* Input: max8925_onkey - avoid accessing input device too earlyDmitry Torokhov2012-03-061-47/+44Star
| | | | | | | | | | | | | Input device must be allocated (but not necessarily registered) before requesting IRQs, otherwise there is a chance that IRQ handler fires and tries to reference not yet allocated input device. Also it makes sense to store relative IRQ numbers in max8925_onkey_info structure as they are needed in suspend/resume which we expect to be called more often than probe and remove.

These USB devices emulate an USB mouse by default, so one can also use the usbhid driver. However, in combination with special user space drivers this kernel driver allows one to customize the behaviour of the device.

* Input: add infrastructure for selecting clockid for event time stampsJohn Stultz2012-02-033-4/+25
| | | | | | | | | | | | | | | | | | | | | | As noted by Arve and others, since wall time can jump backwards, it is difficult to use for input because one cannot determine if one event occurred before another or for how long a key was pressed. However, the timestamp field is part of the kernel ABI, and cannot be changed without possibly breaking existing users. This patch adds a new IOCTL that allows a clockid to be set in the evdev_client struct that will specify which time base to use for event timestamps (ie: CLOCK_MONOTONIC instead of CLOCK_REALTIME). For now we only support CLOCK_MONOTONIC and CLOCK_REALTIME, but in the future we could support other clockids if appropriate. The default remains CLOCK_REALTIME, so we don't change the ABI.

| | | | | | | | | | | | | | | | | Cypress TrueTouch(tm) Standard Product controllers are found in a wide range of embedded devices. This driver add support for a variety of TTSP controllers. Since the hardware is capable of tracking identifiable contacts, multi-touch protocol type B (stateful) is used to report contact information. The driver is composed of a core driver that process the data sent by the contacts and a set of bus specific interface modules. This patch adds the base core TTSP driver.

| | | | | | | | | | | | | | | | | | | | | | | | | When runtime power management is enabled put the Samsung keypad driver into suspend mode with wakeups disabled whenever the device is open but a key is not actually been pressed. As well as saving a trivial amount of power this will support the use of SoC wide idle modes which put the entire device into a retention mode and use explicit wakeup sources to exit. Since not all of the interrupt controllers used with the driver support set_irq_wake() (though they all do the right thing) and there's a nasty WARN() when we disable wake after failing to enable it keep track of the current wake status from runtime PM and only disable wake if we managed to enable it; I'm not entirely sure why this doesn't affect the existing uses of the API in the driver. System suspend is unaffected as the driver core will runtime resume any suspended devices prior to system suspend.
