Add missing functions to query the single fixed frame size (960x540) and supported frame rates.

2015-05-30[media] reduce poll interval to allow full 60 FPS framerateFlorian Echtler1-1/+1
The SUR40 hardware can deliver images at up to 60 FPS; at full USB2 bandwidth, one raw frame will take about 11 ms to transmit. If the poll interval is above 5 ms, fully handling one frame will take longer than 16 ms and the overall frame rate will drop below 60 FPS. To get the full frame rate without blocking all the time and still allowing for a bit of timing jitter, we reduce the poll interval to 4 ms.

2015-05-22Input: smtpe-ts - wait 50mS until polling for pen-upMarek Vasut1-1/+1
Wait a little bit longer, 50mS instead of 20mS, until the driver starts polling for pen-up. The problematic behavior before this patch is applied is as follows. The behavior was observed on the STMPE610QTR controller. Upon a physical pen-down event, the touchscreen reports one set of x-y-p coordinates and a pen-down event. After that, the pen-up polling is triggered and since the controller is not ready yet, the polling mistakenly detects a pen-up event while the physical state is still such that the pen is down on the touch surface. The pen-up handling flushes the controller FIFO, so after that, all the samples in the controller are discarded. The controller becomes ready shortly after this bogus pen-up handling and does generate again a pen-down interrupt. This time, the controller contains x-y-p samples which all read as zero. Since pressure value is zero, this set of samples is effectively ignored by userland. In the end, the driver just bounces between pen-down and bogus pen-up handling, generating no useful results. Fix this by giving the controller a bit more time before polling it for pen-up.

2015-04-08[media] sur40: fix occasional hard freeze due to buffer queue underrunFlorian Echtler1-0/+5
This patch fixes a kernel panic which occurs when buf_list is empty. This can happen occasionally when user space is under heavy load (e.g. due to image processing on the CPU) and new buffers aren't re-queued fast enough. In that case, vb2_start_streaming_called can return true, but when the spinlock is taken and sur40_poll attempts to fetch the next buffer from buf_list, the list is in fact empty. This patch needs to be applied on top of the queued one adding V4L2 support to the sur40 driver.

Add support for the new T100 object which replaces the previous T9 multitouch touchscreen object in recent maXTouch devices. T100 provides improved reporting with selectable auxiliary information, and a type field for hover/stylus/glove reporting. The hovering finger support was based on Chung-Yih's work in the ChromiumOS downstream kernel: https://chromium-review.googlesource.com/#/c/219280/ Signed-off-by: Nick Dyer <nick.dyer@itdev.co.uk> Acked-by: Yufeng Shen <miletus@chromium.org> [javier: Factor out T9 and T100 init functions and rework hover support] Signed-off-by: Javier Martinez Canillas <javier.martinez@collabora.co.uk> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2015-04-03[media] add raw video stream support for Samsung SUR40Florian Echtler2-12/+419
This patch adds raw video support for the Samsung SUR40 using vbuf2-dma-sg. All tests from v4l2-compliance pass. Support for VB2_USERPTR is currently disabled due to unexpected interference with dma-sg buffer sizes.

input_register_device already sets the EV_SYN event since all devices can generate them. Remove the redundant affectation. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2015-03-24Input: edt-ft5x06 - allow to setting the maximum axes value through the DTMaxime Ripard1-0/+5
Currently the driver relies on some obscure and undocumented register to set the maximum axis value. The reported value is way too high to be meaningful, which confuses some userspace tools like QT's evdevtouch plugin which try to scale the reported events to the maximum values. Use the values from the DT to set meaningful values. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2015-03-24Input: of_touchscreen - register multitouch axesMaxime Ripard1-5/+17
So far, the DT parsing code was only setting up the regular input axes, completely ignoring their multitouch counter parts. Fill them with the same parameters than the regular axes.

2015-03-24Input: of_touchscreen - rework the DT parsing functionMaxime Ripard1-10/+40
The DT parsing function currently duplicates a lot of the code to parse the touchscreen DT properties. In order to ease further additions to this parsing routine, rework it slightly to create new helper functions.
