The gpiolib-acpi code is becoming more strict and connection-IDs may only be used with devices which have a _DSD with matching IDs in there. Since the soc_button_array ACPI binding is pure index based pass in NULL as connection-ID to avoid the more strict cheks resulting in gpiod_count and gpiod_get_index not returning any gpios.

2017-03-09Input: axp20x-pek - do not register input device on some systemsHans de Goede
On some systems (Intel tablets with axp288 pmic) the powerbutton is also connected to a gpio pin of the SoC, advertised through the "INTCFD9" / "PNP0C40" acpi device. This leads to double reporting of powerbutton events, which is undesirable, so one driver needs to not report input events in this case. Since the soc_button_array driver for the "PNP0C40" acpi device also handles wake from suspend on these tablets and since the axp20x-pel driver requires relative expensive i2c accrsses, it is best for the axp20x-pek driver to not register an input device in this case. Note that this commit leaves the axp20x-driver bound to the device, rather then returning -ENODEV, this is done so that the sysfs attributes it offers are kept around.

Move all input device related initialization into a new axp20x_pek_probe_input_device helper function. This introduces one functional change, the input device is now registered before the sysfs attr get registered. This is not a problem as the sysfs attr are to configure some long press settings (forced poweroff) in the hardware and do not interact with the input_device.

2017-03-08Input: sparse-keymap - use a managed allocation for keymap copyMichał Kępień
Some platform drivers use devm_input_allocate_device() together with sparse_keymap_setup() in their .probe callbacks. While using the former simplifies error handling, using the latter necessitates calling sparse_keymap_free() in the error path and upon module unloading to avoid leaking the copy of the keymap allocated by sparse_keymap_setup(). To help prevent such leaks and enable simpler error handling, make sparse_keymap_setup() use devm_kmemdup() to create the keymap copy so that it gets automatically freed. This works for both managed and non-managed input devices as the keymap is freed after the last reference to the input device is dropped. Note that actions previously taken by sparse_keymap_free(), i.e. taking the input device's mutex and zeroing its keycode and keycodemax fields, are now redundant because the managed keymap will always be freed after the input device is unregistered.

This is a treewide change also updating all users. - Pass a GPIO label down to gpiod_request() from fwnode_get_named_gpiod().

2017-02-22Input: tsc2007 - correctly report pressure and not resistance to user spaceH. Nikolaus Schaller
Previously, tsc2007 would report as ABS_PRESSURE: 0 for no pressure (resistance infinite) high value for soft pressure (high resistance) low value for firm pressure (lower resistance) This does not matter for most applications (e.g. GUI, Menu, Scrolling etc.) where the ABS_PRESSURE is ignored and only BTN_TOUCH is processed to detect screen taps. Only some special graphics applications read the pressure channel and they will be mixed up by this non-monotonic relation. So we fix it to become: 0 for no pressure (resistance infinite) low value for soft pressure (high resistance) high value for firm pressure (lower resistance) While this patch changes the values reported to userspace, ABS_PRESSURE is used rarely by userspace. Most software only relies on BTN_TOUCH (boolean), which is not affected by this patch. Some graphics software makes use of the interface and does not work correctly with the currently used inverted behaviour. Signed-off-by: H.
