| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The touchscreen on the WinBook TW100 and TW700 don't match the default display, with 0,0 touches being reported when touching at the bottom right of the screen. 1280,800 0,800 +-------------+ | | | | | | +-------------+ 1280,0 0,0 It's unfortunately impossible to detect this problem with data from the DSDT, or other auxiliary metadata, so fallback to quirking this specific model of tablet instead.

| * Input: LEDs - skip unnamed LEDsDmitry Torokhov2015-07-241-2/+14
| | | | | | | | | | | | | | | | | | Devices may declare more LEDs than what is known to input-leds (HID does this for some devices). Instead of showing ugly warnings on connect and, even worse, oopsing on disconnect, let's simply ignore LEDs that are not known to us.

| * Input: usbtouchscreen - avoid unresponsive TSC-30 touch screenBernhard Bender2015-07-231-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a problem in the usbtouchscreen driver for DMC TSC-30 touch screen. Due to a missing delay between the RESET and SET_RATE commands, the touch screen may become unresponsive during system startup or driver loading. According to the DMC documentation, a delay is needed after the RESET command to allow the chip to complete its internal initialization. As this delay is not guaranteed, we had a system where the touch screen occasionally did not send any touch data. There was no other indication of the problem. The patch fixes the problem by adding a 150ms delay between the RESET and SET_RATE commands.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we are reporting the button state as inverted on all boards with an axp209 pmic, tested on a ba10-tvbox, bananapi, bananapro, cubietruck and utoo-p66 tablet. The axp209 datasheet clearly states that the power button must be connected between the PWRON key and ground. Which means that on a press we will get a falling edge (dbf) irq not a rising one, and likewise on release we will get a rising edge (dbr) irq, not a falling one. This commit swaps the check for the 2 irqs fixing the inverted reporting of the power button state.

Technically, the SUR40 supports any arbitrary frame rate up to 60 FPS, as it is polled and not interrupt-driven. For now, we just report 30 and 60 FPS, which is sufficient to make most V4L2 tools work.

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.

Simplify drivers accordingly. Note that in the case of the drv260x driver error checking is more strict now because -ENOSYS is reported to the caller now. But this should only be returned if GPIOLIB is disabled which shouldn't happen as the driver depends on GPIOLIB.

This allows to re-purpose and reassign LDEs on the keyboards to represent states other than the standard keyboard states (CapsLock, NumLock, etc). The old API of controlling input LEDs by writing into /dev/input/eventX devices is still present and will take precedence over accessing via LEDs subsystem (i.e. it may override state set by a trigger). If input device is "grabbed" then requests coming through LED subsystem will be ignored.
