2012-01-23Input: samsung-keypad - don't synchronise with runtime PM putMark Brown1-3/+3
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.

2012-01-23Input: q40kbd - convert driver to the split modelDmitry Torokhov1-60/+79
Convert the driver to standard spilt model arch-specific code registers platform device to which driver code can bind later. Also request IRQ immediately upon binding to the device instead of doing this when serio port is being opened.

2012-01-23Input: nomadik-ske-keypad - do not assign driver's probe() methodDmitry Torokhov1-3/+2
Because we are using platform_device_probe() to register the driver we do not need to assign driver's probe method. We also can mark ske_keypad_probe(), together with ske_keypad_chip_init(), as __init instead of __devinit.

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.

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.

2011-12-31Input: evdev - only allow reading events if a full packet is presentDima Zavin1-1/+1
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: Dima Zavin <dima@android.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2011-12-30Input: samsung-keypad - implement runtime power management supportMark Brown1-7/+80
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.

2011-12-28Input: add driver for AUO In-Cell touchscreens using pixcir ICsHeiko Stübner3-0/+666
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.

There exist tilt switches that simply report their tilt-state via some gpios. The number and orientation of their axes can vary depending on the switch used and the build of the device. Also two or more one-axis switches could be combined to provide multi-dimensional orientation.

2011-11-24virtio-pci: make reset operation saferMichael S. Tsirkin1-0/+18
virtio pci device reset actually just does an I/O write, which in PCI is really posted, that is it can complete on CPU before the device has received it. Further, interrupts might have been pending on another CPU, so device callback might get invoked after reset. This conflicts with how drivers use reset, which is typically: reset unregister a callback running after reset completed can race with unregister, potentially leading to use after free bugs. Fix by flushing out the write, and flushing pending interrupts. This assumes that device is never reset from its vq/config callbacks, or in parallel with being added/removed, document this assumption. Signed-off-by: Michael S.
