The irq_to_gpio() is old, most platforms use GENERIC_GPIO framework and don't support this API anymore. The i.MX6q sabrelite platform equips an egalax touchscreen controller, and this platform already transfered to GENERIC_GPIO framework, to support this driver, we use a more generic way to get gpio. Add a return value checking for waking up the controller in the probe function, this guarantee only a workable device can pass init.

Extend the amount of character devices, such as eventX, mouseX and jsX, from a hard limit of 32 per input handler to about 1024 shared across all handlers. To be compatible with legacy installations input handlers will start creating char devices with minors in their legacy range, however once legacy range is exhausted they will start allocating minors from the dynamic range 256-1024.

The Cintiq 24HD touch cannot use wacom_set_phy_from_res to determine the physical size of the touch sensor since the pen and touch are on separate USB devices. The physical size is, however, provided in the HID descriptor, just scaled to a unit we don't use. This patch introduces the function wacom_fix_phy_from_hid to let us make use of the unit and exponent data provided by HID to set the [xy]_phy variables to an appropriate value. This function relies on a trimmed-down version of hidinput_calc_abs_res from the hid-input.c. Signed-off-by:

The ability to set the proximity flag should apply to any device that has both pen and touch input. Rather than listing classes of devices known to meet this criteria, simply filter on the quirk defining all such devices. Signed-off-by:

This changes how the touch packets for Intuos5 and 3rd-gen Bamboo are interpreted, so that proper values for the MAJOR and MINOR axes are reported. Instead of using the amplitude field (data[6]), we use the size field (data[5]) and do some calculation to transform it from a scaled-down area into axis lengths. Note that even though we assume a circular contact, both MAJOR and MINOR are reported since the resolution of the X and Y axes differ. Signed-off-by:

If the ExpressKeys on the Intuos5 are touched, they currently result an out-of-prox packet being sent even if the pad is already out of prox. This can cause some confusion in the X driver. To restore the expected semantics, we make being touched a sufficient condition to signal proximity. https://bugs.freedesktop.org/show_bug.cgi?id=54250Reported-by:

Commit c039450 (Input: synaptics - handle out of bounds values from the hardware) caused any hardware reported values over 7167 to be treated as a wrapped-around negative value. It turns out that some firmware uses the value 8176 to indicate a finger near the edge of the touchpad whose actual position cannot be determined. This value now gets treated as negative, which can cause pointer jumps and broken edge scrolling on these machines. I only know of one touchpad which reports negative values, and this hardware never reports any value lower than -8 (i.e. 8184). Moving the threshold for treating a value as negative up to 8176 should work fine then for any hardware we currently know about, and since we're dealing with unspecified behavior it's probably the best we can do. The special 8176 value is also likely to result in sudden jumps in position, so let's also clamp this to the maximum specified value for the axis.

When lifing finger off the surface some versions of touchpad send movement packets with very low coordinates, which cause cursor to jump to the upper left corner of the screen. Let's ignore least significant bits of X and Y coordinates if higher bits are all zeroes and consider finger not touching the pad.

The logical scale is used to produce special finger width values to userspace, but has become an unnecessary restriction for everything else. Also, the bcm5974 trackpads are very accurate and work well without hysteresis. This patch simplifies the driver and device data by removing the logical scale, and by moving the special synaptics code out of the main path. Also add the orientation range, needed in a subsequent patch, to the device configuration. Tested-by:

Henrik Rydberg authored
The early generations with this trackpad used the separate mouse interface to produce button events. With the introduction of the button pads, this information was moved to the trackpad interface, leaving the mouse interface unused. The driver is still setting up both interfaces, which has not caused any problems - until now. It turns out that without the CONFIG_USB_EHCI_TT_NEWSCHED option, the driver may return an ENOSPC upon bt_urb submission, resulting in a failure to open the device. This happens everytime on the MacBookPro Retina (and likely on other mid-2012 models), but earlier MacBook models seem to work fine. This patch skips the bt_urb setup for TYPE2 devices, which arguably should have been done in the first place. Tested-by:

Most MT drivers perform the same actions on frame synchronization. Some actions, like dropping unseen contacts, are also unnecessarily complex. Collect common frame synchronization tasks in a new function, input_mt_sync_frame(). Depending on the flags set, it drops unseen contacts and performs pointer emulation. With init flags and frame synchronization in place, most MT drivers can be simplified. First out are the bcm5974 and hid-multitouch drivers, following this patch. Reviewed-and-tested-by:

By sending a full frame of events at the same time, the irqsoff latency at heavy load is brought down from 200 us to 100 us. Cc: Daniel Kurtz <djkurtz@chromium.org> Tested-by:

Henrik Rydberg authored
On heavy event loads, such as a multitouch driver, the irqsoff latency can be as high as 250 us. By accumulating a frame worth of data before passing it on, the latency can be dramatically reduced. As a side effect, the special EV_SYN handling can be removed, since the frame is now atomic. This patch adds the events() handler callback and uses it if it exists. The latency is improved by 50 us even without the callback. Cc: Daniel Kurtz <djkurtz@chromium.org> Tested-by:
