* Input: omap-keypad - drop optional GPIO supportLinus Walleij2023-12-131-18/+1
| | | | | | | | | | | | | | | | | | The driver supports passing some GPIO lines for rows and columns through the driver data, but there is no in-kernel user of this. Further the use seems convoluted because the GPIO lines are unused in the driver, then explicitly free:ed when removing it without being requested when probing it, which is assymetric and just a recepie for disaster. Remove the support for these unused GPIOs, if need be support can be reestablished in an organized fashion using GPIO descriptors.

* Input: cap11xx - cache hardware ID registersMark Brown2023-12-121-3/+0
| | | | | | | | | | | | | The cap11xx devices have three hardware identification registers which are currently marked as volatile, preventing caching of those registers. This is not ideal since the registers should never change at runtime, we should be able to cache the value after the first read. Stop marking the registers as volatile, we don't have register defaults specified in the driver so this will result in reading from the hardware on first use.

* Input: gpio-keys - add system suspend support for dedicated wakeirqsTony Lindgren2023-11-301-4/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some SoCs have a separate dedicated wake-up interrupt controller that can be used to wake up the system from deeper idle states. We already support configuring a separate interrupt for a gpio-keys button to be used with a gpio line. However, we are lacking support system suspend for cases where a separate interrupt needs to be used in deeper sleep modes. Because of it's nature, gpio-keys does not know about the runtime PM state of the button gpios, and may have several gpio buttons configured for each gpio-keys device instance. Implementing runtime PM support for gpio-keys does not help, and we cannot use drivers/base/power/wakeirq.c support. We need to implement custom wakeirq support for gpio-keys. For handling a dedicated wakeirq for system suspend, we enable and disable it with gpio_keys_enable_wakeup() and gpio_keys_disable_wakeup() that we already use based on device_may_wakeup(). Some systems may have a dedicated wakeirq that can also be used as the main interrupt, this is already working for gpio-keys. Let's add some wakeirq related comments while at it as the usage with a gpio line and separate interrupt line may not be obvious.

| | | | | | | | | | | | | | | | | | The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
