_rv() callbacks from struct gpio_chip (which - unlike their predecessors - return an integer and allow the controller drivers to indicate failures to users) is now complete and the legacy ones have been removed. Rename the new callbacks back to their original names in one sweeping change. Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

2025-07-27Input: atkbd - correctly map F13 - F24Werner Sembach
Currently only F23 is correctly mapped for PS/2 keyboards. According to this table: https://download.microsoft.com/download/1/6/1/161ba512-40e2-4cc9-843a-923143f3456c/translate.pdf - F24 and Zenkaku/Hankaku share the same scancode, but since in real world Zenkaku/Hankaku keys seem to just use the tilde scancode, this patch binds the scancode to F24. Note that on userspace side the KEY_ZENKAKUHANKAKU keycode is currently not bound in xkeyboard-config, so it is (mostly*) unused anyway. * Qt on Wayland and therefore KDE on Wayland can see the keypress anyway for some reason and it is actually used in a touchpad toggle shortcut, but this is currently being fixed in both KDE and xkeyboard-config to make this less weird, so it could directly be fixed to correctly handle the F24 keypress instead. - The scancodes for F13-F22 are currently unmapped so there will probably be no harm in mapping them. This would also fix the issue that some of these keys can't be mapped as the target from userspace using the `setkeycodes` command.

Moreover, recently, with commit 480a8ad683d7 ("mfd: adp5585: Add Analog Devices ADP5585 core support") we overlapped support for the adp5585 device (gpiochip part of it) but since it actually makes sense for the device to be supported under MFD, we can complement it and add the keymap support for it (properly based on FW properties).

2025-01-20Input: atkbd - map F23 key to support default copilot shortcutMark Pearson
Microsoft defined Meta+Shift+F23 as the Copilot shortcut instead of a dedicated keycode, and multiple vendors have their keyboards emit this sequence in response to users pressing a dedicated "Copilot" key. Unfortunately the default keymap table in atkbd does not map scancode 0x6e (F23) and so the key combination does not work even if userspace is ready to handle it. Because this behavior is common between multiple vendors and the scancode is currently unused map 0x6e to keycode 193 (KEY_F23) so that key sequence is generated properly.

2025-01-14Input: Use str_enable_disable-like helpersKrzysztof Kozlowski
Replace ternary (condition ? "enable" : "disable") syntax with helpers from string_choices.h because: 1. Simple function call with one argument is easier to read. Ternary operator has three arguments and with wrapping might lead to quite long code. 2. Is slightly shorter thus also easier to read. 3. It brings uniformity in the text - same string. 4. Allows deduping by the linker, which results in a smaller binary file.
