The adp5585 MFD driver was introduced in 6.11 adding support for gpio and PWM. However, the gpio part of it was already supported as part of the keyboard driver: https://elixir.bootlin.com/linux/v6.14-rc6/source/drivers/input/keyboard/adp5589-keys.c#L532 On top of that it also overlapped with my refactoring of the above driver [1] to drop usage of platform data and use FW properties instead. Now, it actually makes sense for this device to be supported under MFD and since the "legacy" input device depends on platform data that is not defined anywhere the plan in this series is to add support for the keyboard and adp5589 devices as part of the MFD driver. Once the MFD driver supports all that's supported in the Input one, we drop it... For DT Maintainers: The compatible for adp5589 is part of trivial devices. To me, it makes sense to remove it in the patch where we drop the driver but doing so would result in a warning when adding the same compatible for the MFD bindings. Hence, I remove it in that patch. Is that ok? Uwe: In my eval board, I could see that reading the GPIO value (when configured as input) does not work when OSC_EN is not set. Therefore, commit ("pwm: adp5585: don't control OSC_EN in the pwm driver") could very well have a Fixes tag. However I'm not 100% sure it's a real issue or something special to my eval board. It would be nice if Laurent or Liu could test the PWM bits or even check that the above is also an issue for their platform.
