2012-03-13Input: tegra-kbc - revise device tree supportOlof Johansson-5/+16
This is an incremental patch updating to the revised bindings for matrix keyboards. This includes an optional "linux,fn-keymap" binding that is not yet implemented, that will be used to specify the Fn-key modifier layout if needed.

2012-03-12Input: wacom - fix physical size calculation for 3rd-gen BambooJason Gerecke-2/+2
This calculation determines the physical dimensions of the tablet, used later on in calculate_touch_res to obtain the touch sensor resolution. Instead of dividing the logical size by the resolution, the current code performs a multiplication. This doesn't pose a problem for the 3rd-gen Bamboo since the resolution and scale factor happen to be identical, but will produce an incorrect result for other cases.

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.

2012-02-03Input: add infrastructure for selecting clockid for event time stampsJohn Stultz-4/+21
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.
