Input: soc_button_array - debounce the buttons

2017-01-21T19:46:52Z

The soc_button_array driver was initializing (kzalloc) the debounce_interval value to 0, leading to no debouncing at all, while the buttons are simple mechanical switches. This commit sets debounce_interval to 50ms to avoid spurious button press reports both on press and release of the button. Note 50ms may seem like a lot but soc_button_array is typically used with cheap tablets, with not so great buttons. I tried 10ms on my tablet and it is not enough, where as 50ms works well.

Input: soc_button_array - use 'dev' instead of dereferencing it

2017-01-18T19:49:16Z

Use local variable 'dev' instead of dereferencing it several times. Signed-off-by: Guenter Roeck Signed-off-by: Dmitry Torokhov

Input: soc_button_array - bail out earlier if gpiod_count is zero

2016-11-25T19:39:50Z

The PNP0C40 device of the Surface 3 doesn't have any GPIO attached to it. Instead of trying to access the GPIO, request the count beforehand and bail out if it is null or if an error is returned. Signed-off-by: Benjamin Tissoires Signed-off-by: Dmitry Torokhov

Input: soc_button_array - use gpio_is_valid()

2016-11-25T19:39:49Z

gpio_keys will later use gpio_is_valid(). To match the actual behavior, we should use it here too. Signed-off-by: Benjamin Tissoires Signed-off-by: Dmitry Torokhov

Input: soc_button_array - remove duplicated include

Input: soc_button_array - use "Windows" key for "Home"

2015-02-10T23:45:00Z

KEY_HOME is the key to go back to the beginning of the line, not the key to get into an overview mode, as Windows does. GNOME can already make use of the Windows key on multiple form factors, and other desktop environments can use it depending on the form factor. Using "Windows" as the emitted key also means that the keycode sent out matches the symbol on the key itself. So switch KEY_HOME to KEY_LEFTMETA ("Windows" key).

Merge branch 'platform/remove_owner' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux into driver-core-next

2014-11-04T03:53:56Z

Remove all .owner fields from platform drivers

Input: soc_button_array - update calls to gpiod_get*()

2014-10-24T21:54:44Z

Add the new flags argument to calls of (devm_)gpiod_get*(). Currently both forms (with or without the flags argument) are valid thanks to transitional macros in . These macros will be removed once all consumers are updated and the flags argument will become compulsory. Signed-off-by: Alexandre Courbot Signed-off-by: Dmitry Torokhov

input: misc: drop owner assignment from platform_drivers

2014-10-20T14:20:40Z

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

Input: soc_button_array - convert to platform bus

2014-09-24T23:27:24Z

ACPI device enumeration mechanism changed a lot since 3.16-rc1. ACPI device objects with _HID will be enumerated to platform bus by default. For the existing PNP drivers that probe the PNPACPI devices, the device ids are listed explicitly in drivers/acpi/acpi_pnp.c. But ACPI folks will continue their effort on shrinking this id list by converting the PNP drivers to platform drivers, for the devices that don't belong to PNP bus in nature.
