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. Signed-off-by:

We don't actually care if the device has been runtime suspended immediately so we can just drop the reference without waiting for any state change to be implemented. This may allow us to avoid some suspend/resume cycles and is a bit more friendly to the rest of the system. Signed-off-by:

Several protocol initialization routines can fail after they set up psmouse methods, such as reconnect and disconnect. This may lead to these stale methods used with different protocol that they were intended to be used for and may cause unpredictavle behavior and/or crashes. Make sure we start with a clean slate before executing each and every protocol detection and/or initialization routine. Reported-by:

If there is a full packet in the buffer, and we overflow that buffer right after checking for that condition, it would have been possible for us to block indefinitely (rather, until the next full packet) even if the file was marked as O_NONBLOCK.

Without this, it was possible for the reader to get ahead of packet_head. If the input device generated a partial packet *right* after the reader got ahead, then we can get into a situation where the device is marked readable, but read always returns 0 until the next packet is finished (i.e a SYN is generated by the input driver). This situation can also happen if we overflow the buffer while a reader is trying to read an event out. Signed-off-by:

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. Signed-off-by:

Some displays from AUO have a so called in-cell touchscreen, meaning it is built directly into the display unit. Touchdata is gathered through PIXCIR Tango-ICs and processed in an Atmel ATmega168P with custom firmware. Communication between the host system and ATmega is done via I2C. Devices using this touch solution include the Dell Streak5 and the family of Qisda ebook readers. The driver reports single- and multi-touch events including touch area values. Signed-off-by:

Adds support for the Cintiq 24HD. There are two quirks about this model that haven't been seen in prior tablets. First, a second touch ring is present on this display; it is being exposed via the ABS_THROTTLE axis. Second, three capacitive buttons at the top of the unit are available; though physically a touch strip, we report the use of these buttons with generic KEY_ events. Signed-off-by:
