Commit af79ce47 authored by Linus Torvalds's avatar Linus Torvalds

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input subsystem updates from Dmitry Torokhov:

 - updated support for Synaptics RMI4 devices, including support for
   SMBus controllers, firmware update support, sensor tuning, and PS/2
   guest support

 - ALPS driver now supports tracksticks on SS5 controllers

 - i8042 now uses chassis info to skip selftest on Asus laptops as list
   of individual models became too unwieldy

 - miscellaneous fixes to other drivers

* Dialog DA9062/63 OnKey Module * Dialog DA9061/62/63 OnKey Module
This module is part of the DA9062/DA9063. For more details about entire This module is part of the DA9061/DA9062/DA9063. For more details about entire
chips see Documentation/devicetree/bindings/mfd/da9062.txt and DA9062 and DA9061 chips see Documentation/devicetree/bindings/mfd/da9062.txt
Documentation/devicetree/bindings/mfd/da9063.txt For DA9063 see Documentation/devicetree/bindings/mfd/da9063.txt
This module provides KEY_POWER, KEY_SLEEP and events. This module provides the KEY_POWER event.
Required properties: Required properties:
- compatible: should be one of: - compatible: should be one of the following valid compatible string lines:
dlg,da9062-onkey "dlg,da9061-onkey", "dlg,da9062-onkey"
dlg,da9063-onkey "dlg,da9062-onkey"
"dlg,da9063-onkey"
Optional properties: Optional properties:
- dlg,disable-key-power : Disable power-down using a long key-press. If this - dlg,disable-key-power : Disable power-down using a long key-press. If this
entry exists the OnKey driver will remove support for the KEY_POWER key entry exists the OnKey driver will remove support for the KEY_POWER key
press. If this entry does not exist then by default the key-press press when triggered using a long press of the OnKey.
triggered power down is enabled and the OnKey will support both KEY_POWER
and KEY_SLEEP.
Example: Example: DA9063
pmic0: da9062@58 {
pmic0: da9063@58 {
onkey { onkey {
compatible = "dlg,da9063-onkey"; compatible = "dlg,da9063-onkey";
dlg,disable-key-power; dlg,disable-key-power;
}; };
};
Example: DA9062
pmic0: da9062@58 {
onkey {
compatible = "dlg,da9062-onkey";
dlg,disable-key-power;
};
};
Example: DA9061 using a fall-back compatible for the DA9062 onkey driver
pmic0: da9061@58 {
onkey {
compatible = "dlg,da9061-onkey", "dlg,da9062-onkey";
